Bullet heaven meets base building inside a broken computer.

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.

Each run can lean toward active bullet-heaven movement or a growing base-building setup. Keep moving, stack weapons, dodge through the chaos, and clear the screen yourself, or place shooters, shields, traps, collectors, repair helpers, boosters, teleport pads, and more.

Replayability is built around optional heat modifiers, fixed-seed daily and weekly contracts, local records, milestones, map objectives, selectable run events, and unlockable branch evolutions.
