In an interview with Digital Spy, design director David Vonderhaar would not deny the possibility of more downloadable content for the first-person shooter.
When asked whether Treyarch would stop at three map packs, Vonderhaar said: "I can't talk to anything beyond 'Annihilation', but keep your eyes peeled..."
'Annihilation' features four new multiplayer maps - Hanger 18, Drive-In, Silo, Hazard - and Zombies arena Shangri-La.
Call of Duty: Black Ops map pack 'Annihilation' is available now on Xbox Live. PlayStation Network and PC versions will be available next month.
