The game uses a side-scrolling view. Joe or Mac moves through several prehistoric stages, jumps across platforms, attacks enemies, and collects food and weapons. Weapons include axes, boomerangs, stone wheels, and other primitive projectiles.

Each stage ends with a stronger enemy or boss, and the player progresses by clearing the level rather than building a persistent character. Two-player cooperative play is associated with the original game, but the exact availability and input arrangement can vary by DOS release and configuration.

Keep moving and attack enemies before they can surround you. Use jumping attacks and projectiles to deal with enemies on different elevations, while saving stronger weapons for bosses.

Food restores health, so collect it when safe rather than rushing past it. Learn the timing of enemy approaches and avoid unnecessary close-range fights, especially near pits and other stage hazards.
