RedOctane was an American electronic entertainment company best known for producing the Guitar Hero series beginning in November 2005. RedOctane became a wholly owned subsidiary of Activision in 2006. In February 2010, Activision closed the RedOctane division.
RedOctane was founded in 1999 by the brothers Kai Huang and Charles Huang. They got their beginnings operating the world's first online video game rental service, called WebGameZone. They soon began to create game accessories such as the Red Octane Ignition dance mat, joysticks, and other accessories to build upon already existent musical games. After soon realizing that their game accessories were tied to the launch dates of the games they were producing for, Red Octane began producing games. Their first original game was In The Groove developed by Roxor Games for the Play Station 2 and Arcade platforms. 
RedOctane is known for its Guitar Hero games, Ignition dance pads, and other video game accessories, including arcade joysticks, drums, and guitars for existing music games. RedOctane teamed with developer Harmonix Music Systems to release Guitar Hero in November 2005 for the PlayStation 2. The game was successful and RedOctane had Jack McCauley design more sophisticated hardware for a sequel, which they released in 2006 for the PlayStation 2 and Xbox 360.  
In May 2006, video game publisher Activision announced plans to acquire RedOctane, completing the deal on June 6, 2006. Activision reportedly paid RedOctane $99.9 million in cash and common stock in the acquisition. Activision acquired McCauleys's consulting company, R0R3 Devices, at the same time.
After the Activision buy-out and a split from Harmonix, who went on to develop competing game Rock Band, RedOctane utilized Activision owned Neversoft, the team responsible for the Tony Hawk skateboarding video game franchise, to take the helm on Guitar Hero III: Legends of Rock, which became available in November 2007.
RedOctane released Guitar Hero World Tour in October 2008.
On February 11, 2010, Activision announced the closure of their RedOctane division.
