Mag Rail

"Fires a narrow but extremely powerful energy beam. Alternate firing move delivers an EMP blast that passes through walls."

- Deus Ex: Invisible War description The Mag-Rail is an experimental energy weapon in the final stages of development in Deus Ex: Invisible War. It is first obtainable at Mako Ballistics, after which Omar guards and some enemies (particularly Illuminati Commandos) will begin to use them occasionally later in the game. Its primary fire is simply a semi-automatic energy beam with high damage and accuracy. It's alternate fire is a beam that can shoot through walls, but it does nothing to organic beings and the weapon alone offers no way to see through walls.

Tactics
Although it features high damage per shot, the Mag-rail has a mediocre rate of fire, about the same speed of the Shotgun and Sniper Rifle. It is best used in the hands of someone with good aim and reliable cover, as headshots can be more lethal than an unzoomed Sniper Rifle shot, if the long cooldown time is minded. This weapon is best used with the Increased range and Refire rate Weapon Mods to make up for its shortcomings, though an Increased damage mod can make it even more dangerous at close range, allowing easy one hit kills on most enemies. The Mag Rail is best known for its alternative fire, although using it for such is difficult since it does require the user to be accurate through walls, necessitating Vision Enhancement or some other way to see around corners.
