AWM-S

The Accuracy International Arctic Warfare Magnum or AWM, known in-game as the AWM-S (the "S" presumably standing for "suppressed" or "subsonic"), is a sniper rifle that was released in update 0.5.0. It is arguably the rarest weapon in the game, even beating the M249.

Info
The rifle uses the .300 Subsonic ammunition type, and is the only weapon in the game to do so. It does 200 damage per shot, and 300 damage for headshots. It is believed that the only way to get the AWM-S is from an Golden air drop crate. It has many similarities with the SV-98 with the slow fire rate, both being snipers, and the high damage. It is one of only three bolt action snipers in the game, the other two being the Mosin-Nagant and the SV-98.

This weapon was presumed to be rarer than the M249 by Corrupt X, and may be because it is probably only obtained from golden airdrops.

Trivia

 * The ID for the weapon is called the "awc".
