DEMON SIEGE Build 24899977 (upd.25.08.2026)

DEMON SIEGE is a compact retro inspired FPS and bullet heaven game built by The Jank Factory, a solo developer acting as both studio and publisher. The concept mixes classic boomer shooter action with arcade score chasing and modern survivor style progression. It is a fast experience that never asks for a long evening of your time. Sessions stay short, loud, and focused on building absurd power.

Two modes shape the experience. Story Mode offers a short and sweet campaign that takes around 40 minutes to an hour to beat. Endless Mode removes the finish line and invites you to play until you break the game with how powerful you get. The studio recommends starting with the story and moving up when you feel ready.

Under the hood runs the old school EasyFPSeditor engine, originally designed for much simpler Wolfenstein 3D style games. The project embraces that retro DNA and stretches the technology far beyond its intended limits. Instead of modern graphics, the focus stays on satisfying combat, addictive progression, and overpowered builds. The visuals stay raw on purpose, and the friendly style keeps the action readable even when the screen fills with demons.

Every 10 kills presents a randomly selected upgrade, and every upgrade stacks without limit. Gold earned from the demonic hordes feeds vending machines that sell ammo, skills, health, and guns each round. Soon the hero moves so fast that boots set the terrain on fire, leaps across the map, and fires walls of bullets with every shot. A killstreak announcer rewards high scores with bonus gold.

Nothing resets between stages. Level ups, skills, and weapons follow you through every level, so the power curve never dips and by the end you become unstoppable. The whole package was created without a single AI generated asset. DEMON SIEGE is a small retro shooter with a big appetite for chaos, made for players who love watching numbers explode.
