So if you link Injustice on the console with Injustice on the iPad, you can unlock a few cool costumes. One of them is the Batman Beyond costume, but it's done through such a bizarre challenge that I almost think it was designed to be a "let's game the system together" thing. You have to play an online game, do all three transitions in the Metropolis stage AND win the fight. (Typical ex-Midway employee behavior, but what are you gonna do?) Doing this unlocks the Batman Beyond skin on the iPad version, which should unlock it on the console version as well (the criteria for that is "get any Batman card in the IOS version"), I just don't see it happening unless both parties are down to game the system in this way. Doing ONE transition against humans is hard enough, let alone all three on a level that's so large, you have to walk to transition points just so your opponent's health holds out.
Anyone up for that on the PS3? My gamer tag is Foenix654 (because you can't use a city name on the PSN, even though I didn't think of Phoenix the city when I chose the name... anyway), hit me up if so. I'll gladly be your punching bag if you'll be mine.
