Hunters

Hunters are aggressive robots that are similar to players in appearance (almost like skeletons.) Upon sighting the player or "alerting" to them the hunter will generally proceed to chase the player until killed, outran, or distracted by drones. When the hunter is about to fire on the player it will project a blue light which will turn red immediately before firing. When engaging in combat with a hunter it is wise to either fight with cover nearby or to simply avoid the conflict all together. Due to the visual feedback of the lights their attacks can be predicted, and given cover the player can avoid the attack or even cancel it if they're quick enough to get out of sight.
