Malware Buster
SteamAbout Malware Buster
The system is severely infected. You are the only cure.
MalwareBuster is a fast-paced survivor-like Roguelite game. Playing as the core antivirus software inside a compromised PC, you must stand alone against tsunamis of Trojans, worms, and malicious computer viruses. Only by constantly upgrading and power-up yourself with specialized items can you survive this digital storm.
Core Features
•
Ultimate Horde-Slaying Thrill: Face off against thousands of malware entities within a retro-styled virtual grid. Experience the pure joy of tearing through enemies and deconstructing them into data shards in the blink of an eye.
•
Deep Build Synergy: Power up your character by acquiring items with vastly different effects. Whether you want to unleash a projectile-focused bullet storm, a screen-wiping AoE (Area of Effect) build, or an immortal tank setup relying on heavy armor and life-steal—anything is possible. Every single run is a completely fresh experience.
•
Meta-Progression: The end of a battle is not the end of the journey. Use the Talent Coins earned from your runs to unlock permanent upgrades, gradually transforming your antivirus software into the ultimate weapon.
•
Push the Limits: As the waves progress, viruses will continuously evolve. Test your micro-movement reflexes and build choices under intense bullet hell and relentless encirclement.
