Halo 3 Legendary :)

if me and some other people got on co-op campaign and skipped to last map, starting from beginning and we beat it, do i get the legendary achievement? (i really don't wanna play through campaign again )

and if it does work, anyone wanna help me

 

I think u have to finish every level to get the achievement

 

You have to complete every lvl on lengendaruy unfortunately .

I suck at Halo, I can't even beat the 2nd lvl on legendary xD, but I'm aiight online lol.

 

but if i play it in co-op, i get achievement?

 

Yes, both players will get the achievements if all lvls are done on legendary, single player or co-op, it doesn't matter.

 

good, i can beat it in legendary, but i suppose with 3 friends and playing with the scoring system maybe playing through campaign won't be to bad
