It is almost physically identical to a sniper rifle, but with a suppressor already attached. The rifle is also a darker color from the standard variant, and its scope has a slight purple hue. It has the highest damage per shot of the .308 weapons in the game. In addition, it has a high DPS, a weight of 5.5 pounds (only slightly heavier than a handful of one-handed guns) and high critical multiplier. Like most unique weapons, it cannot be modified. Due to its low weapon health of 85, it degrades somewhat quickly. The scope of this weapon has a 3.5x magnification.
Christine's CoS silencer rifle can fire a total of about 420 standard rounds, the equivalent of 84 reloads, from full condition before breaking.
Found leaning against the wall in a corner right next to an ammunition box on the top floor of the crumbling building outside the north wall of Little Yangtze. It is hard to see as it blends in with the wall.
Three lobotomites will spawn to the north once the Courier takes the rifle. However, they are all facing away from the Courier at first.
If the player character reads Elijah's notes in the watchtower across the Yangtze Camp, he mentions "thought I saw glint (scope?)" from the other side of the compound where Christine's rifle is found. He suspects this may have been the courier he met earlier, but then discounts this suspicion as this courier would have been more direct. It can be inferred that this was Christine's scope reflecting sunlight.
In terms of regular damage per shot, this is the most powerful weapon in the game to use .308 rounds. However, Paciencia beats it in having the highest critical damage using the .308 round.
It is one of few unique weapons to share the same model and color as its original counterpart, silencer aside.
