Morse

Morse is a wave-based strategy game in which you use Morse code and artillery to repel the Kaiser's advancing fleet. You enter dots and dashes to navigate a changing grid of letters and numbers, then fire at German ships hidden in the dark. Survive the escalating assaults until dawn.

Learn Morse code

You begin with a handful of letters and can master a telegraphy tree that expands the battlefield. The game includes 40 characters to learn, three telegraph types and calibration settings, as well as Iambic and Sideswiper control schemes. A manual covers the game and how to apply and expand your knowledge of Amateur Radio.

Find and sink ships

Artillery strikes briefly illuminate distant vessels, revealing their positions. A blast close enough reveals a ship permanently; direct hits deal maximum damage and save ammunition. Consistent precision also speeds up the shell feed, helping you breach even the strongest ships.

Upgrade your defenses

After each successfully repelled assault, choose one of two upgrade cards using either a dot or a dash. Upgrades stack and can unlock new artillery shells, improve reconnaissance or strengthen your sea mines. Mines can be placed in different formations to reveal and destroy ships that get past the artillery; upgraded mines can withstand damage, use timed detonators and relay warnings of breaches.

Waves and game modes

Each wave brings a newly chosen isogram, an extended vertical row, more units and powerful German vessels. You can also play a frantic campaign featuring a midnight breach of the Blockade of Germany, or use skirmish mode to practise telegraphy with a range of different words. Expert Mode tests your knowledge and skill, while a growing collection of modifiers lets you vary the gameplay.
