So, I started playing Metal Gear Online last night...
 

It's hella fun. There does seem to be a lot more cheating / people exploiting shit than other online games tho. Stuff like guys looking in your basic direction, BOOM, instant headshot. I keep getting CQC'ed from 1/2 - 3/4 screens away too. So, does anybody else here play it? Post your username if you do, just so I know who to look for ;).
