HalfCraft

HalfCraft brings Minecraft into the original Half-Life. You play Gordon Freeman's campaign through Black Mesa as normal, in Half-Life's own maps with its scientists, guards and enemies, but with Minecraft's hearts, hunger bar, hotbar and inventory on top, and Steve's hand in place of Gordon's.

What you get

• Mine Black Mesa's walls and floors for Minecraft blocks: stone, dirt, logs, coal, iron, gold, even the odd diamond
• Collect what you mine into your hotbar and Minecraft inventory
• Craft with Minecraft's own crafting grid and recipes, right inside Half-Life
• Build: place your blocks onto Black Mesa's floors and walls
• Minecraft-style health and hunger
• Each Half-Life map keeps its own block world, so what you build is still there when you come back

How to play

1. You need Half-Life on Steam and Minecraft: Java Edition.
2. Press Play. Half-Life opens in a window, with Minecraft running alongside it to supply the blocks, inventory and crafting.
3. Choose New Game in Half-Life's menu.

Controls: move, jump and crouch with Half-Life's usual keys. Hold left-click to mine, right-click to place the block in your hand, mouse wheel and number keys for the hotbar, I for the inventory and crafting, E to use doors and buttons. Stone and ores need a pickaxe; dirt and wood come out by hand. To place a block, aim at a spot a couple of blocks ahead: like in Minecraft, you can't place one where you're standing.
