If you've held out on buying Rock Band 4 digitally in the past decade, you have less than a week to nab it. Harmonix producer Kyle Wynn shared news of the impending delisting on the official Rock Band Discord server, as spotted by Wario64 on X. Rock Band 4's base game includes 65 songs, and DLC support, which included the Rivals expansion, lasted until January 2024. For instance, Rock Band 3 was delisted in October 2015, five years after its launch. Harmonix has been under the ownership of Epic Games since 2021, leading development of the Rock Band-like Fortnite Festival game mode.
