Hunter 3D is a realistic first-person hunting sports shooter. The player learns how to target, shoot and hunt with different rifles via an avatar represented by arms and hands holding a gun.
The game divides areas with tabs at the bottom of the home screen. At the Store, the player uses coins they earn in matches to buy boosters that help them with sight zoom and wind resistance. At the Training Camp, they learn how to shoot better across 140 levels. They can't unlock some areas of the game without first performing well in a specific number of these matches. In the AI Battle zone, they compete in tournament matches at a shooting range against the game's AI. Lastly, in the Hunting area, they kill virtual deer across seven levels.
Hunter 3D also provides an Arsenal area where the player can upgrade to more powerful rifles (power + 3%, 8% or 14%), red-dot scopes with zoom ranging between 90% and 120%, and options for better wind resistance. The game rewards them with coins and medals. They can win gold, silver and bronze medals for various achievements.
