New York - Ludlum Entertainment announced on Wednesday that it has re-acquired the rights to develop and publish video games based on the late author Robert Ludlum's works, including the Bourne and Covert One series. The rights had previously been sold to Vivendi Games (now Activision Blizzard), whose Sierra unit published "The Bourne Conspiracy" for PlayStation 3 and Xbox 360 last month. "The international success of Robert Ludlum's The Bourne Conspiracy coupled with continued, dramatic changes in the gaming industry enable Ludlum Entertainment to develop new partnerships capable of fully exploiting the multi-platform potential of the Ludlum content and storylines," the company said.
