Good port, but could have used some work
There is good news, however. The entire game was ported from the console. This mean the entire story and online multi-player. If you have a wireless internet connection, you can go online and play multi-player. There's even PSP specific bonuses. 4 extra players to unlock and 9 bonus missons.
The strangest part of all is that the graphics are actually worse on PSP than on the consoles. The characters actually seem OVER sharpened. to the point that the graphics suffer. This should be the opposite for a hand held with a much smaller screen.
