Invaders

Invaders is an unofficial conversion of Space Invaders for the Xerox Alto. The player uses the mouse to control the tank at the bottom of the screen moving left and right with the left and right mouse buttons and using the middle mouse button to fire. The player can hide beneath four bunkers that will take damage if hit by the player or aliens. The aliens will slowly make their way down towards the surface unless destroyed by the player. Periodically a UFO flies past the top of the screen which can be hit for additional points. Points are scored in a highscore table available over the network.
