Sniper rifle (DXIW)

Sniper rifle is a weapon seen in Deus Ex: Invisible War. It fires a high-powered round that can kill most targets with one headshot. Sniper rifles are used by SSC, WTO and the Knights Templar.

Its alt-fire activates the scope and increases the amount of damage the bullet does.

Tactics
Unlike the original sniper rifle, this one is extremely powerful and useful right out of the box, mostly because there is no skill system. With headshots, it can kill any humanoid target in one to two shots, and can down an Illuminati Commando or Armored Templar with two to three. Make sure to relocate after firing about two to three shots, so that enemies don't find you. Its only flaw is that most of the maps in DX:IW are very small, making it difficult to comfortable use the rifle.

With a silencer and the increased damage mods, the sniper rifle is the most effective weapon in the game. Headshots will kill everything in one hit, and nobody will be able to hear your shots. The only downside is the large amount of ammo is consumes per shot, but this can be remedied by scavenging as many ammo clips as you can.
