The Mag Rail is an energy weapon in Deus Ex: Invisible War.


The Mag Rail is an experimental energy weapon produced and supervised by Dr. Patton, the Mag Rail Project Manager for Mako Ballistics. It was launched in 2072 just after Alex Denton comes in the Seattle Mako Ballistics Facility.


Its primary fire is a semi-automatic high density energy beam with high damage and accuracy, not affected by damage resistance and can easily severely damage bots or a power-armored person. Its alternate fire is an EMP blast through walls and other solid objects, striking the target without damaging the intervening objects, which also affects organic beings and disabling bots and turrets in only one shot. Both firing modes uses a medium amount of damage per shot.

No matter what firing mode is used, there is a noticeable cooldown between shots.


  • 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. Cover is useful to avoid damage between shots, as the cooldown time leaves the player vulnerable to attacks without any way to retaliate.

The Mag Rail is also very useful against enemies who are resistant to bullets, such as bots or Templar Paladins,. and the secondary fire deals EMP damage and disables bots and turrets in one shot nd does a good amount of damage to the RB-76 Military bot and Templars equipped with Templar V68A power armor with only a few shots.

  • A level 3 Vision Enhancement aug makes it possible to to see everything in a level, which works very well with the alternate fire's ability to pierce through walls. With Vision Enhancement and the Mag Rail, the player can defeat foes in a room without ever having to enter it.
  • A Refire rate mod is a good mod for the Mag Rail because of the cooldown between shots. With the mod, the cooldown period can be decreased to the point where the gun will be a bit more effective than before.
  • Equipping the Ammo scavenger mod is also useful, as the weapon consumes a good amount of ammo per shot, no matter what firing mode is used.
  • Those using the Mag Rail to snipe through walls will find the Increased Damage as useful, as it'll defeat enemies faster, making it less likely they'll find the player when the player alerts them after the player starts shooting.
  • The Mag Rail is difficult to use in close-quarters combat, so a sidearm built for close-quarters, such as the Shotgun or the Energy blade, can be very useful.



  • Synergyzes well with the Vision Enhancement augmentation in Level 2 and Level 3, allowing the player to see organic enemies through walls in Level 2, and electronic devices or bots, items and interactive objects additionally in Level 3.
  • This weapon is even better when coupled 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 weapon exists in some form in many first person shooter games, namely Goldeneye: Rogue Agent, where a walkthrough pointed out that it is in so many games because it is so fun to use.
  • Its ability to shoot through walls, makes it a likely technological successor to the laser rifle.
