You can knock this whole set out in one run by simply finishing the game in Normal, Heroic, or Legendary difficulty mode. To unlock the EVA Helmet, you will need to complete the Campaign on either Normal, Heroic, or Legendary. The Recon helmet was the subject of the game’s pre-order bonus, with such purchases allowing players to use the Recon helmet with the UA/HUL attachment on day one – this specific helmet variant cannot be unlocked any other way.
The Recon set returns in Halo: Reach, though largely unrelated to its Halo 3 predecessor in visuals. Is the recon helmet available in Halo Reach? To get the Hayabusa Body, unlock 5 Skulls.
To get the full set, you will need to unlock every Skull in the game. Perhaps the most popular Halo 3 Armor variation on Xbox Live, the Hayabusa Armor (or Ninja Armor as many call it) is one of the trickier armors to unlock. To unlock the EOD Shoulders, beat The Ark on Legendary.
