The final "word" in overkill. Fires a round that, if hit in the head, leaves you as nothing but a headless, chestless stump of a human being. Excellent for anything.

The Barrett M82A1 is a magazine-fed, semi-automatic advanced marksman rifle. Capable of engaging individual targets and equipment at distances of over a kilometer, the M82A1 is equipped with a 10-power scope, 10-round magazine and bipod. When you really need to reach out and touch someone - or something - nothing beats the M82A1. The M82A1 packs quite a punch. Its recoil means that you must reacquire the target after each shot. Because it is semi-automatic with a large round, it is prone to jamming. This is definitely a very long-range weapon. When it fires it gives off a puff of smoke, making it easier for the enemy to locate you, especially during daylight operations.

Shackteâu

A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
