Liquid-metal raider blobs flow through vault channels; containment towers dam and redirect the silver streams, and electrified grills split them — but spilled mercury pools poison your own towers. Signature: dam the stream, then open a side-channel into the smelting grill.
Chrome liquid mirrors on vault steel, toxic sheen rainbow, heavy machinery, cold cyan security light.
Liquid-metal raiders flow the vault channels toward your core. Build mag-coils to grind the streams down. Drop dams to block a channel and open a side-channel door — the silver reroutes around your dam and pours into the smelting grill for coin. Wall it in completely and the flow spills: mercury pools seep onto the deck and corrode your own towers — skim them fast. Electrified grills split big flows in two and burn droplets away.
