That just happened!!! Ã‚Â The online retailer site has just acquired Killer Instinct developer Double Helix Games. TechCrunchÃ‚Â got confirmation directly with Amazon, “Amazon has acquired Double Helix as part of our ongoing commitment to build innovate games for customers”. It goes on to say that all 75 Double Helix employees will stay on during the transition. As for what this holds for Double Helix Games, or their latest game Killer Instinct exclusively for the Xbox One, its all speculation.
