Fatal Error

Fatal Error is a single-player real-time strategy game set on the digital battlefields of a computer world under attack. As an anti-virus construct activated by the Motherboard, you use advanced programming and your TAC-AID companion to protect the Mainframe and fight the invading virus.

The digital invasion

For cycles immemorial, the Mainframe has shaped the existence of the Motherboard and her digital constructs. Now a sinister viral invasion is besieging it, and the Motherboard turns to an untested but powerful anti-virus construct: you. TAC-AID, or Tactical Artificial Intelligence Defender, accompanies you as you face the threat.

Build your forces

You choose between two sides, Anti-Virus and Virus, and command over a dozen units and structures. Multi-tiered research tech trees support tactical management alongside fast-paced battles.

Campaign and skirmishes

The single-player campaign tells the story of the invasion. Skirmish mode offers multiple maps, with adjustable A.I. difficulty and team composition.

Create maps

A full-fledged map editor lets you make custom maps. The game uses retro-style graphics inspired by classic RTS games from the 1990s.
