I vaguely remember playing that game and not enjoying it.
Something about a dead guy possessing his squad mates? And demons and stuff?
I seem to recall really struggling and ultimately relying on a single character and funneling all enemies into a single choke point where I could take them on one by one.
This was a long time ago and really is hazy at best on my mind. I'd be morbidly curious to give it another shot today just to see what was up.
