There is no way to.
On halo 3 you can't so I would doubt it
No. In Halo 3, you can only play as Spartans and Elites.
yes, unless you want to play halo 3 mythic which comes with ODST
Unfortunately, There is no Halo 3 demo
No. You can not be "Halo" in the Halo Series. You play Master Chief in Halo: CE - Halo 3. You play as Noble in Halo: Reach.
the same way in halo 3 because when you play halo 3 mythic it says your playing halo 3
i bet they do most of cool boys play halo 3
Bruno Mar's stated , I play Halo 3 EVERYDAY .
You can play halo 3 on any xbox 360.
The only time you can play against an NPC is during campaign, otherwise you have to fight your friends or other people.
On the second disk, the multiplayer disk.
you dont ever play as a scarab in Halo 3...you play as a scarab in Halo wars.
