Campaign Complete: Legendary (Halo 3 achievement)

Can I get this achievement on co-op as well as on single player if i want to.? Spartan 107 05:20, 10 December 2007 (UTC)

yes, you can. I finished some levels that were too hard and boring to me with my friends. I sat back in the corner and watched the whole time and got credit for beating the mission. -- Blemo ^TALK • _{CONTRIBUTIONS} • _{SERVICE RECORD} • _MESSAGE 05:45, 10 December 2007 (UTC)
