The DLC is compatible with all characters currently in the game, increasing Marvel Cosmic Invasion’s roster to 19 playable fighters once the pack is released.
Tribute Games and Dotemu also stated the DLC will include a brand-new game mode; however, the developer is not disclosing specifics about that mode at this time.
