I\'ve found no black cubes, and I\'m on my 4th run through the Story mode. They may only be found when playing on Hard difficulty...
I\'ve blown up almost everything. The 747, the blimp, the ferris wheel, the giant pizza guy-thing on the first level, various building and solid structures, and um....that\'s all I can remember right now.
Oh, and so I don\'t have to post a new topic: Has anyone unlocked any secret characters? I\'ve only found Yellow Jacket. Does anyone know where I can unlock the others?
