The Socks-Out: Sleeping is mission impossible.

[Inferno.]

I'm really enjoying it. If you've played U2, then the first one feels a little bit... clunky. But otherwise, it's a pretty solid game, in my opinion.
Just made it out of the U-Boat Dock. I think I only died twice, but it took me about twenty minutes to clear it. A lot of "three steps forward, fifty steps running back being chased by zombie demon things"

I've played them both, I played U1 about a month or two before U2 released and I picked up U2 on launch. I played through them both twice, U1 on normal and hard, U2 on normal and easy (mopping up collectibles).
