Bugs in games - everything. Halo developers have released an open-source AI autopilot agent for game testing. It works simply: write "check the craft" or "kill the boss while maintaining more than 20% health" - the agent reads the project code, launches the game, plays and collects a report. At the same time, over time, the agent adapts - he aims better, dodges and picks up a weapon. Supports Unreal Engine 5, Unity 6 and Godo 4 on Windows and macOS, saving project knowledge between launches. The dream of all indie developers is here.
