Xbox One users can get a digital version of Lost Odyssey, which is backwards compatible, free of charge by downloading a free avatar t-shirt.

The free t-shirt—available here for men and here for women—includes a free Xbox One digital entitlement to Lost Odyssey. The game will appear in your “Ready to Install” queue after downloading the t-shirt. The t-shirt and entitlement will only be available to download until November 30.

Currently, this is the only way to get Lost Odyssey digitally, as the game is not available for purchase on the Xbox Games Store.

Update 9:15 p.m.: According to Xbox Live’s Major Nelson, “This was a test that slipped out. There are no plans right now for it to go live.”
