The Engineer destroying projectiles

The Short Circuit is a promotional secondary weapon for the Engineer. It is a futuristic electrical device consisting of two probes and rubber sealing, with two large, thick yellow cables extending from a black base piece, connected to a clamp bolted shut over one of the probes. Two orange and grey shell-like pieces extended out over the base and part of the rubber sealing, appearing to be parts of the Engineer's rubber glove. The weapon replaces the Engineer's right arm.

This weapon fires a burst of electrical energy that deals damage to enemies at the expense of 5 metal and destroys enemy projectiles within a 75 degree radius at the expense of 15 metal. If the player has 15 to 20 metal and fires at a projectile, the remaining metal will be consumed; if the player has less than 15 the projectile will not be destroyed and only 5 metal will be deducted. It also does very minor damage to enemies within the area of effect. The weapon's electrical arcs are capable of hitting multiple projectiles in a single shot, but do not hit cloaked Spies. Although unable to operate underwater or deal critical hits through any means (Except a stunned Merasmus), the Short Circuit does not require reloading and instead draws ammunition directly from the Engineer's metal supply.

Enemies killed by the Short Circuit suffer a distinctive death by vaporization: they turn black, hover in mid-air while performing a specific disintegration animation surrounded by team-colored particles, and then disappear into ashes.

An Engineer wielding the Short Circuit cannot collect metal from Dispensers (including Payload carts) until he switches to a different weapon.

This item was awarded in Genuine quality to players who pre-ordered Deus Ex: Human Revolution before August 26, 2011.

The kill icon for the Short Circuit was contributed by Ani.

  • A short circuit is a malfunction in a circuit that allows a current to travel on an unintended path.
  • The filenames for this weapon's sounds within the VPK files reference Lawrence Barrett, a character from the Deus Ex: Human Revolution title known for his gun-arm.
