Javelin

The Javelin is a sniper rifle in Mass Effect 3.

Description
Called the Javelin by Alliance marines, this geth weapon holds a reservoir of ferrofluid, magnetically drawn into the firing chamber and expelled at lethal speeds. Like a high-pressure water jet, the ferrofluid cuts through nearly anything it hits with so much heat that it resembles a beam of light, causing terrible wounds.

Acquisition

 * Single-player: Opt to rescue Admiral Koris in Rannoch. Will be hard to miss during the path.
 * Multiplayer: Randomly rewarded by purchasing a multiplayer item pack.

Player Notes

 * The Javelin allows you to shoot through thin materials without Armor-Piercing Ammo or the Piercing mod.
 * There is a short charge time for the weapon before it fires, which could compromise moving shots.
 * Although it is slightly weaker than the Widow and has fewer shots per clip than the Black Widow, the Javelin allows limited vision through smoke without the scope mod. The Javelin can detect a target and give it a purple outline while scoped in. It seems to be, that only highlighted targets can be shot through their cover.
 * While zoomed, the Javelin can see cloaked enemies, giving them a purple outline, making it especially useful against Geth Hunters, and even more so in the Rannoch missions where Geth Hunters are plentiful.
