Looks like a good price for this game.
Its gone up 37p since I posted it but still a good deal.
* Dropping in as "the rookie," a new member of an elite squad of Orbital Drop Shock Troopers sent into New Mombasa on a classified recon mission, you'll be armed with specialised weaponry and upgraded technology, including silenced weapons and a VISR enhanced vision mode.
* Drop feet first into a new way to play Halo with the cooperative campaign mode, Firefight. Form a squad of your friends over System Link or Xbox LIVE and put your skills to the ultimate test against the invading Covenant war machine for glory, high scores, and achievements.
* Three all-new maps make their debut for Halo 3's traditional, chart-topping multiplayer. Heretic, Longshore, and Citadel drop in alongside the original Halo 3 Multiplayer Maps, all packed in and playable from one standalone disc.
