TensuraOpenUniverses

“Confirmed. Reincarnation complete. Welcome to another world… and to all the others.”

You’re dead. And now you’ve been reincarnated… as a slime, a goblin, an angel, an Ex-Machina, or something far stranger still. Tensura Open Universes is a Minecraft 1.21.1 (NeoForge) modpack built around Tensura: Reincarnated, the adaptation of *When I Reincarnate as a Slime*, enriched by the *No Game No Life* universe and a dozen add-ons. Multiple universes, one world: that’s the promise of Open Universes.

Start from scratch. Devour, name, evolve. Become a Catastrophe.

✨ Why you’ll spend hundreds of hours playing this

🧬 A new life with every playthrough

41 starting races: human, goblin, slime, ogre, elf, dwarf, demon, Flügel, Ex-Machina, mystical fox, angel, insect…

Hundreds of evolution paths: from goblin to Holy Hobgoblin, from ogre to Divine Kijin, from slime to… Slime God.

Over 800 skills: unique, ultimate, magic, and combat arts. Upon reincarnation, a randomly selected unique skill can change the entire course of your game.

⚔️ Enemies worthy of the legend

Face off against the Orc Scourge, Ifrit, Charybdis, Hinata Sakaguchi, Gazel Dwargo, Leon Cromwell…

Challenge Rimuru, Carrion, and Luminous Valentine in their own arenas.

And if you dare: Benimaru, Zegion, Velzard, Veldora… beings with millions of EP.

Bonus: the colossi from Mowzie’s Mobs, adapted to Tensura’s stats.
