About DEMON SIEGE
What if raw 90s retro action, over-the-top horror, and endlessly stacking power-ups collided? Welcome to DEMON SIEGE. Forget balanced weapon tuning—in this aggressive arena wave shooter, you fight relentless hordes of demons in a race to break the game mechanics before they break you. Every upgrade you pick stacks infinitely, transforming you from a desperate survivor into an absolute god by the end of the run if your good enough.Speed-blitz the battlefield until the map becomes a gritty blur. Dump your points into jump height to escape danger entirely or rain down hell from above. Level up MULTI BULLET to force every gun in your arsenal to fire a ridiculous wall of lead doing insane damage, turning even your basic starter revolver into a devastating hand-cannon shotgun. The longer you survive, the more chaotic the build becomes.This pure arena wave shooter violence gets straight to the action with short, hyper-replayable survival sessions designed around total devastation. By combining the fast adrenaline of classic first-person shooters with the addictive, dopamine-heavy scaling of bullet heaven progression, there are no caps and no limits to the wildly overpowered character setups you can create. Discover ridiculous weapon and upgrade synergies that turn the screen into a chaotic mess of pixels and demon blood.Build a god. Break the siege.

Fun and very addictive little shooter, its an assault on the senses but it does all come together and work! Has a great levelling up system so your always getting more powerful in some way, voice lines made me laugh! Finished it in one sitting, but looking forward to trying out the endless mode.2 found this helpful
I had fun with it Simple retro shooter with simple mechanics. Its a low budget Doom copy as far as story and premise, but thats fine by me. Knife is probably the best weapon. I was streaming my live review and singing about stabbing demons. It was great. Worth it for a couple hours of fun I think2 found this helpful
