legendary achievement? In Halo 3, I've completed 6/9 missions on legendary but 3/9 on Normal. It was strange how I did most of the missions on legendary but got the normal achievement. I really want the Legendary and Heroic achievements but I dont want to do the all of the last 3 missions on legendary to get the achievement. Can I simply beat the last mission on Legendary to get the achievement? If you can, please explain everything. Thanks.

You have to beat the whole game on legendary, you can look up each level and see which ones you have accomplished with highest difficulty. I can help you tomorrow, add my gamertag - Uplift

The reason you got the normal achievement is because you will get achievements for the highest completed set. so imagine when you beat legendary its like a wild card that matches normal and heroic
