Tunnel Rats: 1968 is a first-person shooter developed as a tie-in for the Uwe Boll film 1968 Tunnel Rats. It has seven levels. Booby traps are located throughout the game world; trap doors are disarmed by locating an actionable point used to deactivate them. Tripwires are disarmed in a minigame where the player must stop a sliding bar within a specified zone; stopping within a narrower target also allows the player to collect the grenade that was part of the mechanism.
