Accurate and deadly anti-material [sic] rifle. Effective against armor, shields, and biotic barriers. Upgrades the Viper Sniper Rifle.
Weighing in at 39 kilograms, the Widow Anti-Material Rifle is primarily used by sniper teams in assault missions against armored vehicles or krogan. While kinetic barriers offer effective protection on vehicles, the kind generated by conventional military field generators are far too weak against the Widow.
The Widow was never designed to be carried and fired by a human. Although this modified model can be carried, no ordinary human could fire it without shattering an arm.
- The Widow is acquired as one of three possible weapons on the Collector Ship mission for Soldiers and Infiltrators. This allows Shepard to use the weapon.
- Conversing with Legion about upgrades will make the weapon available for research. Only Legion can use this Widow.
Note: This weapon is exclusive to either Infiltrator/Soldier Shepard or Legion. No other character(s) may choose to use it.
Legion is the only squad member who can use the M-98 Widow. Legion deals 43% less damage than Shepard.
- The Widow is capable of one-shot kills at any range. Doing this requires a clean headshot with as many damage modifiers as possible, such as:
- Assassination Cloak
- Armor-Piercing Ammo
- Warp Ammo
- Shredder Ammo
- Heightened Adrenaline Rush and/or Commando
- Scram Pulsar series
- Combat Scanner
- Tungsten Sabot Jacket
- Kuwashii Visor.
- Note that the one-shot, one kill policy will only apply to lower ranked enemies and will vary depending on the difficulty level.
- The Widow functionally replaces the Mantis sniper rifle, as it deals more damage and has a higher spare ammo capacity; however, some players may prefer the Viper sniper rifle since it has a larger magazine, despite doing lower damage.
- The M-98 Widow is already very powerful when you first acquire it. When fully upgraded, it becomes a seriously devastating weapon, capable of inflicting significant damage to almost any type of enemy personnel with a single shot, making it an ideal choice for emergency situations and boss/mini-boss fights. It is worth noting that every single major boss, including the final one, has armor as their main defense which makes the Widow even more deadly against them.
- This weapon also scales extremely well with the difficulty setting of the game. On lower difficulties, most shots with this weapon would be overkill, since the Mantis or Viper rifles can do the same with one or two shots. However, on Hardcore or Insanity mode, this weapon can still fulfill the 'one shot, one kill' policy where others may not, thus making it ideal for situations where breaking cover to fire for more than a few seconds can be fatal.
- The Widow, with all damage and bonus upgrades becomes severely damaging when used with Heightened Adrenaline Rush. With a headshot, the Widow can apply 1600 damage to armor, and around 1200 to shields and health. If used in Heightened Adrenaline Rush with Tungsten Ammo, it can deal 1900 damage to armored foes, which, on any mode except for Hardcore and Insanity, is usually enough to take out most opponents in one hit, with certain exceptions (Heavy Mechs, Praetorians, Scions, sometimes Harbinger). Inferno Ammo also generates similar damage.
- Despite the Widow's impressive one-shot, one-kill potential, it loses a great deal of its killing power punching through a shield or barrier. If you're going up against a multitude of enemies protected by shields and barriers, make sure to prepare accordingly by using Disruptor or Warp Ammo to compensate. Alternatively, you could simply use another weapon or power to remove the shield/barrier in order to ensure a kill shot.
Mass Effect 3
- In both the Mass Effect 2 research project and the Mass Effect 3 in-game description, the rifle is referred to as being of geth origin, yet Legion is the only unit seen wielding it. In addition, during the mission Rannoch: Geth Fighter Squadrons, one of the geth memories from the original geth uprising shows a unit picking up the M-98 Widow; when Shepard remarks that it "looks a lot like the sniper rifle Legion used to carry," Legion replies that it is "an efficient model." It also appears visually distinct from other geth weapons, notably the Javelin, and while its presence during the conflict implies that it may be of quarian design, the exact origins of the rifle are unknown. 
- The rifle is referred to as an "Anti-Material Rifle", which appears to be a misspelling of the term Anti-Materiel Rifle, which is the designation given to large-caliber rifles designed to be used against military equipment (or "matériel"), as opposed to enemy soldiers (or "personnel").
- In Mass Effect 2, a Widow can be seen leaning against a railing on board the derelict Reaper ship, and can be scanned for a sniper rifle damage upgrade.
- In Mass Effect 3, the M-98 Widow is roughly tied with the Javelin (in multiplayer the Javelin has been changed to deal more damage) and the M-300 Claymore as the highest damage-per-shot non-heavy weapon in the game; the relative ranking of the guns depends on effective-ranges, upgrade-modifications, power-evolutions and type of target.
- The Black Widow is an Alliance variant of the M-98 Widow.
- Just below the Model # is the text NCC 1701A, which is the hull registry number for the second USS Enterprise, which was first seen in Star Trek V: The Final Frontier.
