My friends and i think its great!!
Upgrading the weapons is good something not seen in a wolfenstein game, NPC animations are always good for a laugh too when watching them spill blood from their neck as they die. Have yet to play multiplayer though as single player is so fun :)
Only thing that stops it from a 10 from me is that although the Thule Medallion powers are cool theres nothing else new or mind blowing that has been brought to the genre, never the less a great game.
And is it just me or does BJ look a lot like Kurt Russell... Wolfenstein movie anyone??
