Human Hunters main focus is the atmospheric immersion. As the Hunter your goal is to have a "thrill of the hunt" moment. You should feel this moment of excitement eliminating them and having control over your victims. 
While as the Runner you'll feel scared and helpless. Your only way out is to play the game the rich elites have put you in.

Human Hunter has 2 main roles,
Hunter & Runner

Hunter:
As a Hunter your goal is to eliminate all runners before sunrise.

Utilize multiple mechanics to track them down.
Building things like Motion Sensors, Cameras, Tripwires, Fires etc.
Using your bow to either keep your distance and stalk your prey or just purely run straight after them.

Motion Sensor will automatically detect motion and highlight the areas as well as beep giving their location away.

The camera can be toggled for thermal and non thermal, place and view across map for information.

Place trip wires high to clothesline them stunning the runner for longer, or lower to trip them but have it hidden better.

Runner:
As a Runner your goal is to survive until sunrise.

Be careful as you're not only surviving from the Hunter you're also fighting the cold.
Collect resources around the map to craft different mechanisms to delay the hunter or throw them off.
Use campfires to help prevent the cold or as a decoy to distract the Hunter.

As long as you can survive until sunrise you'll win
