Injustice 2's first DLC fighter, Red Hood, is now available for early play for folks who purchased the ultimate edition, ultimate pack or fighter pack 1. In case you have trouble getting him to show up in game, there’s a guide over on the game forums. Or just jimmy him loose with a crowbar.
Before he became the Red Hood, Jason Todd met a grisly fate at the hands of the Joker in the iconic A Death in the Family storyline, including a horrifying beating with a crowbar. At least now in Injustice 2, Jason can enact some justice (both poetic and physically) against the clown prince of crime as payback.
