Halo 2 DLC

Can you still buy dlc for Halo 2 Vista? If so, how?

I don’t think so.

Pretty sure it comes with all the maps already, except Desolation and Tombstone which are exclusive to Xbox.

You could download user made maps but I personally prefer Halo Custom Edition for that.

H2 for PC has no DLC and H2 for Xbox has a DLC disk.
