i highly doubt it. the odst aren't strong enough to weild such a weapon.
It is not in halo combat evolved proper, but you can probably get mods with a gravity hammer in it for halo custom edition. It is in halo 2 used by Tartarus but you cannot wield it. In halo 3 you can wield it i multiplayer and campaign. I have no idea about halo odst but it was not in the list of weapons not in odst so I imagine it is in there.
yes
No in fact they are not. Halo Reach takes place about 4-5 months prior to the events in ODST. At which point the SMG was created and people at UNSC started equipping ODST units with them. The only thing that is remotely close is the fuel rod gun, gravity hammer, pistol (minus the silencer), and assault rifle.
You won't be able to download/get any Halo: ODST demo's, the game is coming out in a few days.
No Halo 4 will not be coming out with a new story line but their is Halo ODST and Halo Reach and If you Buy Halo ODST you will be able to try halo Reach which comes out in 2010.
No. Halo ODST is a special variant of Halo Wars that contains 5 new unit types that will help you beat the game faster. Additionally, ODST is able to play online via Xbox Live with Halo Wars, so you can trounce people online using the new ODST units.
in HALO 3 you are a Spartan and in HALO 3 ODST you are a Orbital Drop Strike Trooper (ODST)
Same way as in halo 3, with an over-charged plasma pistol only due to not being able to use equipment in ODST.
Halo 3 ODST will be released on September 22
Yes you can get the mongoose on Halo ODST
I am not sure. I don't work for binge but I do know that halo 3 odst takes place in Halo 2 and they were going going to name It halo 4 odst but they named halo 3 odst
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
