Mars Cars is a 1982 Apple II game produced by Datamost. The player moves a car to collect eggs while avoiding monsters. Getting touched by a monster results in loss of a life. Monsters are added to each level as time increases. The car is allowed to drive through and remove barriers, but monsters cannot. When all eggs are collected, the player can move the car to the warp area on the right side of the screen to begin the next level.
