The roster of fighters for Injustice: Gods Among Us has grown today, as both Sinestro and Hawk Girl were revealed during the fourth week of Battle Arena Super Fights. They are currently matched up against Superman and Green Arrow, allowing you to vote on the winner.

If you're interested in the game and haven't put your money down on a pre-order yet, Amazon.com is offering a $10 credit on both the regular and collector's editions of the game, which is scheduled to release on April 16th.
