## What is System Cleaner?

Bullet heaven meets base building inside a broken computer.

Fight waves of corrupted files while assembling a network of automated helpers. Dodge through the chaos yourself or build turrets, shields, repair systems, collectors, traps, and support structures that turn the arena into your own defensive machine.

Choose a cleaner and system level, stack weapons and upgrades, discover building combinations, and take on different run types and heat modifiers. Daily and weekly contracts use local records, so the entire game works offline with no account required.

Features:

- Fast survivorslike action designed for touch, controller, keyboard, and mouse
- Base building woven directly into each run
- Multiple cleaners, levels, run types, modifiers, enemies, and bosses
- Permanent upgrades, unlocks, a game dictionary, and local run records
- Adjustable screen shake, flash intensity, post-processing, vibration, hazard contrast, damage numbers, and audio
- Offline play with no ads, tracking, analytics, or account
