Good news! There's Streets of Rage 4 DLC on the way. Bad news! There's no ETA on when we'll get it just yet.
Posing a hypothetical question on its own Twitter feed, developer Dotemu responded to a question about additional content by confirming DLC is on the way.
"YES, we will [add new content] but there is no ETA," the developer said. "You guys are awesome and deserve the best so give us time to do things right."
