I'm playing Return to Castle Wolfenstein (RTCW). It's an amazing game, IMO.
I'm on the level where you have to face Deathshead's "Ubersoldat" at the moment. I watched a walkthrough where someone managed to get away from it, kill all of his underlings, and blasted Deathshead using a Panzerfaust. I can't stop laughing...XD.
