UNDERTALE, a classic game from years ago with a lasting fanbase still kicking years later. Minecraft, a great game from many people's childhood and a great survival game that is fun for playing with friends or even just alone.
So what happens when you mix these two?

(Huge update may be coming soon for out of Beta release.)

 Welcome to - UNDERTALE: BLOCKY SOULS!

 

An UNDERTALE mod that mixes these two games, allowing the players to live in a Minecraft world with UNDERTALE aspects, abilities, souls, items, and more!

 

In this mod you can use a specific item that helps you gain the ability to use your human soul! Whatever soul you get, depends on your luck I suppose. Learning what your soul is won't be easy though, you must find or craft a special item to discover your soul and be able to use the abilities of it. Unless of course... You aren't human.

 

Unfortunately, playing in the world of UNDERTALE has its downsides. Upon obtaining a soul, you are liable to die. No, not like you normally would. You die, fully, no respawning. You become a spirit and spectate. Even if you cheat, you can't come back unless you find a way to remove your abilities before returning.
The only soul that can ignore no return, is DETERMINATION.
