Playing another similar game now, but on the Xbox 360, it's Warriors Orochi.
I'm hoping in that game, I can unlock Lu Bu, which I am slowly working on. I mean, I managed to complete the Shu story line with my character at level 99 to take on Orochi....man was he a pain in the arse to kill, especially when the guy who wasn't allowed to die in that missions, was also helping me take on Orochi....and he was able to die more easily than myself.
