• Achievements unlock the moment you earn them, not when the run is

booked.

• Three land in your first session: the first hull sunk, the first

island lost, and five waves held.

• The middle band rewards understanding: the flagship of a boss wave,

ten barrier segments in a single drag, six upgrade tiers on one

emplacement, all four support powers in one run.

• A few are things to find: a blackjack in your own casino, a bank and

a trading post and a casino side by side, three hulls to one mine, a

burning and snared hull killed on the harpoon.

• And three walls: twenty research nodes, fifteen waves without a

scratch on the island, fifteen waves at Ascension 10.

• Every one is findable from its own description. No hidden conditions,

nothing to look up.
