I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Are you ready to make world exploration exciting again? This mod changes world generation by adding many unique buildings on the ground and dangerous dungeons underground. Every structure looks great and is full of hidden traps, valuable loot, and dangerous enemies.

New locations:

The Ice Camp: An abandoned camp in the endless snow. Watch your step: under the tents, there are deep basements with many traps and ice skeletons guarding the treasure.
The Forest House: An old, ruined house deep in the woods that looks empty. But do not let its look fool you - there is a secret underground bunker hidden inside!
The Savannah Dungeon: A huge network of underground mazes right under the hot earth. Get ready to fight hordes of zombies, survive hard challenges, and find very precious loot!

Start your journey, uncover the secrets of the past, and prove that you are the ultimate explorer!
