CCG writes – “Synth Riders has been releasing DLC packs with various music genres including synthesizer, swing, and cyberpunk. The Adrenaline pack mixes things up by adding high-energy guitar music. Owners of the base game get to benefit from these DLC packs by getting three songs for free. Better yet, you dont have to own the DLC expansion to do multiplayer battles on the paid songs. As long as the host owns the song, anyone on any platform can battle them.”
