About this game
The earth’s resources are depleted, and the energy crisis is imminent. But there is still hope – the discovery of a distant world, which is rich in a new kind of natural energy resource. The name of the new world is “Grimstar”. That is where your brother lost his life, and the laws of the company he worked for require you to take his place until his contract is fulfilled. So you set out to do your service and to discover more about your brother's death.... Grimstar is a real-time strategy game about exploiting a foreign planet as efficiently as possible.
Single-player campaign: Exciting single-player campaign: which also revolves around finding out more about the death of your brother.
Level up system: With every mission you play, you level up and unlock valuable upgrades and new units and buildings with which you can exploit the planet even more efficiently.
Different Planets: There are 3 different planets to choose from, each of which is unlocked upon reaching a higher level. Each planet has its own vegetation and special characteristics. The missions on each planet have different victory conditions: Either all crystals must be mined or alien artifacts must be collected. In addition, there are various command missions in between, during which special objectives must be fulfilled.
Hero units: There are various hero units in the game, which once called can be called anew in every mission without giving up resources. The hero units also level up and thus become stronger after each mission. And as soon as they level up enough, they get new weapons.
Explore and exploit: Explore the alien planets and harvest all the resources to make your company a success. Command your armies against the alien hordes of the enemy planet as effectively as possible and using as few resources as possible. The more resources you have left at the end, the higher your level.

Update 1.10.0
Update 1.10.0Back from the summer break – and of course with a fresh update! From now on, enemy factions have a brand-new defense building: it blocks the orbital Plasma Cannon within a certain radius. Translation: wiping out an entire base with a single shot from space? That’s history. Now you’ll need to take down these structures first – adding way more tactics, tension, and depth to the game.Read full article on Community Announcements (Sven.Rahn)Patch NotesOfficial
