System Cleaner Demo

System Cleaner is a survivorslike action game set inside a broken computer.

You play as a tiny cleaner dropped into a messy digital world full of corrupted files, glitches, errors, and forgotten junk. The job sounds simple: clean the system. The problem is that everything in it wants you gone.

Fight through waves of hostile programs, collect upgrades, place helpful buildings, and turn each run into your own little cleanup machine.

Clean Your Way

You can play System Cleaner like a bullet heaven: keep moving, stack weapons, dodge through the chaos, and melt the screen yourself.

Or you can lean into the building side. Place shooters, shields, traps, collectors, repair helpers, boosters, teleport pads, and more. Build a setup that fights, earns, protects, and grows while you focus on staying alive.

Some runs feel like pure action. Some feel more like a base builder. Some turn into an incremental mess of helpers doing more and more of the work for you.

A Broken Little World

Every folder is a mess. Every error has teeth. Every upgrade gets you closer to turning the system back into something usable.

Or at least something a little less broken.
