Galactic Invasion

Galactic Invasion is a port of the classic arcade game Galaxian to the Bally Astrocade.

This space shooter supports up to four players, with players taking turns firing on a descending alien horde. There are nine levels of gameplay difficulty available, with more enemy bombs and faster enemy speeds at the higher levels. The number of bases (lives) the player has is also configurable at the start of the game, from 1-9.
