DUKE PLUS

A GAME ENHANCER AND CUSTOMIZER FOR THE EDUKE32 PORT OF DUKE NUKEM 3D

by Dan Gaskill (a.k.a. “DeeperThought”)

TO INSTALL AND PLAY:

1. Extract the contents of DUKEPLUS.RAR into a folder that contains the file “DUKE3D.GRP”
2. Double-click on the included dukeplus.bat
3. OR, if you don't use the .bat: Launch the included EDuke32.exe. DO NOT click the Start button yet. Select the Game tab and then select DukePlus from the gamedir menu. Now click Start. The next time you launch EDuke32, Duke Plus will already be selected.
4. To use the HRP with Duke Plus: Place “duke3d_hrp.zip” into a folder named “autoload” in your Eduke32 folder.
5. In the EDuke32 main menu, select OPTIONS->KEYBOARD SETUP and assign keys for "RELOAD ALTFIRE" and "DUKEPLUS MENU".

TO CUSTOMIZE DUKE PLUS: There is an in-game menu accessed by the DUKEPLUS MENU key. Options set in the menu will remain set the next time you start a game (they are saved in duke3d.cfg). There are some some additional options that can only be accessed in the file “USERPLUS.CON” inside the DukePlus folder.

TO AVOID PROBLEMS: If you have an autoload folder, make sure that it only contains the HRP files (duke3d_hrp.zip and hrp_update.zip). Any other files in autoload will likely cause problems. Also, none of the files for Duke Plus (except for dukeplus.bat) should be located outside of the DukePlus folder. This includes USERPLUS.CON, DUKEPLUS.CON, LIGHTS.CON, dukeplus.def, and the DUKEPLUS_RESOURCES folder.

Weapon Options*

WEAPON | DUKE PLUS OPTIONS*

MIGHTY BOOT

KARATE KICKS
Move forward while pressing QUICK KICK and Duke will perform a stepping side-kick. Press backward and QUICK KICK and Duke will perform a spinning hook kick (more damaging than the side-kick, but leaves the player more vulnerable). You have a finite amount of kick energy that will replenish over time.
LASER PISTOL
Laser pistols have a limited battery which can be replenished only by picking up more laser pistols. Hold down alt-fire to charge the pistol for a more powerful shot. When holding a laser pistol, it will replace the mighty boot weapon. However, you can still kick using the QUICK KICK key.

PISTOL | RELOADING The HUD shows how many bullets remain in your pistol clip(s). You can reload at any time by pressing the RELOAD/ALT-FIRE key (replaces CENTER VIEW). AKIMBO PISTOLS When this feature is on, Duke will wield two pistols at once after picking up a second pistol. Once you have a second pistol, you can toggle between using one or two by pressing the WEAPON 2 (pistol) key. Akimbo pistols are less accurate than a single pistol, but the firing rate is doubled.

SHOTGUN

CRUIZER SHOTGUN
Replaces Duke’s standard shotgun with the Duke Nukem Mossberg Cruizer, which uses a new model and sounds (see credits below). It has a clip that holds eight shells, which can be reloaded at any time using the reload key, or reloads automatically when the clip is depleted. Press fire during the reloading sequence to cancel and start shooting.
DOUBLE-BARRELED SHOTGUN
A sub-weapon of the shotgun (press 3 to switch to it from the regular shotgun, if you have picked it up). It will not normally appear in the game (it is tile 6324 and can be placed in maps manually) but there is an option in the monster sub-menu to make some pigcops use it (and drop it when they die).

CHAINGUN

MP5 SMG
Replaces Duke’s standard chaingun with an MP5 that has a 30 round clip. It is powerful than the chaingun, but this is balanced by there being less available ammo and the need to reload. Like the Cruizer shotgun, it can be reloaded using the reload key if you don’t want to wait until the clip is empty.
OVERHEAT (for standard chaingun only)
When this feature is on, the chaingun has double its maximum ammo capacity, does slightly more damage than normal, and can overheat. When you fire the chaingun, an overheat bar will appear in the HUD and begin to fill. As the chaingun gets hotter, the word “OVERHEAT” will be displayed – when the word starts flashing, the gun is near overheating. If it overheats, you cannot fire again until it cools down.

ROCKET LAUNCHER | HEAVY ROCKET LAUNCHER Does more damage, with a larger blast radius and faster rockets. This is balanced by the need to reload it (two rockets per clip), and the fact that rocket packs contain fewer rockets if the big rocket launcher is used. The alt-fire on the heavy rocket launcher fires a volley of cluster rockets.
PIPEBOMBS | Press the reload/alt-fire key to switch between trigger mode (the standard mode in which pipebombs are detonated by a trigger) and timer mode (in which pipebombs detonate after about 2 seconds). If “BETTER PIPEBOMB THROWS” is enabled, holding down fire will show the pipebomb’s trajectory and maximum throwing distance is increased.
SHRINKER | Press the reload/alt-fire key to switch between shrinker mode and mind blast mode. In mind blast mode, the weapon will cause enemies fight on your side for a period of time (stronger enemies are affected for a shorter durtation).
DEVASTATOR | Press the reload/alt-fire key to switch between rocket mode and shotgun mode. Shotgun blasts coming from the Devestator are less accurate and less damaging than the regular shotgun. However, the increased rate of fire more than makes up for this. A useful mode for close quarters (to avoid suicide) or cause instant damage at long range (great for multiplayer).
LASER TRIPBOMBS | MONSTER CAPSULES (a.k.a. Dukemon) The player starts with three capsules, which take the place of the tripbombs and look like pipebombs (but are larger and colored when thrown). An empty capsule will attempt to capture any nearby monster once it is deployed. The power of the capsules increases as you capture monsters, allowing you to capture stronger monsters. After a capture, retrieve the capsule. If you throw that capsule again, the monster will be released and will fight on your side. You can re-capture the monster to store it for future use and restore its health, but capturing monsters that are already allies does not increase your capsule power To switch between the different capsules you are holding, press the RELOAD/ALT-FIRE key. The contents of the currently selected capsule are displayed in the HUD.
FREEZER | Select Freezer Plus in the DP menu for the enhanced Freezer. FREEZE BEAM The primary fire is a beam that freezes enemies. Hits instantly with perfect accuracy. ICE COMETS The Alt-Fire key shoots three little ice comets which move very fast. They can bounce once. Good for finishing off frozen enemies, or just killing them outright.
EXPANDER | GRAVITY GUN Use the Alt-Fire key (same key as reload) to pull distant objects toward the player and hold them. Once an object is held, press fire to shoot it at high velocity. Firing when an object is not held will shoot a beam that pushes objects away.
KNOCKBACK | The shotgun and other high damage weapons have the ability to knock monsters backwards. The amount of knockback is adjustable.

*Optional features can be toggled on or off using the in-game menu

Player Abilities

MANTLING ABILITY WITH LOWERED JUMP HEIGHT* | When this feature is on, Duke will automatically grab onto ledges. He can hang, there, move sideways (if the ledge allows), or press JUMP to climb up. Press TURN AROUND to glance behind you while mantling.
DODGE MOVES* | Double tap on a direction key to quickly dodge in that direction. Jump while in mid-dodge to perform a long jump. While touching a wall, jump up and dodge away from it (i.e. if the wall is directly behind you, double-tap forward) to perform a wall jump.
RUNNING* | More realistic acceleration.
FOOTSTEPS | Sounds depend on the surface being stepped on.
GRABBING/THROWING* | If this ability is turned on, press OPEN on an object to pick it up. Press FIRE to throw a held object or OPEN again to drop it. You can also use quick kick on a held object and it will fly away (or be destroyed).
WORKING COLA MACHINES | Press the open key while facing a cola machine to insert coins. On the third coin, it dispenses a can, which will roll across the floor if unobstructed. You can pick up the can by pressing the OPEN key on it. Pressing FIRE will drop the can, while pressing OPEN again will make Duke open the can and drink the cola (5 health). After drinking the cola, Duke will drop it and stomp on the can if close. You cannot drink from a can that has been damaged or has already been opened. Breaking the cola machine will cause it to dispense a random number of cans.
FLARES* | When USE_FLARES is set to ON, Duke can take out a flare with the USE FLARE key (replaces the AIM DOWN key). The flare will light up nearby areas, making it easier to see. Place the flare by pressing the USE FLARE key again, or throw it by pressing FIRE. By default, you can have up to three flares spawned at one time (this number can be changed). If you want so spawn a new flare but have reached the maximum number, you must either destroy one of the existing flares or wait for it to expire. If the USE_FLARES feature is on, the Duke Plus dynamic lighting system is loaded up when the game starts. Depending on your computer and on how many flares or other dynamic lights have been spawned, you may experience low frame rate. There are various options in USERPLUS.CON for tweaking the settings of the lighting system which can effect performance and quality.

ENHANCED INVENTORY ITEMS*

If STOREHEALTH is set to YES, unused health items are stored in the first aid kit.

If STEROID EFFECTS is set to YES, kicks do 4X damage when the player is using steroids, and everything in the game world will seem to slow down, except for the player's movement.

If HOLODUKELIGHTNING is set to YES, the HoloDuke hologram will electrocute monsters who wander close to it.

IF GOGGLESWITCHES is set to YES, the nightvision goggles will reveal which dip switches need to be set.

BULLET SPREAD* | Change the degree to the player's bullets spread (pistol, shotgun and chaingun may be set separately)

* Ability is optional. Most optional abilities can be toggled using the in-game menu, and some can be turned on by editing USERPLUS.CON

Duke Plus Map Effects

In Duke Plus, it is possible to make working ladders, tranparent water, multistop elevators, and many other new map effects. See the guide for complete descriptions of the effects and how to include them in your map:

DUKE PLUS MAP EFFECTS GUIDE

Miscellaneous Features

The Duke Plus In-Game Menu

When you start a game using Duke Plus for the first time, you will see a message at the top of the screen telling you to bring up the menu, using the menu key (which you may assign in the Eduke32 main menu under OPTIONS -> KEYBOARD SETUP). The menu is divided into five sub-menus: WEAPONS, ABILITIES, MONSTERS, and EFFECTS, WEATHER, and DUKEBOTS. The weapons and abilities options have already been described above in the WEAPON OPTIONS and PLAYER ABILITIES sections. The monster options are as follows:

SHOW MONSTER LIFE BARS -- The length of a bar over a monster's head indicates the amount of remaining life it has left. Damaging a monster causes the bar to flash. Note that this feature applies to Duke bots as well.

RANDOM ATTRIBUTES -- Randomized monsters can spawn with various attributes that normal monsters don't have. They may have more health, use different attacks, drop different items, teleport, use different tactics, or be immune to certain weapons. The number you set here is the probability that the monster will have each of the possible random traits. Generally speaking, the higher the number, the more challenging the game will be. See the MONSTER FLAGS table below for a list of the different attributes.

DAMAGE INFLICTED -- This is the percent of normal damage that the monsters inflict on enemies. 100 by default.

DAMAGE RECEIVED -- This is the percent of normal damage that the monsters receive from the player. 100 by default.

MONSTER IN-FIGHTING -- Set to YES if you want monsters to fight each other after friendly fire incidents (like in Doom).

TROOP CAPTAINS DROP LASERGUN -- Lizard troopers with red backpacks (pal 21 LIZTROOPS) will drop laser pistols when they die, which the player can use..

DOUBLE MONSTERS & EXTRA AMMO -- Does what it says.

ENHANCED AI -- Set to YES to change the enemy behavior for greater challenge. Changes include:

- Enemies have greater ability to follow the player
- Enemies will try to avoid the player lying in wait for them, depending on conditions
- Most enemies can strafe
- Enemies attempt to avoid pipebombs
- Enemies may come to investigate if they hear a nearby bullet impact or explosion
- Most enemies will tred water instead of falling into underwater areas
- Pigcops have the ability to fire tear gas grenades
- Lizard troopers have increased firing rate
- Some lizard troopers are medics with blue backpacks and will heal their allies
- Enforcers have a new spit attack which releases poison gas
- Octabrains have a telekinetic pull attack
- Commanders can dodge missiles, then use a "frisbee" attack

The effects menu options are as follows:

DAMAGE EFFECTS -- Set to YES for special decals and other effects caused by weapons

MIRRORED MAPS -- Causes all levels to become flipped on the X plane. Good for adding replay value to familiar maps. Known bug: some swing doors will open in the wrong direction.

DOUBLE-SIZED MAPS -- Maps are scaled up 2X. The player is given extra jumping height (hold down the jump key for extra height) so that the larger maps are still passable. Use in conjunction with the double monsters option (in the monsters menu) for added challenge. Known bugs: Some sprites are already so large that they cannot be doubled in size; this could make some maps impossible (e.g. if the affected sprites were part of a sprite bridge). Some map effects which depend on timing and distances may be spoiled.

ITEM QUOTE STYLE -- Choose from 3 styles for item pick up messages. In addition to the classic style (large messages across the top), you can choose Duke Plus style (quotes flash, and item quotes can be displayed in combination with another quote, such as a secret area message), or Dukematch style (small messages on the side of the screen)

NEW SOUNDS -- Replaces some sounds from the original game with new ones.

HI RES BLOOD -- Replaces the 8-bit blood pools with hi-res 32-bit color ones

WATER SPLASHES -- Adds new water splashing effects

PIGCOP JIBS -- Adds modelled jibs for pigcop body parts.

SMOKE AND TRANSTAR -- Replaces smoke puffs and transporterstar effects with higher quality versions

F7 VIEW MODE – Toggle between the classic over-shoulder view, and the new dynamic view. In dynamic view, the player is followed by a camera which attempts to get the best view of the action. A line of sprites from the player shows where Duke is looking/aiming. If you crouch while facing an enemy, the line will turn read, indicating a target lock. Once locked, you can uncrouch and you will continue to aim at the enemy until it dies or you press the use key to unlock.

The weather menu options are as follows:

WEATHER TYPE -- Can be set to rain or snow.

WEATHER COLOR -- 0 = standard, 1 = blue, 2 = red, 4 = black, 6 = green with inverted brightness, 7 = yellow, 8 = green, 13 = gray. Most of the other colors do nothing, but feel free to experiment...

WEATHER TRANSPARENCY -- 0%, 33%, or 66%

WEATHER SEVERITY -- The number of weather sprites that are spawned every tic.

RADIUS -- The maximum distance from the player that weather sprites will spawn.

HUD Display

- When Duke is holding his breath underwater, a bar appears near the top of the screen showing how much oxygen he has left.
- The number of rounds left in the clip of your current weapon is displayed in the lower left corner. This includes the pistol and the optional replacements for the shotgun and chaingun.
- If you are using a trooper laser gun, the energy remaining will display as a bar. If you charge a shot using alt-fire, another bar appears indicating whether the charged shot is ready.
- If you use a special kick, your remaining kick energy will display as a bar (it regenerates).
- If any Dukebot allies are active, the number remaining is displayed in the upper right corner.
- If you are using the monster capsules optional replacement for trip bombs, the HUD shows your capsule strength and the monster (if any) held in your currently selected capsule.

Map Display

- Access card readers you have visited are displayed in the map view (but only in the detailed map view that shows textures)

Duke Bots

- If BOT ASSISTANCE is set to YES in the monsters sub-menu, then when you start a single player game, a group of friendly Duke bots will fight alongside you. These Duke bots take the place of the player sprites with a lotag of 1, ( the multiplayer starting positions). Therefore, this option only works on maps that have multiplayer starting positions.
- All Duke bots start with pistols, and can have additional weapons. Some are medics (green pants) who can heal themselves, the player, and other bots on contact. Bots do not pick up items. They do have a limited supply of ammo, but it replenishes over time. Medics use up ammo when healing.
- You can order a Duke bot to patrol a certain area. Aim at the Duke bot and press the open key (spacebar by default) to select it. Then point to where you want it to patrol and press the open key again to set a patrol point. To cancel a patrol, press the left and right strafe keys simultaneously while the Duke bot is selected. This option has been disabled as of DP 1.8, though it is still possible to make a bot patrol using mapster.
- For information on how to use bots in your own maps, see the Duke Plus Map Effects Guide.

Changelog

1.99 2-08-09

-New optional Freezer Plus (activate in the weapons menu). Primary fire is a freeze beam, secondary fire shoots little ice comets. The freeze beam is much more useful than those stupid bouncy crystals ever were (especially with autoaim on)
-New version of Spiker's Project Zero level (see the movies page at the DP web site for a complete and EPIC playthrough)
-Fixed a recently introduced bug which had prevented rain or snow from starting in levels where it had been added (for example, WCTime and the intro hub level)
-Small improvements to the dynamic F7 mode (if you didn't like it before, you still won't like it)
-Fixed a bug which allowed sharks to come out of transparent water (they might still do it, but not because of THAT bug at least)
-Two things I forgot to mention in the last update: The player's footstep sounds work consistently now, and the timer mode of the pipebombs is actually useful now because I shortened the fuse

1.98 2-01-09

-New Dynamic F7 view mode option in the Effects menu:
Toggle between the classic over-shoulder view, and the new dynamic view. In dynamic view, the player is followed by a camera which attempts to get the best view of the action. A line of sprites from the player shows where Duke is looking/aiming. If you crouch while facing an enemy, the line will turn read, indicating a target lock. Once locked, you can uncrouch and you will continue to aim at the enemy until it dies or you press the use key to unlock.
-New Better pipebomb throws option in the Weapons menu (hold fire for longer range, shows trajectory)
-Additions to Enhanced monster AI option: Some lizard troopers are medics (they wear blue and heal their allies), and pigcops will sometimes use teargas grenades when they don't have a clear shot with their gun
-Shrunken monsters can be squished by any of their enemies, not just the player (especially useful if you have a captured newbeast fighting on your side)
-Eggs captured by a moncapsule will spawn a small (allied) newbeast instead of a slimer. Recapsule the newbeast and it becomes a full grown newbeast when released again.
-many small bug fixes and changes

1.97 1-06-09

-Dukebots now respawn after an interval, instead of instantly
-The Skycar is now more pilot friendly. When you get in, it does not move until you press the accelerator key. When landing (that is, if you are near the ground) you can bring it to a complete stop before getting out. You can still steer the Skycar when it is stopped. These improvements will come in handy for an upcoming map that will be released with DP version 2.0.
-Made some optimizations which may improve performance in some situations.
-Changed "tiles024.art" to lowercase for linux users who were plagued by an errant uppercase letter.
-Added a few more tiles to NAMES.H (so that names show up in Mapster)
-Added the -forcegl command line to the launcher, because I would rather have Intel gpu users complain to me about a black screen then have them tell me that they can't see my weapons since they are stuck in the software renderer.
Fixed the following from the original game (thanks to Hendricks266 for bringing these to my attention):

- Protector Drones resize on map load (like the other enemies)
- All monsters deduct one from the player's kill count when they respawn (before only Octabrain did that)
- Hydroplant (tile #969) no longer glitches when broken

1.96 12-23-08

-Dukebots have their own submenu now. They can be made to respawn, you can choose how many bots you want, and they will spawn in any map
-Added laser pistol option to monster menu. When on, pal 21 liztroops will drop them
-Improvements to laser pistol
-Improved monster pathfinding code for advanced AI
-Added some new sounds
-Removed game speed option (temporary)

1.95 12-21-08

When the enhanced AI option is on, lizard troopers will drop laser pistols (the weapons they actually use!) instead of pistol ammo. To use the laser gun, switch to mighty boot (weapon 1). Hold alt-fire to charge it for a more powerful shot.

1.94 12-15-08

All of the DP tiles that were in tiles013.art have been moved to tiles024.art. The main advantage of this is that Duke Nukem maps that use tiles013.art for custom art are now compatible with DP. Unfortunately, it means that any DP maps that contain DP sprites with the old tile numbers will need to be updated. I have already updated the maps that come with DP. The following tile numbers have changed:

CRATE1 6314 (was tile 3498)
CRATE2 6316 (was tile 3500)
FUSE 6319 (was tile 3503)
DBSPRITE 6324 (was tile 3508 ) -- this is the double-barreled shotgun pickup

-tweaked HUD defs so that the DP weapons don't glitch with animation smoothing
-adds a melee attack to the double-barrel shotgun (use alt-fire button)

-karate kicks can be turned on/off in menu
-karate kicks kill attached slimers
-laser sparks are turned on/off with damage effects menu option
-new transition effect which works like sleeper SE but can be used multiple times

1.91 11-1-08

-Game speed can now be controlled in the main DP menu
-Fixed a crash bug
-Moncapsules are easier to use (they break open on impact)
-Added option for enhanced AI in the monster sub-menu
-Added support for the Skycar vehicle (but maps for it will not be included until later)
-Improved muzzleflash for Mp5 (thanks to Gambini)

-Fixed a bad sizeat command

1.85 9-26-08

-Includes an overhauled version of Mia Max's Desert Base level

The new kicks are still experimental, and are not mentioned in the menus or documentation.
-Trooper lasers now have an impact effect and sounds
-Added cluster rockets as the alt-fire mode for the heavy rocket launcher
-Monster in-fighting is now on a percentage system instead of either ON/OFF. The higher the %, the more likely a monster is to retaliate if hit by friendly fire. The default is 40%, but you may need to adjust it if you are using the cfg from a previous version.
-New sound variations for explosions
-Fixed a bug which caused pal 1 monsters to have 1 strength.
-Fixed a bug which prevented the player from throwing an object with his hands while holding the gravity gun.
-If the cruizer shotgun is disabled in the menu, then the player will not acquire the cruizer shotgun when picking up a double-barreled shotgun (so you can now switch between the original shotgun and the db shotgun, if desired)

1.83 9-01-08

-Includes the latest build of EDuke32 (as always)

1.81 8-25-08

-Reverted to the old method of having DP load the player's normal DEFS.CON and USER.CON, rather then DP's own versions of these. I realized that loading special DP copies of these was preventing people from using the HRP music and other custom content specified in their CONs. The downside to this is it means I will get false bug reports again from people trying to use non-Atomic CONs with Duke Plus.
-Added the nocompress parameter to the texture defs AGAIN, this time in the correct place
-Fixed some bugs with the turrets that are attached to Sentry Drones (like the ones in Project Zero)

-Reduced the max speed at which a monster can be knocked back, in an attempt to prevent glitches
-Fixed a bug which caused the MP5 to show the reloading animation when it ran out of bullets
-Made some tweaks to the monster doubling and randomized monster features in an attempt to fix bugs (not sure if they are fixed)
-Fixed a bug where after picking up the double barreled shotgun it could become impossible to switch to the other shotgun
-Includes the latest EDuke32 which compiles the CONs much faster, resulting in a shorter startup time

1.80b 8-22-08

-Fixed a bug which caused FIRELASER to display as a black box when software rendering was used
-Eliminated some annoying log errors
-Turning off damage effects will now prevent extra debris from spawning from pipebomb explosions.
-Fixed an error in this manual (wrong tile number for double barreled shotgun)
-Added the nocompress parameter to the texture defs, to prevent possible problems caused by reduced texture quality settings
-Now using the scriptsize command to prevent potential problems caused by auto-increasing the script buffer size
