About Grimstar: Crystals are the New Oil!
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.

If you’re after a quick single-player RTS fix, this one’s a great pick. The visuals are clean and colorful without being overly busy, and the gameplay is easy to pick up, perfect for newcomers but with enough challenge to keep things interesting. Controls are smooth, the story gives just enough context without dragging things down, and the persistent hero units add a nice sense of progression. For the price, it’s a real gem. Definitely worth a look if you enjoy strategy with a sci-fi twist.2 found this helpful

Grimstar: Crystals are the New Oil!, developed by SvenRahn Games and published by indie.io, presents itself as a compact real-time strategy experience that blends classic RTS sensibilities with a light layer of modern progression systems. The premise revolves around a future where Earth’s traditional energy sources have collapsed, forcing corporations to seek alternatives on distant planets. Players step into the role of a contractor tasked with extracting valuable crystal resources from hostile alien environments, driven not only by profit but also by a personal connection tied to a lost family member. This narrative framing gives the game a slightly more grounded emotional hook than many strategy titles, even if it remains largely in the background. The core gameplay loop is rooted in familiar RTS mechanics such as base construction, resource management, and tactical combat. Players gather crystals, expand their infrastructure, and build military forces to defend against or eliminate alien threats. What sets Grimstar apart is its emphasis on efficiency. Missions are not just about survival or victory, but about maximizing resource extraction while minimizing waste. Any remaining…1 found this helpful
This is actually a fun little RTS game, reminds me a lot of C&C, just you call troops in like reinforcements rather than building. army size does seem limiting at first, though it does get bigger and you never need them lol, some missions are stupidly easy, one i just finished had me move all over a decent sized map, 88 troop supply, briefing that u have to collect all on the map and will have to go through nests.. yea 3 little baby nests that don't fight back, im guessing the enemy was supposed to build up and fight.. if not.. then that mission is far to easy for mid game. that said though, i do enjoy the game so far, its well worth the small cost.1 found this helpful
Not my cup style of game
