Wishlist the DLC on Steam here!

Streets of Rage 4 is receiving paid DLC: Mr. X Nightmare which is adding three new playable characters and a special Survival game mode later this year on PC, PlayStation 4, Xbox One, and Nintendo Switch.

A separate free update is arriving alongside the DLC on all platforms with additional content. Play as officer Estel Aguirre, one of Mr. X Nightmare’s three included fighters, as she goes off duty to join forces with the heroes of Streets of Rage 4 for the first time.
Formerly appearing in the game as an intimidating, boss fight-style foe, Estel’s powerful slugs and spin kicks dish out serious damage to anyone foolish enough to get in her way. Mr. X Nightmare includes lively new original music from Tee Lopes, a composer and arranger previously featured in Sonic Mania, League of Legends, and Monster Boy and the Cursed Kingdom among other titles.
