No.
The Halo Odst Disk 2 comes with all maps (Plus 3 extra), and the ordinary halo 3 disk comes with no added map packs, so you don't have another 12 maps.
It depends on what halo your talking about Halo CE: 2001 Halo 2: 2004 Halo 3: 2007 3 years in between each game
halo 3 obviously
Halo 3: ODST is the newest of the two, but not the newest Halo game.
The halo time line goes Halo Wars, Halo: Reach, Halo:CE (halo 1), Halo 2, Halo: ODST, Halo 3. Halo 3 and ODST are practically at the same time.
Yes! if he wants it and it'll be about as violent as halo 3, (which isn't violent anyway) and it'll be fine for a 12 year old
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
After Halo 3 there was halo wars, halo 3 ODST, and Halo reach. A new company (not Bungie) will be making a Halo 4 and rumor has it there will be a remake of Halo Combat Evolved.
it goes halo, halo 2, halo 3, halo 3 odst and soon halo reach will be available

the same way in halo 3 because when you play halo 3 mythic it says your playing halo 3
