Keep Calm and Kill Demons

Wave-Based FPS With Procedural Levels

You're trapped in a demon-infested town with only a revolver, an AK-47, and a strong desire to not die horribly.

There is no way out, and the demons keep pouring in through portals. All you can do is take a deep breath, crank up some punk tunes, and fight them off while delaying the inevitable.

How long can you keep it up?

Features

• Fast-Paced Combat: Simple but satisfying shooting mechanics – move, aim, fire, reload, repeat.
• Wave-Based Survival: The next wave won’t spawn until you’ve cleared the current one – take your time, but don’t get too comfortable.
• Procedural Levels: Enter a seed to generate a unique map layout for each session.
• Save & Resume: Pause anytime and continue where you left off.
• Performance Tracking: Keep tabs on kills, accuracy, survival time, and more.
• Mini-Map: See enemy positions and useful items at a glance.
• In-Game Radio: A punk rock soundtrack blasts from a carryable radio – take it with you or leave it behind. Not feeling the current track? Just shoot it to skip to the next one.
• Atmospheric Audio: Gunfire, enemy growls, surface-based bullet impacts, and more.
• A Fun Detail: Shooting demons mid-spawn knocks them back into the portal instead of landing.
