Details are a little sparse at the moment, but Amazon has reportedly acquired Double Helix Games, the gaming studio that developed Killer Instinct (which was published by Microsoft Studios). The acquisition is said to include the whole shebang -- talent and intellectual property (IP). One of the things that isn't known at this time is how much Amazon paid for the development.
"Amazon has acquired Double Helix as part of our ongoing commitment to build innovative games for customers," TechCrunch quotes Amazon as saying.
The acquisition adds fuel to rumors that Amazon is planning to launch its own gaming console. It's been an ongoing rumor, and more recently gaming site VG247.com said Amazon was working on a Android-powered console priced below $300 designed to compete with Microsoft, Sony, and Nintendo.
It should be noted that Amazon has its own game studio, which has been focused on mobile games like Air Patriots and Airport Mania HD Free. As for the future of Killer Instinct, a Microsoft spokesperson told Polygon that Microsoft Studios will continue work with a "new development partner" on Killer Instinct for the Xbox One, adding that "the franchise will remain with Microsoft Studios."
