To elaborate:
Halo 3 ODST comes with two discs. First disc is ODST, and has Campaign, Firefight, and Theater (all of which are private; that is, no matchmaking). Disc two is Halo 3 Mythic, and comes with everything Halo 3 has excluding Campaign. It also has all add-on Map Packs to date. However, Firefight has the same concept as Custom Games; no EXP.
Hope that cleared things up.
