Activision are offering voluntary refunds to all US customers who purchased Guitar Hero Live on or after December 1st, 2017.
Customers may apply for a refund if they’ve purchased Guitar Hero Live in the United States between December 1st 2018 and January 1st 2019 (dates inclusive).
As long as a completed Claim Form is submitted before May 1st, 2019, and Activision can confirm that the purchase was legitimate, customers should be eligible for a full refund.
The reason behind the refund program isn’t explicitly stated, but it can be assumed that it’s due to the shutdown of Guitar Hero TV back in December 2018.
Guitar Hero TV, or GHTV, was a gameplay mode in Guitar Hero Live that allowed players to play along to themed channels. GHTV was an online broadcast channel that viewers could tune into and jam along with at will.
In June 2018, Activision announced the termination of GHTV and also the removal of Guitar Hero Live’s iOS app from the App Store. The servers shut down for good on December 1st, 2018.
The loss of Guitar Hero TV meant that Guitar Hero Live’s song catalog was drastically reduced, forcing players to only have access to the 42 songs on the game’s disc instead.
The blog post that announced the shutdown has now been replaced with information on how to claim a refund. However, you can view the original here, courtesy of the Wayback Machine.
