Originally revealed for UK retailers last month, the Superman: Red Son pre-order bonus DLC for Injustice: Gods Among Us will be available exclusively at GameStop in North America. As shown in the trailer above, the DLC pack includes Red Son-inspired alternate costumes for Superman, Wonder Woman and Solomon Grundy (who wasn't in the Red Son comic storyline).
The pack also includes 20 extra missions set within the alternate Red Son universe, which is not to be confused with Injustice's also-alternate universe. It'll be interesting to see if Injustice's Red Son missions are actually set in an alternate version of Injustice's universe, making it an alternate, alternate universe. Alternate. Alternate. Now it just looks weird.
