Alien

Alien for the Atari 2600, based on the movie of the same name, is similar to Pac-Man (and oddly, Frogger).

Overview

Drawing on Pac-Man, if not outright copying it, this game features vaguely Alien-esque enemies and equips the player with a flamethrower. The labyrinth stands in for the corridors of a spaceship, and this at least provides a decently claustrophobic atmosphere.

Completing a level, by collecting all the eggs and killing the aliens, takes you to a bonus level fairly reminiscent of Frogger.
