RWBY: Amity Arena

User summary: A real-time battle featuring the heroes and villains of RWBY! Players deploy units with a variety of abilities to attack the opponent's towers. Victories gain you 'cards' and money that you can use to level up your units and gain new units. The game is broken into multiple arena levels, so you usually play against opponents of around the same level. The game has IAPs and loot boxes. Some cosmetic upgrades are only available for purchase, but all units can be obtained in free play. The game also has a single player mini game where you control one hero fighting hordes of enemies in a 3rd person fighter format.
