Great. A favorite.
An awesome brawler. The medals appear to be still bugged, since the only ones i appear to have on this page are "diplomatically challenged" and "the eventuallyending story", while in game i got the little pop-up thingy for being awarded many others.
Anyway, the game is good, and i didn't find any problem while playing.
It's rather annoying in two player mode on a single keyboard, and it could do with a full screen mode (the expand button really doesn't make it, because in my browser part of the game-screen is cut out, maybe it's because of my resolution, though).
The challenges are a nice addition to the beat'em'up. I always like them in my games. They are not very rewarding here, though, and plain easy after completing all the stories. Maybe some unlockables could have been linked to objectives rather than score.
The Convict ending is hard, but not impossible, at least on normal difficulty. I still haven't tried on OMFG. Then i'll move to survival mode, i guess.
