Halo 3 Legendary?

Can you get the legendary achievment buy just doing the last mission or do you have to go all the way through? Can you do it in co-op and get it also?

you've gotta do them all and yes you can do them via co-op, try it on four players, you'll find it as if the mode was set on easy

Yeaa ive already tried to just start the campain on legendary at just the rally point on the last level, but sorry to say it keeps track of alll your levels so u have to complete every single one in order to complete in on legendary. and yes coop counts for your achievement.
