39 Days to Mars

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. 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 39 Days to Mars perfect for playing in short sessions. The entire adventure fits comfortably into an evening, or a long tea break. The HMS Fearful is ready to embark for Mars!
