Apparent MVP achievement bug
I did a search for this but couldn't find anything, so I'm posting a new thread. Basically, there appears to be a bug regarding the MVP achievement in that anyone playing as a Nazi is unable to get it (or at least, was unable to get it when I was boosting with a group for it). As such, it seems you must be on the Allied side for it to unlock.
Currently boosting on 360: Battlefield Bad Co., Halo Wars, Ninja Gaiden 3: Razor's Edge, Quantum of Solace, Riddick, Ultra SF4.
