Survivor is a multidirectional scrolling shooter written by Richard Carr for Atari 8-bit computers and published in 1982 by Synapse Software.
[1] The player controls a spaceship attacking a number of fortresses, attempting to destroy the fort's guns without being hit.
Survivor takes place on a scrolling map consisting of several areas walled off to form separate but closely spaced fortresses.
Since some of the fort guns can only be attacked from angles that demand additional holes be punched in the walls, the play can become hectic.
The Atari version allowed up to four players in a single mission, giving each additional user control over a different guns or weapons.
