>>50757134You know when you play Minecraft and you dig one very long tunnel hoping for something, and then you see diamonds in a wall? It's like that, only you can't detect the diamonds unless you're running, and you automatically get stopped by the buried item.
So in practice you just run through hallways and around room borders and whenever you stop for seemingly no reason, there's a buried item near you. In RTDX the xray specs show you them though.
