off-line Co-op

Hi

right now im playin gears of war offline co-op, and I enjoy it alot

i wanted to know if there are other games with this characteristic, to beat all the single player game but in co-op (offline)

i have heard that GRAW has this feature but its not the same as the 1 player campaign

any suggestions?

PD. i wasnt an xbox 1 owner, so is it worth gettin halo 2 at this point? ( can u play the single player campaign in offline co-op?)
