Don't get me wrong it looks awesome. The only problems I have is the annoying guitar tune whenever you get what looks like a challenge. Also guns dont have alot of recoil although I understand it is a beta so it may be changed prior to release date.
So looks like SR71 only lasts 30 seconds and only makes enemies dark red if they are shooting, pretty bad for an 8 killstreak if you ask me - I was getting excited about this one.
