Still, aside from some frustarating moments, the single-player campaign is well-paced and entertaining. You need to read your journal to figure out where you are, what you're doing, and why you're throwing so many damn switches. The story is compelling, but it's not actually intergrated into gameplay. Like Wolfenstein 3D (PC), its old school namesake, Tides challenges players with enemies' toughness and sheer numbers rather than clever artificial intelligence. But undead soldiers can't mend the chink in the Nazis' Aryan armor-ein Amerikaner with a surfeit of moxie can bring down the whole shebang. The Nazis' research on the occult yields an unstoppable army of zombies, gun-toting robo-hounds, and lightning-handed priests wearing stylish velvet clothes.
