The game is a tactical shooter played from a first-person perspective. As the title suggests, a large portion of the game consists of stealth, staking out targets and firing sniper rifles. Bullet trajectories are subject to wind, gravity and flight time, all of which players must account for when taking shots. To simplify this procedure, easier difficulty settings contain indicators that highlight enemies and show precisely where a bullet will hit.
The main weapons used in the game are silenced pistols, knives and various types of sniper rifles. In missions that are played with characters who are not snipers, the stealth aspect is dropped in favor of faster-paced "run and gun" scenarios. An exception to this are spotting missions, in which the primary objective consists of marking targets for a computer-controlled sniper character.
Most of the game takes place in a dense jungle environment. Waypoint overlays at all times display the correct routes through the areas players must traverse....
