halo 3 legendary campaign achievments?

[srokanator]

i had just beat the last level on legendary. this is the first time i played through the game. i also have to share this game with my bro who likes to just play on easy. i dont know which levels he played but when i beat the last level on legendary all i got was the return achievment and not the whole campaign....
in order to get the last one do i have to replay the levels he played in order to unlock them?

Hi,

Sorry, I am not positive on having to replay the one thats your brother did, but are you aware that you can set him up with his own profile? One way I know of to keep your saved games separate.

Peace=)
