Ra Ra BOOM puts up to 4 players in a co-op battle on a future version of Earth. Here, a rogue AI commands legions of robots that have taken over the planet. It's up to a team of ninja cheerleaders to confront this mechanical threat. The gameplay combines beat em up and shoot em up elements. You'll have to break through hordes of enemies, moving through chaotic locations of a ruined world, from swamps to sewers.
