“COLLAPSE COMPANY” is a round-based horror roguelike action FPS for 1 to 4 players, in which a team explores procedurally-generated underground dungeons.
The primary objective of each mission is to activate the “Particle Acceleration Reactor” located at the deepest point of the dungeon.

In every round, players descend into a randomly generated dungeon, searching for scattered items and storing them in their inventory while advancing through the area.
The layout of corridors, room structures, item placement, and enemy positions change each round, requiring different routes and strategies every time.

The dungeon contains multiple enemy types with distinct behavioral patterns.
Some enemies close the distance when they are not being watched, some rush in quickly from walls or blind spots, and others hide and ambush the player depending on their position and movement.

Environmental elements such as darkness, narrow corridors, confined spaces, traps, and various mechanisms also act as hazards.
Resources and materials found during exploration can be carried back to the base, sold for credits, and used to restock supplies or prepare equipment for the next run.

The game has no definitive final stage or ending and progresses in a round-based structure.
After activating the “Particle Acceleration Reactor,” the team must escape the dungeon within a time limit.
Rounds continue until the team fails to evacuate in time or is completely wiped out.
Venturing into higher-risk areas increases both the danger and the potential rewards.
