Harmonix has confirmed in a blog post, that after 8 years of post-release content DLC releases for Rock Band 4, one of the last remaining musical instrument games from a bygone era, will no longer be hosting new songs after next week’s DLC releases drop. They also confirm that other online services will continue as normal, including Rivals season.
The company has since released Rivals and the VR experience for Rock Band, and has since created other games such as Fuser and Fortnite Festival since the Epic Games acquision.
