A PERSISTENT FORTRESS CAMPAIGN
One castle survives thirteen sieges. Walls, damage, buildings, health and supplies carry forward. Your first battle starts with a bare keep and one cannon.
DEFEND
Click or hold where a ship will be when your shots arrive. White shots are yours; red shells are hostile. A shell strikes the first wall or building in its path. Only a visible KEEP HIT reduces keep health. Shoot shells down, or later build a magician. There is no instant repair during battle.
BUILD BETWEEN BATTLES
Construction is untimed. Choose one of three wall pieces in PLANS; rotate and fit it entirely on empty land. No overlap. Touch: drag the preview, then tap PLACE. Three small patch stones help fill awkward holes. Undo is free before battle; salvage returns some supplies.
EXPAND & UPGRADE
Upgrades must fit inside a closed wall area. Tower at 3, larger keep at 5, magician at 7, captain at 9, workshop at 11. Once unlocked, build more whenever you have room and supplies. Each building adds its benefit; the keep can expand repeatedly. Breaches do not switch buildings off; direct hits can disable them. Repair buildings through PLANS. R / ↻ retries this level from its preparation checkpoint. Your castle saves after victories and construction.
CONSTRUCTION IS UNTIMED
Wall pieces cost 1 supply per stone; single patch stones cost 2. Repairs cost 2 per health. Build more of any unlocked upgrade when space and supplies allow.
HARBOR BASTION
Start again at level 1 with a bare keep. This replaces your saved castle, upgrades, supplies and score.
