About this game
“COLLAPSE COMPANY” is a co-op horror roguelite action FPS for 1–4 players, centered around repeated expeditions into underground dungeons.
Your primary objective is to activate the Particle Accelerator Reactor located at the deepest level of the dungeon and escape alive.
Each round sends players into a procedurally generated dungeon, where they must explore, search for scattered items, collect resources, and manage their inventory while progressing deeper underground.
Corridor layouts, room placements, item locations, and enemy spawns change every round, requiring players to adapt to new routes and unpredictable situations each time.
The dungeon is populated by multiple enemy types with distinct behaviors: some close in while out of sight, others ambush from walls or blind spots, and some remain hidden, waiting patiently for the right moment to strike. Enemy behavior dynamically reacts to player movement and positioning.
The environment itself is also a constant threat. Darkness, narrow corridors, confined spaces, environmental hazards, traps, and various gimmicks all add to the risk.
Resources and materials discovered during exploration can be brought back to the base, sold for currency, and used to prepare supplies or purchase equipment for future runs.
The game does not feature a fixed final stage or ending. Instead, it progresses in rounds.
After activating the Particle Accelerator Reactor, players must evacuate the dungeon under a strict time limit. The game continues until the team fails to escape or is completely wiped out. By challenging increasingly dangerous areas, players can earn greater rewards at higher risk.
A save system is implemented, allowing players to carry over their money and owned weapons into subsequent expeditions.
