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.
