I played a fair chunk of it along with my friend who bought the game. It was fun, but things got old as the game dragged on. Especially since it is the same thing every time, only slightly altered in scenario. Not to mention that the story, while interesting, was boring as all hell in delivery. I want cut scenes where things happen, not me standing there staring at fixed camera angles for five minutes while the characters do nothing but blab on and on.
Repetition is the name of the game, though it was still fun and I really liked the one guy you have to kill
The crazy Teutonic Templar with the demon helm. Though I kept falling in the water trying to kill him which really *edited*ed me off.
