Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Aug 7 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About


The Kaisers Fleet approaches! It falls to you to learn the secret language of Morse Code and repel the naval onslaught through timing, tactics and telegraphy.
MORSE is a wave based strategy game elegantly operated with just two controls, Morse and Artillery:
Enter dots and dashes to navigate an ever changing grid of letters and numbers.
Unleash an arsenal of artillery to reveal hidden enemy positions with the flash of your strike and swiftly sink them with precision and speed.
Between waves, upgrade your reconnaissance and firepower and bolster your blockade of sea mines crucial to holding the line. With each wave the waters change, new letters are learnt, shells are spent, ships scuttled and defences tested. Can you prevail?
Navigate ever changing grid of letters and numbers using the lost language of Morse Code. Learn a handful of simple letters then master the telegraphy tree to fully scale the battlefield. Master different telegraph control schemes such as Iambic and Sideswiper.
German ships are shrouded by the cover of darkness, illuminate their positions using the flash of your artillery strikes. Distant vessels will briefly brighten, land a blast close enough and warships will be permanently revealed.
Rain down salvos of shells on the Kaiser's fleet with your artillery. Deliver direct hits for maximum damage and to save ammunition, consistent precision is rewarded with a faster feed of shells that can breach the hulls of even the strongest ships.
After successfully repelling each assault, pick between a pair of upgrade cards to bolster your arsenal, chosen with either a dot or a dash. Unlock new deadly types of artillery shell, improve your sea mines or enhance your reconnaissance. Upgrades stack so choose wisely!
Deploy a blockade of sea mines to reveal and destroy any ships that slip past your artillery. Mines can be bunched and scattered in various formations. Upgraded mines can withstand damage, have timed detonators and can relay warnings of breaches.
With each wave, a new isogram is chosen, the vertical row extends, the number of units increase and new powerful German vessels emerge from the dark waters. Survive until dawn.


Whilst an enjoyable experience with mouse, keyboard or Steamdeck, the authentic way of playing MORSE is with a telegraph key. Here are some of the different types of "homebrew" hardware that players have fashioned to play the game with. Visit the Steam Discussions for the project to learn about how to build your own, including the newly announced Teaspoon Telegraph.


A frantic campaign mode featuring a midnight breach of the Blockade of Germany.
A skirmish mode to hone your telegraphy skills on a breadth of different words.
40 different characters to learn in Morse Code.
3 different telegraph types and calibration settings to tune to your needs.
Put your knowledge and skill to the test with Expert Mode.
Mix up gameplay with a growing collection of modifiers.
Connect up a homebrew or commercial telegraph key for the authentic MORSE experience.
Explore the manual to learn more about MORSE but also how to apply and expand your knowledge of Amateur Radio.

OST挺棒的 不知道能否上spotify?
Faktycznie można się wyrobić w nadawaniu i słuchaniu. Jeszcze lepsza zabawa jak się zrobi jakiś telegraf, nawet prowizorycznie.
I like the concept and the game. I am sure it'll be my filler-quickie kinda game

게임하면서 영문 모스 배우기 좋아요. Vband용 usb PC에 꽂으면 실제 CW용 키도 쓸 수 있구요. 개발사에서 모스 활용한 다른 게임도 더 만들었으면 좋겠네요.
Definitely recommend didn't even mean to but 4 and some change hours later I know morse code.

I think this game is better for practicing sending Morse code than learning to listen to it. Emmm,maybe adding the inner auto‑key feature support would be nicer for people who aren’t HAMs.
Quite literally the ONLY reason i would have ever found out the ham radio community existed. Anyways, 200 dollars later and i have now joined the good ol lads sending long and short radiowaves over long distances. Back to the game, its surprisingly simple for a rougelite. The adittional cards you recieve each round certaintly help, and are in fact neccicary, but its not like there are any crazy builds. The real progression is how fast you can send morse, how good your memory is, and how well you can prioritize what groups of ships to target. i REALLY wish the screen was bigger, and the ui was smaller, but thats really the only complaint i have so far. In anycase, good game & .... .- ...- / .- / --. --- --- -.. / --- -. .
super interesting for CW training or mosre training. I bought it at 88 HKD, if it's 50 will be more selling. Thanks for the Dev team!
