Games Like Sea of Tranquility

In the near future, government and private agencies launch manned moon missions.

You are an astronaut on a routine rotation at an underground base. As you prepare to relieve your colleague, nothing goes as planned. The Moon is not ready for us.

The journey spans serene moon plains to intense, action-packed tight spots—from cold corridors to vast open-world landscapes.

As you piece together your escape, explore optional paths and discover the Moon isn’t as abandoned as it seems. Your trusty rover will carry you across the wastelands until it’s time to go on foot and explore exciting locations - from crashed vessels to abandoned research facilities - at your own pace.

On your journey, many courses of action are required. Solving puzzles until you need to dodge a war missile, trawling through cramped corridors until you have full freedom to explore the vast peaceful surroundings - but dangerous things remain forgotten beneath the tranquil planes.

On your journey, you will travel vast distances, land shuttles, help new acquaintances, navigate through caverns with a radar device, hack cameras, propel yourself across a valley and mess with explosives. You will gain many devices but the most important tool you have are your wits to get you off the rock!

Sea of Tranquility is a first-person sci-fi adventure that combines open world exploration, puzzles and action.
