HALO 3 help?

[johnsamuel4]

ok ok i admit i don't know anything about halo.so please anyone clear this.how many difficulties are there totally in halo.and i think one halo 3 disc will have only one difficulty like a halo3 disc will have legendary on it.if it is so then what is it about the regular & collector's editions?will they have only one difficulty or will they have all four difficulties?

there four Easy, Normal, Heroic, and last legendary

Go here for all info Halopedia.com and go to the one that say powered by wikia... if you cant find it just type in halopedia

all four difficulties will be in every edition
