Lethal Company, with Minecraft's blocks, ores, items, sounds and music read from your own copy of Minecraft: Java Edition.
What you get
Minecraft Pickaxe in the ship terminal's store (buy pickaxe, 35 credits). It swings like the shovel and hits monsters just as hard.
Minecraft ore veins on every moon: stone, coal, iron, redstone, gold, diamond and emerald ore. They sit against the facility walls (as deepslate inside) and in mounds outside, and crack with Minecraft's own break stages as you mine.
Ore loot is scrap: coal, raw iron, redstone dust, raw gold, diamonds and emeralds sell for quota.
Cobblestone building: mined stone gives you cobblestone. Press E with the pickaxe to place a block where you look, to wall off a door (monsters walk around blocks) or build stairs out of trouble. You land with 4 blocks.
Minecraft music while you're out on a moon, and cave sounds inside the facility.
Co-op for up to 4 players through Lethal Company's own lobbies. Mining, drops and blocks are shared, and Melty's join link puts friends straight into your game.
Needs: Lethal Company and Minecraft: Java Edition (1.17 or newer, launched at least once). Nothing from either game is included: every player uses their own copies.
