Lightning Gun

The Lightning Gun is an energy firearm that disperses a constant stream of electricity to the target.

Multiplayer
The Lightning Gun can be unlocked in the multiplayer at level 14. The player spawns with 150 ammo (250 is the max ammo). The weapon features two fire modes:
 * Primary Fire - Short range energy weapon that fires a constant stream of electricity. The lightning does approximately 8 damage.
 * Weapon Mod - Creates an electrified field upon hitting a surface that can damage multiple targets. The lightning does approximately 5 damage.

Trivia

 * The appearance of the Lightning gun in Doom (2016) is a possible allusion to the Thunderbolt from Quake (And extension, Q3's Lightning Gun), and how Quake II and Quake 3 Arena had the BFG10k.
 * The Lightning Gun was originally considered for Singleplayer (due to the mesh lacking the MP_ tag used for MP only weapons) and was called the "Arc Wielder"
