TowerFall, which is known for being the Ouya's killer app, will be making the transition from console exclusive to multiplatform when it releases on PS4 and PC early next year with a new name TowerFall Ascension. TowerFall is a multiplayer action brawler game that has been favorable compared to Super Smash Bros. and hailed as one of the best games of 2013 despite only having been played by a (very vocal) minority. The game also received a new trailer to show off new features, including a new co-op mode.
TowerFall is one of the few games I had no chance to play this year because I don't have an Ouya. Lucky for me I'm getting a PS4 today and will be picking this up the day it comes out. Guess I better get some more controllers.
