Hollow Signal

Hollow Signal drops you into the Rust Choir, corroded caverns where the machines still sing. Rusted scaffolding and girders loom behind glowing orange rock as a lone suited explorer takes the first steps into the deep.

Your main tool is a drill: hold left mouse to bore through soft strata and carve your own path. The opening objective, The Drop, is simple: find a way down. The right mouse button fires the Shardcaster, giving you a second tool to bring into the dark.

Keep an eye on your gauges. A heat bar and an instability meter sit alongside your health pips, and a minimap in the corner traces the tunnels you have opened so far.
