Can you get Vidmaster challenge Brainpan without Halo 3?

Can you get this achievement with just Halo 3 ODST or do you need Halo 3

 

[Christopher]

When you purchase Halo 3:ODST, it comes with 2 Disc. Disc 1 contains ODST, Disc 2 contains the Halo 3 Multiplayer, which has ALL the maps already on it. So to answer your question, No. If you have ODST you should have the Halo 3 Multiplayer disc so you can get it on that.

Back of the box (for Collectors Edition but Regular Edition has both disc as well.)

Well, the achievment IS for halo 3, and it's for Recon armor IN Halo 3... so the answer is yes, you need Halo 3, not ODST.
