The Hellshot.

The hellshot is a weapon in the Doom 2016 reboot which is exclusive to multiplayer game play. It is an advanced energy weapon that uses Argent energy to fire red-coloured, plasma-like bolts. Hellshot is a semi-automatic weapon of moderate accuracy and firepower. Its alternate firemode launches incendiary shots that can set targets ablaze and inflict burning damage over time. Due to being an Argent-fed weapon (like the BFG), the Hellshot is presumably an in-house UAC weapon development product.
