DEMON SIEGE Build 24899977

About The Game

Demonic hordes and infinite stacks of upgrades collide in DEMON SIEGE, a compact retro inspired FPS from The Jank Factory, a solo developer who built the game as both studio and publisher. This is a bullet heaven shooter in the spirit of classic boomer shooters, arcade score chasing, and modern survivor style action. Every session is fast, loud, and focused on momentum.

The game runs on the old school EasyFPSeditor engine, originally designed for much simpler Wolfenstein 3D style games. Instead of chasing modern graphics, the project embraces that retro DNA and stretches the technology far beyond its intended limits. The focus stays on satisfying combat, addictive progression, and overpowered builds.

Two modes carry the experience. A short and sweet Story Mode gives the campaign its shape, while the Endless Mode invites you to play until you break the game with how powerful you get. Fight through the hordes, earn gold, and buy upgrades from vending machines between waves. Ammo, skills, health, and guns all wait behind the glass every round.

The build crafting is where the absurdity lives. Every 10 kills brings a randomly selected upgrade, and every upgrade stacks without limit. Soon you move so fast your boots set the terrain on fire, leap across the map, and fire walls of bullets with every shot. A killstreak announcer calls out your score and pays bonus gold for high performance.

Progress follows you through every level, and nothing resets after a stage, so by the end you become unstoppable. Level ups, skills, and weapons all ride along from one stage to the next. The design rewards long runs and bold greed, pushing you to see how far the systems can be stretched. DEMON SIEGE is a small game with a big appetite for chaos, built for players who want their power to keep climbing.
