Most map packs are 800 Gamerpoints and need to be purchased via XBOX LIVE. Sometimes, there are discs out there for sale, but I highly doubt there are any for Halo 3. There used to be for Halo 2 though. Bottom line: Purchase from XBOX LIVE for 800 Gamerpoints. (Except Cold Storage, that one is free!!!!)

It is not like the multiplayer map pack. Halo 3 Recon is a new game that depicts a new campaign as an elite ODST unit during the events of both Halo 2 and 3.
