Shoot, Reload, Shield

Shoot, Reload, Shield is a recurring mental challenge that first appeared in Nova Scotia.

Rules
In this challenge, each player starts out with a gun, and one bullet in that gun. Each player must make a decision; to shoot, reload, or shield (hence the name). If you shoot, you lose a bullet, if you reload, you gain a bullet, and if you shield, you're immune to bullets shot at you. If you shoot someone who is shielding, nothing happens and you lose that bullet, if two people shoot each other, it cancels out. If you shoot someone who is reloading, you kill them and win the round

History
This challenge was first used in Survivor: Nova Scotia as the Final 12 Immunity challenge, right after the mutiny. Breezy had to take an unannounced absence during the challenge due to personal issues, in which then host Sky took over and hosted the remainder of the challenge, which as usual, Yarmouth won 2-0.

This was later used, also in Survivor: Nova Scotia as a Redemption Island duel. It was the first re-entry point in the game, and was between Owen and Leopard, who was just voted out. Leopard one and re-entered the game as a member of the merged tribe, Rock.

This was used for a third time in Nova Scotia as the third duel after the merge, between Leopard and Gavin, this was Leopard's third time playing SRS this season. Gavin defeated Leopard and sent him to the Jury.
