is halo 3 odst dowloadable content?

it is a different game halo 3 odst stand for Orbital Shock Drop Troops its spouse to be before spartan we played in halo 3 and halo 1 and halo 2 i don't know if they are changing that now or what but that's what i have been told my a inside source

Halo 3 ODST is an entirely different game. It comes out this fall.

Halo Odst is complete diffirent game and is not a downloadable content

No it isnt it comes out fall 2009. But like halo wars if u get limited edition u will get the new map pack earlier for halo 3

it is an entirely different game coming out september first. It will be more tactical oriented than the other halos because you are not in a super suit. comes in a new case and everything.

No it is a new chapter to the game but isnt completely new experience

for instance the only changes i no of is that you dont play as master chief and the smgs now come with silencers

no i think its a whole disc go to ebgames and search

I think so.
