Yes, Dotemu, Lizardcube, and Guard Crush Games have now officially unveiled a paid 'Mr. X Nightmare' DLC pack for the game. It adds new playable characters and a special Survival game mode, and even more content is also on the way in a separate free update.
The new trailer (up above) focuses on one of the three new characters coming to the game, Estel Aguirre, as well as offering a quick hint at the other as-of-yet unannounced stars. Formerly appearing in the game as a boss fight-style foe, Estel’s powerful slugs and spin kicks "dish out serious damage to anyone foolish enough to get in her way".
The new Survival mode is still somewhat under wraps, but we do know that it'll "challenge players to elevate and prove their true capabilities through special tests of skill". Players will also be able to build their own personalised fighting style with a new character customisation tool, and extra weapons, moves, and enemies are in the works, too.
Finally, the free update mentioned up above is designed for Streets of Rage 4's best players. The update will add a 'New Mania+' difficulty that's said to serve up a "brutal" challenge, although there'll also be a new training system designed to help you perfect your strategies.
No dates or pricing have been revealed for the DLC just yet, so we'll make sure to stay tuned for more on that over the coming weeks. In the meantime, let us know if you're feeling hyped for more Streets of Rage in the comments below.
