True Carnage Add-on 1.21+

Dive into a world of chaos and danger with the mod True Carnage, which introduces over 100 unique hostile mobs into Minecraft. From tiny creatures to giant monsters, each of them will hunt you down, forcing you to choose: fight or flee.

Besides the mobs themselves, the creator has also added many new items and blocks. Most of them do not yet have a functional purpose, but we hope they will soon.
