Space Cowboy is a video game written by Scott Lamb for Atari 8-bit computers and published by Avalon Hill Microcomputer Games in 1983.

[1] Space Cowboy is a game in which the Space Cowboy maneuvers along a walkway shown in three-quarter perspective, avoiding blasts from wall-mounted lasers.

[2] Bill Wallace reviewed Space Cowboy in Space Gamer No.

[2] Wallace commented that "The action is idiotic, wooden, boring after only a couple of minutes of play.

If you'd never seen Zaxxon the three-quarter perspective would be interesting, though it doesn't really contribute to play.
