Operational history

By December 2559, Spartan Hudson Griffin had a threat sensor installed as part of his GEN3 armor.^[3] On May 28, 2560, John-117 found Griffin's removed armor in the Tower and took his threat sensor for himself. While facing off against Chak 'Lok in order to rescue the imprisoned and tortured Griffin, the Weapon suggested that the Master Chief use his new threat sensor to combat the Sangheili's active camouflage.^[3]

In-game information

Halo Infinite

”

The threat sensor is a usable piece of equipment in Halo Infinite. Players can shoot the device to any surface, including onto enemies themselves. The device then pulses periodically and highlights enemies in red on the HUD. Enemies are highlighted even when they are obscured by solid barriers or cloaked.^[1] The threat sensor is especially useful in combating enemies that make extensive use of their active camouflage in battle, such as Special Operation Sangheili, Sangheili Ultra, Warlods as well as bosses like Chak 'Lok and Jega 'Rdomnai.^[8]

Upgrades

In campaign, the threat sensor is acquired from the body of Spartan Makovich in the level The Tower; then it can be upgraded by collecting and spending Spartan cores. In multiplayer, the fully-upgraded threat sensor can be selected as "Threat Sensor (Campaign)" under Sandbox settings; however, in multiplayer, the fully-upgraded threat sensor does not have "Operative" and "Omniscience" upgrades. In Forge, the fully-upgraded threat sensor can spawn at an equipment pad by enabling the Legendary variant option.
