Doom II

This mod adds the Doom 2 demons into Minecraft, each demon keeps true to the original Doom 2 game while still keeping true to Minecraft's style. All entities have more health than your average mob and dish out a lot of damage. To deal with these enemies there is the shotgun, super shotgun, and plasma rifle though I would highly recommend playing this with a gun mod like timeless and classic for 1.16.5.

Items and mobs that will be added in future updates: Arch-vile, spectre, BFG9000, rocket launcher, pistol, and chaingun
