About This Game

What if classic boomer shooters, over-the-top horror, and endlessly stacking powerups collided?

Welcome to DEMON SIEGE.

Fight through relentless waves of demons in a fast-paced retro-inspired FPS where YOU become the final boss by the end of a run. Every powerup stacks infinitely, letting you create absurdly powerful builds and completely change how you play.

Stack movement speed until you become a blur across the battlefield.

Dump everything into jump height and launch yourself into the sky.

Level up MULTI BULLET and transform every weapon in your arsenal into a devastating shotgun — even your revolver.

The longer you survive, the more insane your character becomes.

DEMON SIEGE combines the aggressive action of classic boomer shooters with addictive progression systems inspired by survival horde games. Every level-up matters, and every run lets you experiment with new overpowered combinations.
