Hunters have just as much health as a standard Drone, but their intelligence and signature weapon make them far more dangerous. They'll stay at a distance, usually behind a piece of cover, and make use of the Torque Bow's accuracy to deadly effect. However, Torque Bows have a slight windup time, during which they produce a telltale glow, before they can fire. You'll want to take cover, unless you have a precision weapon; if you're quick enough, you can kill the Hunter before they loose their bolt. Of all the precision weapons, the Longshot is recommended due to its high damage (which outclasses the Markza) and ability to fire without needing to charge first (something that the EMBAR and Torque Bow must do).
The Hunter is a playable multiplayer character for the Swarm in Gears of War 4, and has three unlockable character skins, excluding its Default skin: Color Blast, Onyx Gold, and Spectre. Its Onyx Gold skin is only available in the Onyx Gold Swarm Pack.
