Getting Started in CastleMiner Z
Surviving your first few days in CastleMiner Z requires quick resource gathering and a solid defense strategy. The game drops you into a hostile world where enemies spawn constantly. You need to gather materials, craft weapons, and build a safehouse before night falls.
Gathering Early Resources
Your very first priority is collecting wood. Trees only grow on the surface in the Foothills biome near spawn, so grab it while you can. Chop down the nearest trees and gather at least 20 blocks of wood. This gives you enough material to craft basic tools and a starting weapon.
Wood is not completely gone once you leave the surface. Skeletons in deep caves and the Hell biome drop wood on death, giving you a renewable supply later in the game.
Once you have enough wood, open your crafting menu and make a basic pickaxe. Use this to mine straight down into the earth. The surface level is dangerous at night. Mining down keeps you safe from the initial wave of surface enemies and lets you gather essential ores.
Look for coal and iron as you mine downward. You need these materials to move past the early game. Coal powers your furnaces and iron is the foundation for your first real weapons and tools.
Always keep your essential gear in your hotbar. Items in your hotbar stay with you if you die, while your main inventory drops on the ground.
Upgrading Your Tools
Basic wooden and stone tools break quickly. Your goal is to craft an iron pickaxe as fast as possible.
- Mine iron ore and coal.
- Build a furnace to smelt the iron ore into ingots.
- Craft the iron pickaxe at your crafting station.
An iron pickaxe is required to mine higher tier materials like gold and diamond. You cannot progress to the late game without it. Do not waste your iron pickaxe on dirt or stone if you have lower tier tools available. Save its durability for valuable ores.
The Copper Trap
Copper is the first ore you find, but do not craft Copper tools. Copper pickaxes and weapons degrade so fast that you spend more time replacing them than actually progressing. Skip Copper tools entirely and push straight to Iron. Save all your Copper for crafting ammunition instead. Bullets are the best use of Copper in the game.
Building a Safehouse
Nighttime brings aggressive zombies and dangerous flying enemies. Staying out in the open is a quick way to lose your inventory. You need a safehouse to survive the night.
Your building material choices depend on your difficulty setting. On Easy and Normal, dragons cannot destroy standard blocks like sand, stone, or wood. A basic stone or sand shelter keeps you safe. On Hard mode, dragon fireballs obliterate sand, dirt, wood, leaves, and standard rock on impact. If you play on Hard, you need to dig underground for protection until you can craft blast-proof walls.
On Hard mode, only five block types survive dragon fire: Bloodstone, Diamond, Space Rock, Space Goo, and Bedrock. Plan your base materials around this if you play on the highest difficulty.
As you progress, upgrade your base with Diamond or Bloodstone walls. These materials resist all standard dragon attacks. One exception exists: the Undead Dragon can shatter even Bloodstone, so Space Rock or Diamond walls are the safest long-term bet. Make sure your base has a roof and a secure entrance. Enemies swarm any opening they find.
Basic Defense Strategy
Craft a shotgun or an assault rifle as soon as you have the materials. Melee combat is risky and drains your health quickly. A shotgun easily handles early game zombies at close range.
If you see a dragon early in the game, run and hide. You do not have the firepower to kill a dragon with basic iron weapons. The ammunition cost alone makes the fight a waste of resources. Get underground or behind blast-proof walls and wait for the dragon to leave the area.
Inventory Tips
The game does not explain its inventory controls well. Right-click on any item stack to split it in half. Keep right-clicking before you place the items down to drop them one at a time. This is critical for sharing ammunition and resources with teammates in co-op.
Items in your hotbar stay with you when you die. Your main inventory drops on the ground. Always keep your best weapon, your pickaxe, and a stack of ammunition in your hotbar slots.
