Well I found all this stuff inside the coding of the Halo 3 Beta a few weeks ago. I originally posted it on H3F but I have recently reformatted and organized it so that it doesn't hurt your eyes so much areax69/H.gif.

Campaign Difficulty Descriptions
Easy - Your foes cower and fall before your unstoppable onslaught, yet final victory will leave you wanting more...
Normal - Hordes of aliens vie to destroy you, but nerves of steel and a quick trigger finger give you a solid chance to prevail...
Heroic - Your enemies are as numerous as they are ferocious; their attacks are devastating. Survival is not guaranteed...
Legendary - You face opponents who have never known defeat, who laugh in alien tongues at your efforts to survive. This is suicide.
