About the game

What you do in a play session

In 2217, Earth faces severe climate challenges, and the need for new resources is more urgent than ever to sustain technologically advanced megacities. The Moon, with its rich mineral reserves, emerges as the solution. Ten years after a successful first campaign, the 20 largest nations on Earth invest in the 'Future Two' freight rocket for a second mineral transport mission. In '21Moon: Second Campaign', you take on the role of an opportunistic investor, aiming to accumulate the greatest fortune possible before the rocket returns to Earth. During eight months of in-game time, your goal is to invest in and operate mining corporations on the Moon. These corporations establish bases and build transportation networks between valuable mineral deposits and crucial facilities, mining as many resources as possible. Your final wealth will be the sum of your personal money and the market value of the shares you own in one or more of the seven available corporations. This game is an updated and enhanced variant of the original '21Moon' from 2020, bringing new twists and rule adjustments for an even more immersive experience in the universe of '18xx' games with a space theme.
