Grimstar

In this bleak future, Earth’s energy crisis drives a megacorporation to mine the alien world of Grimstar. When your brother dies mid-mission, company law forces you to take over his contract. What begins as mandatory labor soon spirals into a deeper mystery and a battle for more than survival.

The single-player campaign unfolds through a series of escalating missions, each expanding your control and revealing more of Grimstar’s hidden secrets. You’ll manage resources, construct outposts, and command units in real-time battles across hostile terrain. The game’s progression system encourages ruthless efficiency, rewarding players who meet corporate goals with stronger units, advanced buildings, and access to more dangerous worlds.

Grimstar spans three unique planets, each with distinct environments and challenges. Whether harvesting alien crystals, retrieving artifacts, or following morally questionable directives, players are expected to produce results at all costs.

Hero units provide added strategic depth. These powerful characters level up across missions and gain new abilities without costing in-game resources, making them key assets as missions grow more complex.

With its sharp focus on strategic gameplay and a narrative rooted in corporate dystopia, Grimstar invites players to think critically about the cost of progress, even when it’s the only way forward. Check out the official launch trailer below.
