Mod Request: Ultrakill weapons

[RitterKnight]

Now I know that the Ultrakill weapons are insane. Trying to shoot a coin and make a ricochet hit an enemy's head is probably hell to code, along with the bouncing projectiles of the railcannon, or the red variant of the pistol. Piercing damage might be difficult too, I wouldn't know. I'd just like to see it be done, and if I can manage the same level of visceral fun that I get from Ultrakill.
