Overview[edit]

Halo 3[edit]

The Key
H3 Achievement The Key.png
40 Gamerscore icon taken from Xbox.com. Originally a single block colour (with the two circles both being white and the 'G' a transparent cutout), but modified by myself to display nicely on dark *and* light themes, and to be reminiscent of the pre-Xbox One gamerscore icon.

In the original game, it is worth 40 Gamerscore and is unlocked by beating Cortana from the start of the mission on Normal, Heroic, or Legendary. In the original game it is represented by a blue plate with the Roman numeral VIII on it.

Halo: The Master Chief Collection[edit]

In The Master Chief Collection it is only worth 10 Gamerscore, though it can also be unlocked on any difficulty. The achievement's Xbox art is the loadscreen image for the level.
