Double Helix seemed like a strange choice to reboot a beloved franchise like Killer Instinct — it’s a studio that had previously worked on licensed games based on GI Joe and Battleship. Yet, despite this modest history, it still managed to turn Killer Instinct into one of the Xbox One's best launch titles. Stranger still, the California-based studio was recently acquired by online retail giant Amazon to be folded into its fledgling gaming division. Just what Double Helix will be building now that it's under Amazon's umbrella is unclear, but it appears that Killer Instinct wasn't a fluke — this week the studio launched its last game as an independent company, and once again it’s a terrific reimagining of a classic.
