Infested

Infested is a seven-level (plus intermissions) PK3 for Doom II, created by ginc. Built for GZDoom, Infested includes custom monsters, weapons and textures. The gameplay also features scripted arena-like encounters where the player must deal with Gore Nests that summon waves of monsters.

Episode 1 was released in November 2021, and Episode 2 was released in October 2022.

Infested was one of the recipients of the 2021 Cacowards.

Plot
Two years after Hell on Earth and the fall of the Icon of Sin, the player is an independent contractor for Demon-B-Gone, a demon extermination company. Sent to deal with an infestation of demons at an art gallery in a small town, they soon find that this is not a routine clean-up job...

Custom monsters
The nests must be destroyed to progress through the maps.
 * Gore nests are stationary growths that will trap you in their territory when revealed. When damaged enough, they will shield themselves and summon reinforcements. Clear out enough demons and they will lower their guard to launch salvos of fireballs at you.


 * Blood demons (and blood spectres) can move and bite faster.
 * Shadow imps can toss double fireballs that travel twice as fast.
 * Plasma zombies can move faster and shoot 2-round bursts of plasma.
 * Baby cacodemons can fly faster and are dangerous in swarms.
 * Mama cacodemons are beefier, shoot volleys of lightning balls, and spawn babies when killed.
 * Lesser cyberdemons have less health but can fit into smaller spaces.
 * The Annihilator is a beefier cyberdemon armed with dual rocket launchers and acts as the boss of Episode 1. It can deliver salvos of rockets from the ground and the air.
 * Raging spirits are super-aggressive lost soul variants.
 * Rage elementals are pain elemental variants that spew raging spirits instead of lost souls.
 * Hell shamans are Hell noble variants that can deploy totems that launch baron projectiles.
 * The Demolisher is a beefier spider mastermind and acts as the boss of Episode 2. It can launch homing firebombs and use a mega-chaingun.

Custom weapons

 * The pistol fires more quickly and accurately.
 * The plasma pistol (Episode 2 starting weapon) fires plasma balls.
 * The shotgun fires 9 pellets (increased from 7), but has more spread.
 * The machinegun is similar to Doom II's chaingun.
 * The dual-mode shotgun has two fire modes: primary fire is identical to Doom II's super shotgun, while alt-fire uses a single shell.
 * The heavy chaingun has two fire modes: primary fire is twice as fast as the machinegun, while alt-fire is slower but more accurate.
 * The armor-piercing rocket launcher has two fire modes: primary fire launches AP rockets, while alt-fire launches standard explosive rockets. On detonation, AP rockets launch a penetrating charge that passes through monsters and bounces off walls, floors and ceilings for a short distance.
 * The spread gun has two fire modes: primary fire launches plasma balls in a spread pattern (50% faster than Doom II's plasmagun), while alt-fire produces a standard plasma stream like the original plasmagun.
 * The BFG9000 behaves just like it does in Doom II, but uses its own ammo type instead of cells.
