Unfortunately, Duke doesn't get along very well with Tiny. Fins, as the name implies, is a Marine. He is the only character that can handle the various boats encountered in the game. He also has the ability to stay submerged with his diving gear, surfacing only when an opportune target for his lethal and silent harpoon presents itself. So, when he's sober, Fins is a pretty dangerous guy, provided there's a lake or river nearby.
Inferno serves as the team's explosive expert.
He also enjoys booby traps and hand grenades and is the only character that can cut through fencing with the game's wire cutters. In fact, he loves running over Krauts with a captured cargo truck almost as much as mowing down enemy infantry with the mounted MG on a freshly obtained German half-track or tank. Spooky is a shifty Frenchman who has mastered the art of espionage, impersonation, and assassination. Given a German General's uniform, Spooky can often tie up enemy patrols in hours of red tape or position them so that the rest of the team can sneak in for an ambush. He's also quite agile with his Cyanide syringe and a .45 automatic.
