The prequel game, ftb2, is UTTERLY cheated online, and they're using a new engine, reportedly.
All of the cheats have been ported from a previous socom, which all started with socom 2. Without that game, the cheaters would have nothing.
Thus, if you have a new engine, you can't port, thus you won't have problems with cheating, for the most part. Plus, I'm more than willing they learned from zippers' mistakes when it came to exploits and made it utterly secure.
I really hope so, as this will probably be one of the few games I will play on the psp.
