The beat ’em-up, which has sold an impressive 2.5m copies, is also getting a new mode and new customisation options. Estel Aguirre is one of the three new playable characters. She appeared in the game as an intimidating, boss fight-style foe. The video below shows Estel as a playable DLC character. There’s also a hint at the DLC’s two other characters yet to be revealed. Mr. X Nightmare also introduces a new Survival mode. Expect more on that soon. There’s character customisation, new moves and new weapons, too. Mr. X Nightmare includes 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. Meanwhile, Streets of Rage 4 is getting a free update that adds the New Mania+ difficulty, an in-depth training system, and fresh colour palette options. Our Martin gave Streets of Rage 4 a coveted essential badge in Eurogamer’s review. “Glorious artwork and a fan’s eye for detail combine for a sequel that manages to best its forebears,” he wrote. The Mr. X NightmareDLC is due out later this year on PC, PlayStation 4, Xbox One, and Nintendo Switch.
