HL2Craft

You are Gordon Freeman in Half-Life 2, with Minecraft really in it: dig walls into blocks, place blocks to cross gaps and build cover, and fling blocks with the Gravity Gun. Block ids and looks are read from your own Minecraft install at runtime — nothing from Minecraft is shipped. Solo. First version: one intro yard (dig through, defend the block hut from 3 Combine soldiers, free sandbox). Requires Half-Life 2 + Minecraft: Java Edition (your Microsoft account signs in once to Prism).
