Lead a team of Marines on a new and dangerous type of mission. Descend into the dark and claustrophobic tunnels, fight the unseen enemy lurking in the shadows, avoid the horrifying booby traps, and emerge unscathed if you can!
Tunnel Rats is a standalone expansion to Purple Haze featuring three scenarios and brand-new mechanics and introducing tense melee combat. It offers a vastly different experience to the Purple Haze core game, and a variety of new events and weapons.
