If the twist is what I said earlier, than there is no "twist." You wake up in the lab, they explain to you where you are, etc. and you have to cooperate for them to extract the memory DNA from your badass ancestor(the dude you play as, who looks just like you in the present). I could get more into it, but I'm not. Yeah, it's not a twist. It's out in the open right when the game starts....even though there may be one you know about at the end of the game. In that case, SHUTUP
