The DC fighter is less than a month away from release, but NetherRealm Studios isn’t just going to stop working on the project once it ships. Warner Bros. Interactive has announced today that Injustice: Gods Among Us will have an optional season pass that will include four unannounced downloadable characters, along with some skins for existing heroes and villains.

Normally it’s difficult to recommend season passes considering the quality in recent games have been questionable, but they’ve mainly been twenty to thirty dollars. Injustice: Gods Among Us’ season pass will be tagged at a reduced price of $14.99, making that five dollar difference all that more tempting. Who will these fighters be? Only time will tell.
