As one of the universe's leading scientists, you are highly sought after. You've spent the past two years on Alarria, a small terrestrial planet a few light-years from Earth. There, you've studied the diverse native fauna, and your fieldwork has already yielded impressive results. But your time as a humble researcher is coming to an abrupt end.

An asteroid roughly the size of a small country has appeared on radar and is hurtling toward Alarria—a planet-destroying threat. If not addressed quickly, the planet could be wiped out entirely. Three different plans have been put into motion, each with a minuscule chance of success.

A powerful laser is tracking the asteroid's trajectory and will fire as soon as it comes within range, hoping to reduce the dangerous object to dust. An energy barrier might just be enough to alter the asteroid's course and save Alarria. And in a last-ditch effort to preserve some of the planet's unique species, an evacuation plan has been devised. The nearby moon Fortuna, covered in forests, has been tested and found to be capable of supporting life—and thankfully, lies outside the expected impact zone. All that's left to do is relocate as many species as possible before impact occurs.

Your research is at a standstill, as the planet's greatest minds have gathered to develop the three plans. Time is ticking away, and the asteroid is getting closer. What will you focus on? Which plan has the greatest chance of success? There's not a moment to lose...

How to Save a World is a worker-placement game that focuses on hand-building and resource management. Each turn, you assign workers to crucial tasks or play action cards to support your goals. At the end of each round, the progress of your projects is evaluated, and the asteroid approaches again. Can you make the right decisions to prevent catastrophe in this thrilling sci-fi experience?
