Adapted for the fold
- Book · Partly folded
The board game, on a table
Half-folded like a laptop on a table, your fleet is on the lower half and the enemy's waters stand up in front of you, as in the classic board game. Two players can face each other across a table, each with their own board.
- Open · Inner display
A 3D ocean on the whole display
Open flat, the battle fills the display as a 3D ocean built with RealityKit, with enhanced graphics and effects. The camera and layout change as you fold the phone.
About Battlefleet Duo
Battlefleet Duo is a turn-based naval strategy game: place five ships in secret on a 10×10 grid, take turns firing into the enemy’s waters, and follow the clues from your hits and misses to sink their fleet. Each shot flies from the ship that fires it across a living 3D ocean, in daylight, at dusk or under moonlit skies, with storms and lightning, and a Classic mode swaps the ocean for the plastic board from the original box. You can play solo, challenge friends online or face off across the table.
It’s built for the iPhone Duo. Half-fold it like a laptop and your fleet lies on the lower half while the enemy’s waters stand up in front of you; open it flat and the 3D ocean fills the display. It also adapts to any iPhone and iPad, and came out on October 23, 2026.
