I'm kind of surprised i'm the first one to post here. Still, here we go. I'm at the part where i shot out the engineer from the missile tube, and not i can't do anything after that. My friend plays in easy mode and he said he just used the lever to open the hatch for critter to move in. With me however who plays on hard mode can't pull the lever. When i right click the lever Nate says something like "I just have to try this" and then he doesn't do anything, but when i left click the lever he says something like "If i and critter are ever to get away from here i better not" something like that. I've been everywhere, and i can't combine anything, can't speak to anyone, nothing.
