GameStop is reported to be returning stock of Deus Ex: Human Revolution on PC because of an included voucher for a free OnLive copy of the game.

Yesterday it was reported that the store was removing the OnLive codes included in the PC version of Deus Ex: Human Revolution, before returning the game to store shelves. However, later in the day GiantBomb received a GameStop internal memo indicating that Deus Ex PC stock was to be returned after it was decided OnLive was in direct competition to the retailer's upcoming streaming service.

"At this time please pull all Regular PC editions of Deus Ex: Human Revolution and place them in your backroom. These will be recalled at a later date," read the note. "As GameStop is developing a streaming service in our Spawn Labs Cloud Computing Division, the coupon that was included is for a competing service. We are returning all copies of the PC regular edition to the vendor in agreement with Square Enix.

"Any unfulfilled reserves of the Regular PC Edition should be taken care of with the inventory set aside in your backroom. Please honour any returns with a receipt."

Square Enix offered the following statement: "As part of Deus Ex: Human Revolution's boxed offering on PC, Square Enix included a third-party coupon. GameStop was not made aware of this inclusion and Square Enix respects the right of GameStop to have final say over the contents of products it sells and to adjust them where they see fit in accordance with their policies.

"Square-Enix invites gamers who want to purchase the PC version of Deus Ex: Human Revolution without additional coupons to buy the game at any one of over 4,000 GameStop stores in North America or purchase a digital download copy online from"
