Abyssal Bloom

Deep in a lightless trench, a living reef still glows — its Heart pulses faint and warm at the tunnel's end. Things have noticed. Things are coming.

Grow your reef guardians along the current, hold the line across 20 waves, and keep the Heart beating. Upgrade between waves. Spend wisely — the deep does not.
