No
Yes, there will be Forge mode in Halo 3: ODST... but on the other hand there is two discs so there might not be in the halo ODST disc.:)
odst dos not include forge
You cannot make your own maps in Halo: ODST, it doesn't contain forge world. Halo 3, Halo: Reach and Halo 4 all contain forge world.
Forge.
No. ODST doesn't have multiplayer, excluding firefight (which can't be forged, and not even for matchmaking) and co-op campaign. But ODST does come with a Halo 3 multiplayer disc, which includes all of the original multiplayer maps and the DLC maps. That disc also includes forge mode.
No - because there isn't a Halo 3 ODST multiplayer mode (there is a separate disk that contains all of Halo 3 multiplayer maps) but as for the actual game, the only multiplayer mode is firefight. In firefight you fight against AI (Covenant) enemies with your friends, so there isn't forge.
Yes, Master chief is still in space with cortana in halo 3 odst he counts as a spartan and in multiplayer forge or any you and or friends are Spartans and when i played campaign i found a dead spartan on a building roof with a brute.
Halo 3 ODST will contain a brand new and exiting campaign, ready to be completed. It will also have all the maps in Halo 3 and all the DLC including the 2nd half of the Mythic Map pack. Halo 3 ODST (like other Halo games) will have secret skulls on the new maps so you can get achievements on Forge and on the Campaign. Also it is NOT Halo ODST it's Halo 3 ODST.unfortunantely it will not have killstreaks like mw2 which i do believe is a much better game since odst is only considered an expansion packand yes mw2 is not better than odst.
forge probably not but it will come with 3 new maps for halo 3 and you play fire fight and the campaign in a bigger version of nomindbasa from halo 2
in HALO 3 you are a Spartan and in HALO 3 ODST you are a Orbital Drop Strike Trooper (ODST)
Halo 3 ODST will be released on September 22
Yes you can get the mongoose on Halo ODST
