Firefight will have 2 people on the same box.
I highly doubt Halo: ODST will not include the Halo 3 achievements. Although, how would we unlock Ghost Patrol and such? Hmmm.....
yes it will. you can get every halo 3 multiplayer achievement in halo odst's second disk.
you will have to play the original halo 3 to get the campaign achievements.
halo odst achievements = 1000 gs (campaign/firefight)
halo 3 multiplayer = 750 gs (multiplayer, new legendary/mythic achievements, also mythic 2)
halo 3 campaign = 1000 gs (campaign, vidmaster annual, skulls etc.)
so the 750 gs from multiplayer is "shared by the games. (i am assuming they will only show up in halo 3's achievement list, after all it's halo 3's multiplayer)
