Asteroid Impact is a point-and-click style video game where subjects use a cursor to collect crystal-shaped targets that are displayed at different locations while avoiding asteroids that bounce around the screen. All aspects of the game can be manipulated with a high level of experimental control. The stimulus records all game events with 16ms temporal resolution, which are then output as a .csv file. Asteroid Impact is written in Python, is platform agnostic, and can synchronize with TTL triggers. The game features an open source license (CC BY-SA 4.0), and is freely available to the research community. Those wishing to further develop Asteroid Impact or download experimental releases can do so on Github.
