As Jack, you navigate the dense, prehistoric jungles in a first-person perspective. The game lacks a traditional Heads-Up Display (HUD) or map, forcing you to rely on visual cues and audio to survive. Resources like ammo are scarce, requiring you to manage supplies carefully and often use primitive spears or fire to ward off predators.

To accommodate the handheld hardware, several changes were implemented compared to the PS2 or Xbox versions:

An exclusive Ad Hoc multiplayer mode was added, offering both Cooperative and Competitive options for two players. While players cannot see each other on screen, their actions directly affect the other's game world (e.g., killing a monster in co-op helps your partner, while doing so in competitive mode makes the enemy stronger for them).
