The Hellclaw (Patreon)

Here's the first new weapon coming with Episode 2, and the one that goes on the 4th slot (also it won't be the only one).

The design, at least, it's definitely going to be a challenge to make the HUD sprites and all. 

Anyway, it's a Demon weapon, sort of a magic gauntlet held together by stone flakes, chains and hellish energy. It's going to function like some sort of Doom Plasma Rifle, with streams of slower energy projectiles and no reloading required. Alt fire will throw magic magma like balls that entrench into the ground and act as proximity bombs.
