Injustice 2 already has a big roster, but soon that roster will grow even more as the first of three "Fighters Pack 1" characters will be arriving soon
Red Hood will release on June 13th for Ultimate edition owners and owners of "Fighters Pack 1". For everyone else, he will be available on June 20th.
You can check out the full Watchtower stream showing off Red Hood on Netherealms official Twitch page.
Also be sure to check out my review of Injustice 2, which I personally consider to be Netherealms best game yet.
