Amazon might be working on a game console, after all. The online-retail giant on Thursday confirmed its purchase of Double Helix Games, the PC and console video-game maker behind Silent Hill Homecoming and the reboot of Killer Instinct for Xbox One, for an undisclosed amount of money. The deal “was for both talent and IP,”. Double Helix’s 75 employees in Irvine, California, will now work for Amazon.
