How long is Halo 3 campaign?

5-10 hours depending on your level of skill and what mode you choose to go on.

Pretty much, legendary will push the bar to about 10 hours... more enemies etc. so you'll end up fighting a war in one spot for quite awhile vs. normal in which you could run through in about 5 hours.

I'd recommend, if you're playing co-op go on legendary, you'll get the most out of it.

If you play by yourself, do heroic, and that'll last you 8-10..

on normal- 8-12 hoursxxcommixx

What skill level are you playing it on because i have about 7-8 hours into it on legendary and i don't think i am close to the end i just completed the "Road to Vol" i don't know how deep i am into it but i don't think i am at the 1/2 way mark yet.....

it took me about 7 hours on legendary with 2 friends.

i beat it on legendary in bout 7 hours. although i beat it on normal first in bout 4-6 hours.

normal is sooooooooooo easy. you just run out thier and kill everything you see. i did not stop to think once. exept on the 8th level which is really bad! it took me a bit cause i had to kill everything 3 times!

um i think i beat heroic from some where between 7-9 hours...(solo)

if i do legendary probally 10-12 hours(solo)
