39 Days to Mars is coming to the Switch and Xbox!

Pack your teabags, and hang on to your penny-farthing. 39 Days to Mars is coming to the Nintendo Switch and Xbox One in 2019!

I'm excited to say that development is already under way, and you should be off and sailing to Mars on your favourite platform earlier rather than later in the year.

The console releases will come complete with the expansion content from the PC version, as well as all of the small updates and quality-of-life improvements that have been made along the way. Keep your eyes peeled for further announcements - including the launch dates for each platform closer to the time!

If you're impatient for an adventure, you can also pick up 39 Days to Mars right here on Steam - and to celebrate the news it's going to be on sale from the 3rd to the 10th of December!

Don't forget there's also a discord for you to join and chat with us about the game.

Happy sailing!

Mamma Mia! 39 Days to Mars is now available in Italian

Sì! You can now voyage to your favourite red planet completely in Italian, thanks to the hard work of translator Walter Bernardini. If your steam is in Italian by default, the first time you run the game it will start automatically in your language. If you're already playing in a different language, you can switch in the options menu.

This update also comes with some quality-of-life updates, including changes to how controllers are handled. Patch notes can can be found in the community forum.

Happy exploring!

About This Game

39 Days to Mars is a co-operative (and single-player) steampunk puzzle-adventure game.

Step into the shoes of Sir Albert Wickes and The Right Honourable Clarence Baxter, two 19th century explorers who have chosen to pilot the HMS Fearful on its maiden voyage to Mars.

When the steam engine runs out of coal, the ship's cat shreds the navigation chart, and the tea gets cold, it becomes clear that interstellar transportation isn't a walk in the park. It will take the talents of two players working together on the problems that arise to get to Mars in one piece.


39 Days to Mars is a two player co-operative game.

The HMS Fearful is a masterpiece of unreliable engineering, therefore Albert and Baxter will need all the help they can get. Nothing can be done without the effort of both players, who have important roles to play in the adventure.


For the solo voyager, the ship's computer-controlled cat will keep you company. Without a second pair of hands, Albert will need an extra dose of dexterity to navigate the challenges of Victorian space flight.


The mix of action and thoughtful puzzles make it perfect for playing in short sessions. The entire adventure fits comfortably into an evening, or a long tea break.


Be drawn into the world of Albert and Baxter by the unique illustrated artwork. 39 Days to Mars has a rich sound-scape and a beautiful piano score that is punctuated only by the occasional disaster.

The HMS Fearful is ready to embark for Mars!
