Same terrible time loop as part 1?
I never figured out the first game. It seemed like you had an hour or two to play the game, then it would automatically restart. I didn't have an HD tv at the time thus couldn't read any of the mission text, so couldn't really progress. So I just ran around and killed lots of zombies. Then the game would reboot and I got to start all over again.
The wiki page for part 2 says it will have the same time mechanic. I'd though they had enough feedback from players who hated this aspect to leave it out of the sequel. Evidently I was wrong. Hopefully this information won't be accurate, but the trailers I've watched seem to have timers.
