How to get it

Sky Heist →

In the pilot-key variant of Sky Heist, the marked helicopter pilot drops the key for the operation-marked heavy helicopter.

No fixed pickup location is verified.

Get and use the mission key

  • When Sky Heist assigns the pilot-key route, eliminate the marked pilot and take the dropped Helicopter Key.
  • Follow the operation marker to the heavy helicopter and complete its unlock interaction before flying.

Mission scope

  • Sky Heist also has a reported helicopter-hacking variant. Follow the assigned tracker rather than adding a pilot hunt to every run.
  • A reusable stash key, compatibility with unrelated helicopters, rarity, sale value and stack limit are not established.
