Hunter is a 3D action-adventure game in which the player navigates around a series of islands. The player controls a soldier in a large three-dimensional world where he can move freely by walking, swimming or using various vehicles such as cars, vans, tanks, ships, bicycles, helicopters, hovercrafts or even rowboats and surfboards. Each vehicle type has its unique properties. The game world also features a large variety of buildings, most of which can be entered and explored. Other in-game characters include enemy soldiers, civilians and animals such as seagulls, sharks and cows. The player also has a wide range of weapons ranging from a regular pistol to SAM-missiles, grenades, land mines and timed explosives. Surrounding terrain can be surveyed with aerial observation units and radar. Food and money can be used to bribe and gather information from other characters. Target coordinates can be recorded into a log book, and the player can see his position in the game world on an overlaying map.
Hunter features a rather sophisticated AI for its time. In addition to shooting, enemy soldiers can also drive vehicles and track the player down. Guard towers, tracer guns, cannons and SAM launchers have the ability to shoot towards the player, and homing missiles launched by the enemy accurately follow the player's vehicles.
