yes it is it is just after halo 2
No, It does not. Halo ODST is the story of a squad in New Mombasa before/during the events of Halo 3
in HALO 3 you are a Spartan and in HALO 3 ODST you are a Orbital Drop Strike Trooper (ODST)
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.
I would say Halo 3 ODST
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
no halo 3 odst is basically what happened before halo 3 and of course it will have a campaign like any other game so it will not be live only
Halo 3: ODST is the newest of the two, but not the newest Halo game.
halo 3 odst, unlike halo 3, has no matchmaking, sorry
yes, it is set at the battle of Reach which was where the Pillar of Autumn (the ship in Halo 1) was right before it jumped into slip space and found the original Halo. In short, it is set before Halo 1 hence it is before Halo 3
Yes and no. You do not need Halo 3 to play ODST. And you do not need to have played Halo 3 to play ODST. It is an expansion of the Halo storyline. I happens concurrently. No its not this is not an expansion of the story this is just another part of the story.... so basically whats happening in the game halo 3 is happening at the same time as whats happening in halo 3 odst.... They are just two different battle fields. ODST are not Spartans either they are like elite marines Halo 3 odst is between halo 2 and halo 3.
Halo 3 ODST will be released on September 22
Yes you can get the mongoose on Halo ODST
