Q: Why is the Steam Key of Prospector safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Prospector to your game library. The account format requires more complicated steps and is more prone to errors during activation.

INFORMATION ABOUT Prospector FOR PC

It's a science fiction resource management game where exploration, construction, and automation combine in an experience that grows in scale as you progress.

What begins as a fight to stay alive gradually evolves into the creation of an advanced space base, built from materials you collect, recycle, or discover, even those of extraterrestrial origin.

As you expand your base and upgrade your facilities, you gain access to blueprints and technologies that allow you to automate processes, making production more efficient and allowing you to focus on exploring further afield.

Each planet offers something different: ancient ruins, strange life forms, completely alien ecosystems. But not everything you encounter will be friendly.

Some creatures view your presence as a threat, and defending your territory becomes part of your daily routine, aided by your trusty robot, O.P.H.E.L.I.A., and a laser arsenal to help you survive.
