Our take on FATAL ERROR - RTS

Rather than using a historical, fantasy, or military setting common to many strategy games, it places the conflict inside an abstract computer world. The opposing sides are Anti-Virus and Virus forces, and the campaign frames the player as an activated digital construct defending the Mainframe.

What is FATAL ERROR - RTS?

Command an anti-virus construct defending the Mainframe from a viral invasion in a real-time strategy game set inside an abstract computer world.

Choose between two opposing sides, Anti-Virus and Virus, and manage more than a dozen units and structures across a single-player campaign. Research progresses through multi-tiered technology trees, while skirmish mode provides multiple maps, adjustable AI difficulty, and configurable team composition. A built-in map editor supports custom battlefields. The game combines fast action with tactical management and uses retro-style graphics.
