Follow the objectives
wait for the next halo
You complete the game
in HALO 3 you are a Spartan and in HALO 3 ODST you are a Orbital Drop Strike Trooper (ODST)
Unlock Halo 3:ODST's Campaign Complete Achievement. Once you beat the ODST campaign, visit Halo Waypoint on the dashboard to unlock the item.
you have to beat ODST on legendary alone or with another ODST.
I would say Halo 3 ODST
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
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 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
