GameStop has apparently sent another message out to its retail locations, this time asking all of its stores to pull any PC copies of Deus Ex: Human Revolution off of its shelves, and place them in the backroom, eventually to be returned to publisher Square Enix. This all after this morning's news that GameStop had directed its employees to pull coupons out of the boxes for the OnLive streaming service.

The latest email confirms that GameStop is indeed working on a competing service with its acquisition Spawn Labs, and that because of an "agreement" with Square Enix, all of the game's copies will be recalled back to the publisher. The one exception is reserved copies, which will still be honored for purchase.

GameStop has also pulled the PC version of the game from its website, though the console versions are still for sale. Joystiq has confirmed with local stores that the memo was received and copies were being pulled. We're also contacting GameStop corporate for an official statement on the matter.
