Spectre is a video game for the Apple II written by Bob Flanagan[2] and Scott Miller and published by Datamost in 1982.[1][3]
Spectre is a Pac-Man variant with a goal of collecting dots while avoiding "Questers." The player navigates the maze with a 3D view on the left side of the screen and a top-down representation on the right.
A Spectre advertisement reads:
You're marooned between the stars, and the deadly Questers are swarming through the space ports to destroy you. Think fast, act faster if you hope to survive! Only Spectre brings you a fantastic 3-D maze action ... and a special enemy locator-screen[3]
