Most modern first-person shooters are so very serious. They feature a whole lot of brown environments and gruff characters, but never have enough archways into alternate universes. Well, if you're in the mood for an FPS with a glint in its figurative eye, Wolfenstein is a good way to stave off the forces of evil without the in-game grumpiness that usually accompanies such endeavors. This sequel to 2001's Return to Castle Wolfenstein is a worthy addition to the series and a fun romp in its own right. The game won't set your world on fire; it occasionally stops feeling old-fashioned and starts feeling just plain old, and a number of flaws are woven throughout the gameplay's very fabric. Some awesome boss fights and memorable combat sequences prevent Wolfenstein from falling into a rut, however. Besides, you're not just fighting Nazis--you're fighting magic Nazis that conjure force fields and fly around with jetpacks.
