TowerFall Ascension, a significant update to Ouya's Towerfall, will be "exclusive" to PS4 and launch in early 2014. Towerfall is also scheduled for PC, but we're going to need to get some clarification if that version is a port of the Ouya game or of this Ascension version planned for PS4.
"Brand new levels, we got 50 new levels coming. All kinds of new modes," said SCE America VP of Publisher & Developer Relations Adam Boyes on tonight's Spike PS4 launch special.
Developer Matt Thorson writes on the PlayStation Blog, "50 new versus levels, 4 more playable archers, an all-new, twelve-player cooperative Quest mode, 6 additional power-ups, and more. We've even gone back and refined everything in the original release. It feels like a whole new game."
