Killroom Protocol

Controls:

• WASD — Move
• Mouse — Look around
• Left Click — Shoot
• Right Click — ADS

How to play:

Trial Mode is the main roguelite mode. You start in a slower survival horror phase where you explore, gather Credits, buy weapons and ammo, upgrade your chances, and prepare before corrupting the system. Once the system is corrupted, the run shifts into Kill Them All: a faster combat phase with objectives, enemies, rewards and escape pressure.

If you want immediate action, start with Challenges or Infinite Arena instead. These modes skip most of the slower preparation and throw you directly into combat.

Killroom Protocol is a fast-paced, low-poly arena FPS set inside a deadly alien hunting simulation.

Every run is different. Fight hostile Hunters, survive deadly events, buy weapons and ammo, upgrade your body, and escape before the simulation consumes you.

This is v0.3, the first public release. The game is fully playable but still in active development. More stages, enemies, weapons, events, balance improvements, and performance optimizations are planned. Feedback is greatly appreciated.

Play directly in your browser for free. Optional donations help support development.

Basic tips:

- Use terminals to buy weapons, ammo and supplies.

- Ammo is limited. Pick up ammo drops from the ground.

- Watch the Abduction bar. If it reaches the limit, you are captured.

- Optional events are dangerous, but give better rewards.

- Unlock skins and upgrades between runs.
