Marksman 3D

Marksman 3D is a first-person 3D sniper shooter built for the browser. You look down a realistic scope at a 3D range — move the mouse (or drag a finger) to swing the crosshair, then click or tap to fire. The twist is real ballistics: every round drops under gravity and is pushed sideways by the wind, so a long shot lands well below and beside where you aimed. You must hold the crosshair high and into the wind to connect.

Hold right-mouse (or the SCOPE button) to zoom in for distance work, and hold SPACE / HOLD BREATH to steady the natural scope sway — but your breath meter is limited, so time the shot. Press R or RELOAD to refill the magazine. Each mission gives limited ammo and a mix of stationary, patrolling and peeking targets; clear every hostile to advance. Headshots score the most, chained kills build a combo multiplier, and a kill triggers a short slow-mo kill-cam. Five missions ramp from a calm range to a timed contract, ending in a Victory screen.

One rule to respect: blue civilians marked with a white “!” are off-limits. Hitting one costs 150 points and breaks your combo, so pick your shots. Your best total score is saved on the device.

The ballistics are real, and worth doing the arithmetic on. Rounds leave at 520 metres per second under 9.8 m/s² of gravity, out to a maximum range of 280 metres. At 200 metres the flight takes about 0.38 seconds, so the bullet drops roughly 0.7 metres — meaning you hold nearly a full metre above a chest-height target at that distance. Zooming narrows the field of view from 58 degrees to 15, which is what makes that hold-over readable at all.
