Harvest the Hazard
The hazard is your enemy — and your only fuel.
A glowing fluid floods out of the Emitter in the low basin and spreads downhill, pooling deep. You don't want to wipe it out — you want to farm a controlled flood.
Extractors turn fluid into energy. Deeper fluid = more energy — but deep fluid damages structures over time (watch the health bars). Extractors are the toughest.
Relays extend your network to distant ground — but they're fragile, so keep them dry. Everything must stay connected to the Core.
Blasters burn energy to push fluid back and protect your line.
⬢ Metal is a second resource. Miners pull it from deposits (the steel hexagons) — reach and defend them.
Barriers are walls that cost metal and dam a basin into a deep reservoir — but the pressure they hold back erodes them, and they burst at 0 HP. Keep them repaired.
Repair heals a damaged structure — toggle a repair pump from the toolbar. It spends energy (or metal for barriers) so damage isn't permanent.
Beacon — build it in the deadly basin and keep it powered. It's immune to the fluid. Charge it to 100% to WIN.
Everything takes time to build. A placed structure is a blueprint that only starts constructing once the network reaches it through a finished structure — so a relay line builds one segment at a time. Plan ahead.
You lose if the fluid submerges your Core Base. Keep it off the high ground!

Beacon Charged — You Win!
You charged the Beacon in the heart of the hazard while keeping the flood at bay. Masterful flood management.
Core Submerged — Game Over
The flood overran your Core Base. The hazard waits for no one.
