Skulltaker Halo: CE: Iron
Skulltaker Halo: CE: Iron is an achievement in Halo: The Master Chief Collection. It is awarded for finding and walking over the Iron skull in Halo: Combat Evolved Anniversary remastered mode on The Pillar of Autumn. The achievement is worth 5 gamerpoints and can be unlocked on any difficulty.
This skull is located in the very beginning of the level, at the back of the Cryo deck. If facing away from the observation platform (where Sam is killed) it is on the left side of the room, behind a stack of crates that are behind the targeting lights.
