WARNING TO ALL OF YOU THINKING OF BUYING THE 360 VERSION:
THE GAME IS BROKEN.
I just encountered a serious bug as described above. I deleted my game completely and re-downloaded it and it still doesn't work anymore.
I can enter games but my guns don't shoot, i cant switch to items or guns, i cant open the items menu, nothing. And i have 25 minutes left of trail time.
Ive cleared my cache, Ive deleted my trail and re-downloaded it and cleared my cache again but i cant use any of my guns anymore. Its absolutely ridiculous.
Be careful if you buy this crap on 360, i warned you.
