System: Reboot

Build a PC. Deploy firewalls. Crush every virus.

System: Reboot is a tower defense game set inside a computer: on a motherboard you build yourself. Place protocol towers along circuit-board traces, hunt raid bosses for blueprints, and upgrade 9 hardware components to push your system to the limit.

TWO MODES, ONE GOAL

TOWER DEFENSE: THE MOTHERBOARD • Build across a 3×3 sector grid with PCB circuit-board aesthetics • Place firewalls along copper traces to stop endless virus waves • Manage your power budget: every tower draws watts from your PSU • Earn passive Hash income, even while you're away • Overclock for 4× rewards: but the threats multiply too

BOSS ENCOUNTERS: THE ARENA • Fight 4 raid bosses with unique multi-phase mechanics • Rogue Process, Memory Leak, Thermal Runaway, Packet Worm • 4 difficulty levels from Easy to Nightmare • Defeat bosses to unlock protocol blueprints • Joystick controls with auto-targeting combat

8 PROTOCOLS: TOWER & WEAPON IN ONE Every protocol works as a firewall tower AND a boss weapon. Upgrade once, power up both modes. From the common Kernel Pulse to the legendary Null Pointer — compile your arsenal and find your playstyle.

BUILD YOUR RIG • Upgrade 9 components: PSU, CPU, RAM, GPU, Storage, Cache & more • Unlock new sectors by defeating Super Virus bosses • 5 CPU tiers for massive income multipliers (up to 16×) • Merge identical towers for star upgrades (up to 8× stats)

WHEN THINGS GO WRONG Hit 0% system efficiency and everything freezes. Pay Hash to flush memory or survive the Manual Override mini-game for a full restore. Failure becomes gameplay.

• Dark terminal aesthetic • Idle income: earn Hash offline for up to 24 hours • No internet required: fully offline • Procedural audio: every sound is synthesized in real time • English & German localization
