How co-op works
Two local players control Albert and Baxter through one voyage, with both required for the ship’s unreliable machinery and physics puzzles. They operate complementary controls, position components together, repair failures, and coordinate navigation tasks that cannot be completed with one pair of hands.
About this game
Set aboard a rickety 19th-century spacecraft, 39 Days to Mars is a true co-op puzzler that requires two players to communicate and coordinate their way through a whimsical voyage. Each player controls one half of the expedition, and most challenges demand both crew members work together at the same time. Solo adventurers can enlist the ship's cat as a companion, though the game truly shines with a human partner.

The journey unfolds as a series of illustrated vignettes where players must repair broken machinery, navigate hazards, and solve environmental puzzles using shared information. Success hinges on clear communication, since both players often hold pieces of the solution or must operate complementary controls simultaneously. The hand-drawn steampunk setting and gentle humor keep the mood light even when pipes burst or compasses spin.
Designed for local couch co-op on a single screen, 39 Days to Mars supports Steam Remote Play Together for online sessions. The compact campaign encourages replay with a friend, turning each playthrough into a collaborative problem-solving session that rewards teamwork over quick reflexes.

Frequently Asked Questions
Can I play 39 Days to Mars solo, or do I need a second player?
You can play solo with the ship's cat as your AI-controlled companion, but the game is designed for two players and works best with a human partner. Most puzzles require both crew members to coordinate simultaneously, so having another person to communicate with makes the experience much smoother and more enjoyable.
Does this support online co-op, or is it local only?
It's primarily a local couch co-op game played on a single screen, but it does support Steam Remote Play Together, which lets you play online with a friend as if they were sitting next to you.
What kind of co-op gameplay should we expect?
39 Days to Mars is heavily communication-focused. You'll solve puzzles together where each player controls different parts of the ship or holds different pieces of information. Most challenges require both players to work at the same time-repairing machinery, navigating hazards, and operating complementary controls-so expect to talk through problems rather than rely on reflexes.
