Activision has finally released Call of Duty: Black Ops today, sparking a fierce price war as the big retailers vie to sell as many copies as possible.

If you don't have those games to trade in, Blockbuster is charging £44.99 for Black Ops on its own.

Supermarket chain ASDA is running a close second in the price war and is reducing Black Ops from £36.99 to £4.97 when Fallout: New Vegas, Fable 3 or Star Wars: The Force Unleashed 2 are traded in.

HMV is selling Black Ops for £7.99 when customers trade in Medal of Honor, or for £42.99 otherwise.

Specialist retailers Game and GameStation are discounting Black Ops on PS3 and Xbox 360 to £24.99 when any other chart titles are purchased at the same time, or when Halo: Reach, Dead Rising 2, F1 2010 or FIFA 11 are traded in.

Internet retailers are offering simpler deals; Play.com is currently selling the PC version of Call of Duty: Black Ops for £34.99, while Steam is selling digital copies for £39.99.
