Yes and No. Halo Anniversary is on two discs. The first is the remade Halo Combat Evolved game from 2001. The second disc is Halo:Reach multiplayer with the new graphically enhanced and revised maps from Halo PC and Halo Combat Evolved. In other words, the second disc is more of an expansion pack of maps for Halo:Reach's multiplayer. Therefore, Blood Gulch will still be known as Hemorrage from Halo:Reach.
Actually this guy is wrong. It has been confirmed that it will all ship on one disc. Bungie did that for Halo 3: ODST but 343 isnt doing that.
