How do I find a co-op match in Halo 3?

[jsmack79]

I can't find a co-op match for Halo 3. Where do I go? Campaign? Matchmaking?

Do I need to know someone to play or will it just find people for me to play co-op with?

I can find VS games just find... where's co-op???


Thanks.

if u mean campaign co-op, all u gotta do is go to campaign and have someone join ur party then just start, there isn't any co-op thing like that in halo 2
