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.
odst dos not include forge
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.:)
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.
in HALO 3 you are a Spartan and in HALO 3 ODST you are a Orbital Drop Strike Trooper (ODST)
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.
yes it does they anounced it at e3
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
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.
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.
I would say Halo 3 ODST
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
