CCG writes – “At the very least, owners of Synth Riders should grab the free to play songs. Muse fans and people who enjoy 80s and 90s synth music should definitely pick up the entire DLC pack. The Alternate Reality experience alone is worth the purchase. If you really enjoy the music and are curious about the first Synthwave Essentials, I couldnt find it anywhere so Im not exactly sure what this is a sequel to.”
