So this is quite a frustrating game, but my love-hate relationship will have to last a bit longer. At least if I can get past Mahattan as so many others have tried. I actually eventually completed ALL tasks, but I'm still not gettin' a new mission. After I take out the main Chedaki base I'm just greated back at the Manhattan base and left with nothing to do. Any suggestions? I'm currentling driving all over the map looking at the scenery.
