Bohemia has announced a pre-E3 content update for the ArmA III alpha test which adds two new sniper rifles to the players' arsenal. The "Sniper Package" includes the Gepard GM6 Lynx and the M320R Long Range Rifle.
The former weapon is "a semi-automatic anti-materiel rifle using 12.7x108 mm ammo. Its purpose is to stop or disable targets such as light armored vehicles, armored rifle troops, light shelters and helicopters from 600–800 m range." The latter "is a .408 caliber sniper rifle, valued for its accuracy up to 2000 meters."
Guns aren't the only inclusion into the Sniper Package. The update also adds ghillie suits for camouflage, sniper optics and a rangefinder.
The update will be downloaded automatically in the 0.60 Steam update. For additional patch notes, check.
