|The following is based on Fallout Tactics and is not canon.|
A chain with several shackles meant to be worn around the head. It has a small, cylinder-shaped canister attached to it which can hold a small item (of personal high value).
A locket that was in General Simon Barnaky's possession. It is recovered by the Warrior when he finds Barnaky's lobotomized corpse in Scott City. If kept in inventory until the end of game, the locket will be noticed by Simon Barnaky, who turns out to be alive and is Calculator's supporter. The locket will remind him of his wife, Maria Barnaky, and stops him from attacking the player, thus enabling an extra ending option.
An item named Barnaky's letter serves the same purpose as the General's locket. The only difference is that the dialog it triggers is slightly different.
