About
DEMON SIEGE is a compact, retro-inspired Micro-FPS Bullet Heaven built by a solo developer using the limited but intentionally old-school EasyFPSeditor engine.
This isn't a massive 4-hour campaign. Instead, it's a fast experience inspired by classic boomer shooters, arcade score chasing, and modern bullet heaven games.
Fight through demonic hordes, earn gold, buy upgrades from vending machines, and create absurd builds where every upgrade stacks infinitely. Become impossibly fast until your boots catch the terrain on fire, leap across the map, fire walls of bullets, and see just how far you can push the game's systems.
The engine was originally designed for much simpler Wolfenstein 3D-style games, so DEMON SIEGE embraces that retro DNA while stretching the technology far beyond its intended limits. Rather than chase modern graphics, the focus has always been on satisfying combat, addictive progression, and overpowered builds in a retro engine.
Fast-paced retro FPS combat
Infinite stacking upgrades that create wildly different builds
Killstreak announcer with bonus gold rewards
Vending machine progression during each run
Free post-launch content updates planned
If you're looking for a polished AAA shooter with huge levels and cinematic storytelling, this isn't that game.
If you love old-school FPS games, indie experimentation, and watching your character become a ridiculously overpowered GOD in under an hour, DEMON SIEGE was made for you.

Great fun game, can be played in an hour. worth the time if you want something different. was not expecting this from basically the old Wolfenstien engine
game is fun
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.
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 think
This was good. Very short, but I enjoyed it.
Wow! Many demons. Such hot. Much body type and race diversity. Truly the gayme of the year!
