M-97 Viper Sniper Rifle
 In-Game Description
Rapid-fire military sniper rifle. Incredibly accurate and deadly at long range, these weapons are popular amongst infiltrators and assassins. Very effective against armor, somewhat effective against shields and biotic barriers. Upgrades the Mantis sniper rifle.
Rosenkov Materials developed this deadly weapon in response to the rising prevalence of kinetic barriers. While kinetic barriers still offer some protection from this weapon, its sheer power and rapid rate of fire make it capable of quickly killing almost any target, regardless of its defenses.
The M-97 Viper Sniper Rifle is found on Illium during the Thane's recruitment mission. The Sniper is near the elevator that leads to the bridge. If you miss it, you have another opportunity to acquire it. When heading up to the roof, the Viper is lying beside a Comm Terminal. Initially only the Soldier and Infiltrator classes are the able to use the Viper. During the mission to the Collector Cruiser, all other classes are given the opportunity to specialize in using Sniper Rifles.
