Other levels besides the first two??

You've actually seen some of the first three Acts already, and we probably won't be revealing too much more than what we've already shown. We really want to try to keep as much a surprise for you when you play through the game the first time as possible. We will be announcing all of the game systems though before beta, so there are a few things left as far as reveals go. While beta will obviously be a lot of fun, should you get the chance to get in and help test, it'll only be a small part of the whole game. Some people want to know everything, but we're really trying to preserve the surprise and wonderment (that we hope will come with exploring Diablo III) as much as possible.
