What are the differences between the three editions of Halo 3?

[Where's The Brain]

There is a regular edition, a Limited edition, and a Legendary edition. What are the differences between them?

 

[ES.Sharp]

Regular is just the game.

Limited comes with the usual documentaries about behind the scenes, and stuff.

Legendary comes with everything the limited has AND the legendary Master Chief spartan helmet!!!
