Omikron: The Nomad Soul publisher Square Enix is giving the game away on its online store to celebrate the life of David Bowie, who appeared in the project.
The offer is available for one week, from today through Jan. 22, for the Windows PC version of the game. Omikron is listed as free in the European store, but visitors to the North American store will have to enter the coupon code "omikron" at checkout in order to get the game for free.
Omikron: The Nomad Soul is an adventure game developed by Quantic Dream; it was the first project from the David Cage-led studio. Omikron was originally published by Eidos Interactive on Windows PC in 1999 and on Dreamcast in 2000. Bowie appeared in the game and contributed several original songs to it; you can read more about his role in the project here. A few years later, he almost made it into Harmonix's Amplitude.
In an email to Game Informer yesterday, Cage discussed his first meeting with Bowie and his collaboration with the legendary artist, describing him as "a gentleman, a brilliant person, intelligent, simple and accessible, curious about everything and very far from the preconceived ideas one may have about what a rock legend should be."
Update: Square Enix's tweet did note that the offer is available only "while supplies last," and Omikron is currently sold out on the North American store, with the usual "add to cart" button grayed out as "waiting list." Customers can give Square Enix their email address to be notified when the game is back in stock.
Update 2: Asked about the stock, a Square Enix representative told Polygon that the company is "adding more now" and said the store "should be replenished shortly."
Update 3: Square Enix has refreshed stock on its North American store for Omikron, the company said on Twitter.
