dont you think they should just throw in the halo 3 campaign on odst disc 2...they already have forge, custome games, and thearter with all 24 maps on the disc they should just copy and paste halo 3 campaign onto disc 2 so we have the whole halo 3 game..cause if not then we are going to have to put our original halo 3 disc in just for campaign..so we will have to switch 3 differant discs....so shouldnt they just add halo 3 campaign on disc 2.
