About

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.

Grimstar brings a refreshing spin to a genre that’s been too quiet lately. The game blends old-school real-time strategy with modern ideas — voiced missions, a personal story arc, and a sense of progression through leveling and unlocks. The hero units that carry over and grow stronger after each mission are a great touch, and the different planets keep the gameplay varied. It’s not without its quirks — the writing isn’t perfect, and graphics options are limited — but for the price, you’re getting something genuinely memorable. If you’re into strategic gameplay with a dark sci-fi edge, Grimstar is absolutely worth your time.
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 resources at the end of a mission contribute to long-term progression, encouraging careful planning and rewarding players who can balance aggression with conservation. This subtle twist adds a layer of strategy that goes beyond simply overwhelming enemies, pushing players to think about optimization in a meaningful way. Progression plays a significant role in maintaining engagement across the campaign. Rather than starting from scratch each time, players unlock new units, structures, and upgrades as they advance, creating a sense of continuity between missions. Hero units further reinforce this idea, as they persist and grow stronger over time, adding a touch of attachment and long-term investment. While these systems are not overly complex, they provide enough forward momentum to keep the experience feeling cohesive and rewarding, especially for those who enjoy incremental growth within a strategy framework. Visually, the game adopts a stylized approach that prioritizes clarity over realism. The environments are colorful and easy to read, which is important in a genre where quick decision-making is key. Units and structures are distinct enough to avoid confusion during large engagements, though the overall presentation remains modest in scope. The art direction contrasts somewhat with the narrative’s darker undertones of exploitation and survival, creating an interesting but not fully explored tonal balance. Audio design supports the atmosphere adequately, with functional effects and music that help sustain immersion without standing out as a defining feature. Despite its strengths, Grimstar does reveal its limitations over time. The variety of units and strategic options is somewhat restricted, which can lead to a sense of repetition, especially during longer play sessions. Players familiar with more expansive RTS titles may find the depth lacking, as the game focuses on accessibility rather than complexity. Additionally, the user interface and control scheme can feel slightly rough around the edges, occasionally making management tasks less intuitive than they should be. These issues do not break the experience, but they do highlight the game’s smaller scale and indie origins. The pacing of the campaign is steady but not particularly dynamic. Missions introduce new elements gradually, but the overall structure remains consistent, which can be both a strength and a weakness. On one hand, it ensures a smooth learning curve; on the other, it limits the sense of escalation that many players expect from strategy campaigns. The story, while intriguing in concept, never fully evolves into a central driving force, instead serving as a backdrop to justify the player’s objectives rather than a compelling narrative in its own right. Ultimately, Grimstar: Crystals are the New Oil! delivers a focused and approachable RTS experience that succeeds in capturing the essence of the genre without overextending its ambitions. It offers a satisfying gameplay loop built around efficiency and progression, supported by a clear visual style and a consistent structure. However, its limited depth, modest presentation, and underdeveloped narrative prevent it from standing out as a truly memorable entry in the strategy space. It is best suited for players looking for a streamlined, single-player RTS that can be enjoyed without a significant time investment, rather than those seeking a deep or highly competitive experience. Rating: 7/10
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.
Not my cup style of game
x-- 7/10 --x Very enjoyable RTS. Simple and satisfying! I also quite enjoyed the story, it's definitely unique enough to hold it's own against other indie titles!
