Have you tried verifying the integrity of your game's files?Anyone having a problem with the game starting up after the patch? I've restarted a few times, made sure steam was up to date, etc. The game is currently stuck on the Scorpion MK11 image that pops up after hitting Play in steam.
Hmmm.... if you haven't already, reboot your PC, and then fire up Steam and see if it shows up. If it doesn't, I'd try doing a File Verification.Supposedly another update popped up that's 450mb and people are reporting the game working after downloading it. I can't seem to get the update to show up.
