The game uses a side-view perspective and sends Joe or Mac through horizontally scrolling prehistoric stages. The objective is to reach each stage's end, defeat enemies, and overcome a boss.

Players move across platforms, jump over hazards, collect weapons, and attack enemies at close or ranged distance. Different weapons change the attack's reach and behavior. Two players can cooperate, and progression follows a fixed sequence of themed areas with boss encounters.

Use the longest-range weapon available when approaching groups, especially against flying enemies and bosses.

Keep moving through open areas, but slow down near pits and enemies that can attack from above. In two-player mode, coordinate movement so one player does not scroll the screen ahead of the other.

Learn boss attack patterns rather than trading hits. Preserve lives by avoiding unnecessary fights when the route allows safe passage.
