The Steam store page has been updated with our new launch trailer! We just finished personally testing every purchase, and even though there's a big scary warning if you have the beta installed that incorrectly says you already have the game and won't receive additional copies, Steam's working to fix that. Rest assured that everything DOES work and the preorders go through without any problem.
If you've been waiting to preorder, now's a great time to pull the trigger!
