Thief

Thief is an Apple II multidirectional shooter written by Bob Flanagan and published by Datamost in 1981. It is a clone of the 1980 arcade game Berzerk from Stern Electronics. Gameplay The game puts the player in control of a thief that must make his way through simple mazes, though there are no objects to actually steal. Each level is populated by stocky, possibly robotic guards that converge on the player, and which the player must either shoot or evade. See also K-Razy Shoot-Out Robon Robot Attack
