About The Promethium Effect

The Promethium Effect puts you in charge of an aggressive asteroid-mining corporation competing to acquire Promethium, a rare element that can revolutionize manufacturing speed and productivity. More Promethium means greater profits, but rival corporations also want the resource—and what you own.

You manage the corporation while taking on the roles of pirate and bounty hunter. Protect your assets, steal from weaker rivals, post bounties and pay others to do your dirty work. The game combines fast-paced asteroid shooting with clicker-style gameplay.
