i have only played the predator campaign so far but i loved it enough to play it on medium which helps with button prompts, then to play it again on hard, no prompts, i think the only thing i found really annoying is the fact that i could lure 4 marines to the same same spot 1 at a time to dispatch them,lol marines 2,3,and 4 never noticed their dead pals laying headless on the floor.
