Bring Minecraft items into R.E.P.O. — spawn them as grabbable physics loot from your own install.
R.E.P.O. Mine
A mashup of R.E.P.O. (Unity) and Minecraft: Java Edition. You play inside R.E.P.O.; Minecraft is the companion game whose blocks and items are read from your own Minecraft install at runtime - nothing is copied out of either game.
Open the Minecraft-style inventory overlay (keybind E) showing a 9-slot hotbar and 27-slot inventory grid with real Minecraft item textures loaded from your .minecraft/assets folder. Click any item to spawn it into the R.E.P.O. world as a textured physics cube, then grab and carry it with R.E.P.O.'s own physics and sell it at extraction.
Games you need: R.E.P.O. (Steam) as the host, plus your own Minecraft: Java Edition copy. Solo play.
