Crypt Dephts

This mod from the authors of the TRfree antivirus, adds new blocks and tools to Minecraft, a new dimension and a new portal and two new liquids, two new biomes and please, don't miss the entrance to the portal!

The trfree team isn't yet sure what future features will be added, but one thing is certain: new blocks, tools, and perhaps even armor and other structures will be added, along with new biomes. The current features are the less functional ones: every time you enter the world, you're given a petrol bucket and a kill oil bucket. For now, there's a new rare structure (the only one created so far), new blocks, two new biomes, enchantments for the pickaxe and sword, and tools (sword, pickaxe, and shield).

These features influence the user experience by making them curious to explore and search for new blocks, biomes, tools, etc. that are not normally present in Minecraft.
