There are a ton of playable characters in Tekken Tag Tournament 2 for the PS3, Wii-U, and Xbox 360. There are even some characters that aren’t available in the Arcade version.
Some of these characters are DLC only, most of which should have come with a pre-order of the game, but will eventually be purchasable either way.
