Tactical analysis
The threat pulse is a part of the preset Ambusher loadout, and it is unlocked through player progression at level 6 for use with custom loadouts.

The threat pulse reveals the location of opponents within a fixed radius around the player. Compared to the similar threat sensor item, the threat pulse is a purely portable item which has an effect that is always centered on the player's current location and has a larger area of effect.
