Looking for Halo: Landfall, the live-action short film series?
The Halo 3 achievement gives the player 20 Gamerpoints and is represented by a blue plate with the Roman numeral I on it.
Note: You must complete the whole level through from the start; a halfway rally point will not count.
- The name of this achievement could be a reference to the short film, Halo: Landfall. In Halo: Landfall, Marines are in search for John-117's location when he falls to Earth.
