About CastleMiner Z
CastleMiner Z is an online co-op survival horror game set in a block-based, ever-changing world. You explore, gather raw materials, build structures and craft weapons and tools to defend yourself from dragons, zombies, skeletons and other monsters. You can play alone or online with friends.
Explore and build
The world is infinite, with deep places to explore and enemies to fight. In Endurance Mode, you travel across dry deserts, snowy mountains and icy expanses toward the ultimate guardians of the abyss. Each game generates a randomized world, and your party’s death is permanent.
Game modes
- Endurance Mode: Run, fight and sneak across the world while facing zombies, dragons, skeletons and other enemies.
- Survival Mode: Build permanent structures and defenses while surviving in the world.
- Creative Mode: Build with simplified crafting and adjust or eliminate the enemy threat.
- Dragon Survival Mode: Face wave after wave of the game’s biggest dragons.
Worlds can be saved in every mode except Endurance. You can build with enemies turned off, then load the same world with friends and turn them on.
