Injustice: Gods Among Us sold 424,000 copies in the United States, only April release to sell over 250,000 units
This game is amazing. Sorry to all the "Capcom or nothing" d*ck riders out there but Injustice is just as good as any Capcom game available.

Injustice combo roundup featuring Solomon Grundy 73% combo, Sinestro 69% trait combo, Flash combo guide and Nightwing combos
I found an awesome 84% Grundy combo. Costs 4 meters though and requires MB swamp gas and regular swamp gas so extremely unlikely to ever work in game.
