Before We Leave is a non-violent city-building simulation game that unfolds on multiple planets within your own cosmic realm. Emerging from a prolonged subterranean seclusion, your populace has lost all recollection of the surface world. Your task is to reconstruct civilization by constructing huts, cultivating potatoes, and expanding your rejuvenated society to various continents and eventually other planets.

As you progress, you must manage resources, unearth ancient technologies, and establish a network of colonies across multiple planets to flourish in your solar system. However, be wary of the universe's perils. Ancient guardians, remnants of your ancestors, will present challenges to your cities. The planets bear scars from calamities that drove your predecessors underground, and mishandling these disasters could spell trouble. Keep an eye out for colossal planet-consuming space whales that may threaten your planets.

In this (mostly) non-violent game, there are no weapons or territorial disputes over resources. Unless you fail to handle an incoming space whale, your people are safe. Delve into a tranquil city-building experience at your own pace, within a solar system teeming with rehabilitated planets.
