We are hard at work building our museum--cataloguing thousands of computer artifacts and crafting a rich, immersive journey through the history of computing. While we continue assembling this extraordinary collection, enjoy one of our favourite classics. Every time we acquire a new computer, this is the very first game we load up: Space Invaders. Dodge incoming fire, outmaneuver the alien swarm, and defend the last orbital city. Desktop controls: move with the arrow keys or A/D and fire with the space bar. On touch screens, tap the on-screen controls below the cabinet to steer and shoot.
