New Tutorial: two short guided battles teach you the game by playing it, from your first shot to Task Force abilities. Offered on first launch and always available from the setup screen. Built for iPhone Duo. Fold it to a right angle and the upright half becomes a privacy screen: your fleet stays on the flat half facing you, and it is hidden whenever the fold opens or closes too far. No more passing the phone at the table. Quick Battle: one tap from the menu to your first shot against the computer. Campaign Book II and the Weekly Admiral's Challenge: everyone faces the same enemy fleet each week, with one attempt and a Game Center ranking. New fleet finish: Copperwake, riveted copper hulls and brass boilers in steam. Use more than one ability a turn while your energy lasts, with a new energy gauge to track it. A new glass finish across the interface, sunk ships that break in two and burn, shot haptics matched to hit, miss and sink, and a share card for the solved Daily Chart. Leaving a local battle now offers Save and return home. The last shot of every battle now plays out in slow motion before the battle report, with a proper victory or defeat moment. Online: join a friend with a short code instead of a Game Center invitation, choose your Task Force fleet after joining (live and by turns), accept turn-by-turn invitations right in the app, and see where enemy sonar swept your waters. New sound effects: a real gun, hits, splashes and sinkings, a sound of its own for every ability, and a horn at the end of every battle. New in Settings: Confirm shots and Confirm abilities. Mark your target first, then press Fire or Confirm, so a stray tap never costs you a shot. A Recent moves log on every battle screen (iPhone, iPad and iPhone Duo) shows the last few things each side did: which ship you hit, and when the enemy repairs a ship.
