Arc Projector

The Arc Projector is a heavy weapon from Mass Effect 2 released on March 9, 2010.

In-Game Description
The Arc Projector ionizes targets with a nonvisible laser to ready them for a high-voltage electrical attack. As the lightning-like bolt hits its first target, a sophisticated auto-targeting system paints succeeding targets with the ionization laser, allowing the electricity to take the path of least resistance and arc between them. An entire enemy strike team can be shocked to death with a few pulls of the trigger.

Acquisition
Cerberus Network DLC.

Player Notes

 * The weapon requires two seconds to charge up before firing and doesn't really have a lot of room for error. However, if it does hit a viable target (an enemy or explosive container) it will "jump" to a nearby target. It is quite devastating against organic and light synthetic targets, protected or not, especially if enemies are clustered together. It also carries with it all the effects of Overload, including the detonation of mechs and pyros and enhancing the explosive power of canisters. It will also put organic enemies in a stun state similiar to Reave.
 * This weapon works well on husk missions, scaling down husk speed and aggression to about 80%-90% of the normal rate.
 * The Arc Projector shines on Hardcore and Insanity, as a single fully-charged, well-placed blast can disable the weak protection on common enemies and possibly stun them, as well as eliminating troublesome pyros. Two fully-charged shots are usually enough to take down the shields on an YMIR Mech on Hardcore and Insanity. Any biotic-dependent class can use the Arc Projector to remove shields or barriers (Warp will do against armor) and follow up with Singularity for crowd control. If your squadmates rely on biotics (like Jack or Samara), the Arc Projector can effectively remove the immunity granted by protection layers and allow for biotics to be fully effective.
