It is best known for developing three games in the Crash Bandicoot franchise, and the Prototype series of games.

On 28 June 2012, due to the financial failure of Prototype 2, Radical Entertainment suffered a "significant reduction" in staff, and would from then on focus solely on supporting other Activision studios, while ceasing development on their own projects. Studio head Dr. David "Dave" Fracchia left the company in May 2014. Radical Entertainment most recently contributed to Destiny in 2014.
