Survive CastleMiner Z's world with Minecraft in it.
Minecraft mobs come in alongside CastleMiner Z's enemies. Zombies, skeletons, creepers, spiders and endermen spawn at night and in caves, wearing Minecraft's real skins from your own Minecraft install. Skeletons shoot arrows, creepers blow holes in your base, spiders climb walls and endermen teleport. Your CMZ guns, knives and grenades work on all of them.
Press T for Minecraft's creative menu. It has 24 Minecraft building blocks (TNT included), every sword, pickaxe, axe and shovel from wood to netherite, a bow and arrows, and spawn eggs for all five mobs.
Press Y for CastleMiner Z's crafting. E still opens your inventory.
Minecraft blocks are built into CMZ's own terrain. TNT lights when you hit it, and crafting tables open crafting.
Solo play. Needs CastleMiner Z on Steam and Minecraft: Java Edition. Nothing from either game is shipped: textures are read from your own copy. Mashup worlds save to their own folder, so your normal CastleMiner Z saves are never touched.
