Description: A set of 12 UDMF single player levels. They start off relatively simple and straightforward but become progressively more complex and ambitious. Requires GZDoom. Pistol start is enforced for every level, and jumping/crouching is disabled. Freelook is strongly recommended. Mostly vanilla-style gameplay although utilises certain modern features such as 3d floors, slopes, wormhole portals, and custom monsters. Levels take place in a variety of settings, alternating between Earth/techbase and Hell. Map design is mostly non-linear, with different paths that can be tackled in any order, although this varies by level. The WAD as a whole is probably slightly on the easier side, however, there are two special extra difficulty levels (Insane and Hellish) for those seeking a greater challenge.

Story: Following disturbing reports claiming that the inhabitants of a nearby UAC military complex and research facility have lost their minds, and apparent sightings of 'monsters', you have been sent to investigate. Lethal force is authorised if necessary.

Requirements: Doom 2 IWAD and GZDoom (this has only/mostly been tested with GZDoom, it likely will not work properly with other source ports). Hardware rendering is recommended.

- Pistol damage increased by 40%, and fire rate increased by 15%
- Default max ammo amounts increased
- Starting ammo increased by 100%
- Lost Soul health reduced by 30%
- Health and armour bonus effects increased by 100%
- Plasma Rifle projectile speed increased by 20%
- Revenant missiles have a 100% chance to be homing, but the homing strength is significantly reduced
- Revenants drop a single rocket upon death
- Chaingunner damage is slightly less variable and slightly lower on average
- Barons of Hell are slightly bigger and move faster
- Radiation Suits respawn
- Chainsaw and BFG replaced with new, modified custom weapons

Difficulty settings (all implemented):
- 'Beginner' - same as 'I'm too young to die'
- 'Easy' - same as 'Hey not too rough'
- 'Medium' - same as 'Hurt me plenty'
- 'Hard' - same as 'Ultra-Violence' except melee demons and monster projectiles move slightly faster
