Battlefleet Duo is a turn-based naval strategy game that brings the familiar board game of hidden fleets, careful deduction, and tactical choices to a living 3D ocean. MADE FOR IPHONE DUO • Tabletop mode: your fleet on the lower screen, the enemy’s waters standing up in front of you. • Full screen mode: takes advantage of the big screen with enhanced 3D graphics and effects. • Two players face to face: each with their own board, just like the classic game. • The game camera and layout adapt as you fold the device. • Bonus Classic mode: switch the ocean for the plastic board from the original box, pegs and all, for a hit of nostalgia. Battlefleet Duo also adapts to any iPhone and iPad. THE BATTLE Watch each shot fly from the ship that fires it. Hits bring fire and smoke, and defeated ships sink beneath the waves. Battle in daylight, at dusk or under moonlit skies, with storms, rain and lightning. Place five ships in secret on a 10×10 grid, then take turns firing into the enemy’s waters. Follow the clues from your hits and misses, uncover their ships, and sink their fleet before they sink yours. Choose Standard rules for the familiar game, or Enhanced rules where each ship brings its own weapon: an air strike hits three squares in a line, a torpedo travels down a column to the first hull, a star shell gathers intelligence, and a missile targets one square every turn. Keep each ship afloat to retain its weapon. PLAY YOUR WAY • Solo: challenge the computer on Easy, Medium, or Legend. • Face to face: on two devices over the local network. • Pass and play: one device between two players, with fleets hidden at every handover. • Online: invite a friend or find an opponent through Game Center. Continue unfinished battles later, whenever you’re ready for your next move. MAKE THE FLEET YOURS Visit the Shipyard for alternative ship designs, paint schemes, shot effects and custom markers on the opponent’s grid. Complete daily and weekly orders, earn sovereigns to spend in the Shipyard, and rise from Cadet to Admiral and beyond. Your progress syncs through iCloud across devices using the same Apple Account.

Your first game is free • Or play far away, a round at a time, through Game Center: a friend you ask, or a foe that finds you • Or work up the ranks alone: the Deckhand, the Shipmate, the Captain and the Commander • The computer only knows what a player in its seat would know • Your fewest shots against each rank are kept SALVO • Fire a shot for every ship you still have afloat, all at once • Lose a ship and you lose a shot, so every sinking counts twice • About fifteen turns each, where one shot a turn takes thirty.

Verdict
