Ever thought the world was just a little too nice to you? Have you ever wished mining was more dangerous and exciting and dangerous? Look no further!

This mod adds a few world generation features that make living more difficult! These features include mines, silverfish veins, lava pockets, and things that shoot arrows everywhere, all using blocks and features included in vanilla Minecraft!

The frequency of features and mobs in mob spawners (as well as nearly everything else) can be adjusted in a super-duper properties file! The properties file is generated in your .minecraft/config directory.
