Wolfenstein: The New Order
I'm really enjoying Wolfenstein: The New Order from Bethesda.
This is an honest attempt by Swedish developer MachineGames to reboot the series but keep intact the twitchy gameplay of id's original game (Wolfenstein 3D), along with its implausible protagonist, "B.J." Blazkowicz.
They've fleshed out the story and the characters (at least as fleshy as an Indiana Jones movie). It's got an actual plot that involves an alternative 1960's where the Nazi's won World War II.
New Order is an unabashedly adult title, oozing a Grindhouse corniness along with gratuitous sex and violence. And the gameplay is fluid like no modern FPS has been before. The enemies move fast, stumble, slide, and make spectacular falls just like movie stuntmen.
The New Order skates on the razors edge of taking itself too seriously and being a parody but it's super fun to play.
