Still can't play co-op. It gets stuck on the loading screen. Single player works fine, apart from the issue I mentioned before: early round spawn rate. It wouldn't be so bad, honestly, if not all of the zombies came out of the ground. There's barely anywhere to put my feet until I ope...

Spawn rates have gone through the roof with the 1.1 update. Not sure if it's intentional, but it makes even round 2 ridiculously hectic when all the zombies spawn in the first 20 seconds of the round.
