I played AVP 2, and the part where you burst out of the guy isn't playable; and you don't eat your way out, you sort of burst out...you know, like in the Alien movies. Of course, the sequence was pretty gory, but I like to go into pointless detail like that.
Of course, if Thrill Kill were to have come out, it would've been the goriest, what with the lewd acts with midgets on stilts, etc. I just love bringing up Thrill Kill; it's very weird, even to me.
