The story
Double Helix Games was formed as the result of a merger between The Collective and Shiny Entertainment, two video game developers owned by Foundation 9 Entertainment. Shiny had been acquired by Foundation 9 in October 2006 under the terms that it would co-locate with the already-owned The Collective. On October 9, 2007, it was announced that both studios had relocated to new 60,000-square-foot (5,600 m2) offices in Irvine, California, and were being merged, which was expected not to result in any job losses. The amalgam, led by Michael Persson, received the name "Double Helix Games" in March 2008.
In July 2009, as part of a round of consolidations within Foundation 9, Double Helix suffered an undisclosed number of staff cuts. On February 5, 2014, Double Helix announced that it had been acquired by retailing company Amazon. The studio was integrated into the Irvine location of the retailer's Amazon Game Studios division, which had been established in 2012. Microsoft Studios, the publisher of Double Helix's Killer Instinct, stated that it would be working with a new development partner to continue development on the game.
