What happens when a mega-corporation sends you to finish the mission that killed your brother? You pick up the contract, strap in, and survive long enough to ask why. Grimstar, the upcoming real-time strategy game from Sven Rahn Games, officially drops on June 16, 2025, on Steam—and it’s not your typical resource-gathering grind.
Set in a bleak future where Earth’s natural resources are nearly gone, Grimstar puts you in the boots of a reluctant company worker forced to continue a high-risk mission on an alien world teeming with crystalline energy. What starts as another day at the office quickly spirals into something darker. The planet is hostile. The locals are violent. And the truth behind your brother’s death isn’t buried as deep as the minerals you’re mining.
Strategy With Purpose
At its core, Grimstar is a classic single-player RTS with a modern, narrative-driven twist. Across a multi-mission campaign, players will:
-
Harvest resources from an alien landscape
-
Build and expand infrastructure under constant threat
-
Command military units to secure extraction zones
-
Survive and adapt as enemies evolve and resistance escalates
Each mission emphasizes smart resource management and tactical decision-making. Waste too much, and progression slows. Conserve wisely, and you’ll unlock advanced units, new structures, and game-changing tech.
Three Planets. One War.
As the campaign unfolds, players gain access to three distinct alien worlds, each with its own biome, terrain, and tactical layers. From wide-open mining fields to claustrophobic cave networks, no two missions play the same. Objectives range from full-scale extraction to stealth-based artifact recovery and precision strike operations that demand tight control and sharp planning.
Hero Units That Matter
One of Grimstar’s standout features is its persistent hero units. These elite characters can be deployed in every mission without draining your resources. They level up independently, unlocking unique weapons and new abilities that make them essential tools in your tactical arsenal—whether you’re punching through enemy lines or pulling off high-value assassinations.
Not Just a War for Resources
Beneath the surface-level conflict lies a story of systemic exploitation—of you, the workers around you, and the planet itself. Grimstar isn’t just about victory conditions; it’s about questioning who benefits, and who pays the price. The company isn’t asking you to win—they’re demanding it. And in the end, you’ll have to decide what that cost really is.
Grimstar launches June 16 on Steam. Whether you’re in it for the strategy, the story, or the challenge of surviving a corporate war on an alien world, this one’s worth watching.
