Despite a stall by Apple on PopCap's new game, Unpleasant Horse, the new title form 4th & Battery is finally available on the App store. The "edgy" game -- formed out of an experimental effort by PopCap to release less refined games from its employees. The title, which is currently free, works on both the iPhone and iPad. 4th & Battery had launched its label earlier this month, but faced a roadblock from Apple after Apple rejected the title due to the "mature" content of the game. Unpleasant Horse features flying horses and a meat grinder. PopCap did not say what changes were made to change Apple's mind on the approval.
