Astromine is a co-op survival game where you and up to three friends land on destructible voxel planets to scavenge resources, build bases, and fend off alien threats. Developed by Alientrap, it blends base-building, resource management, and combat in a procedurally generated solar system. Land on alien worlds, strip-mine materials, craft tools, and construct ships to progress. The game emphasizes teamwork, as solo play can be grueling without help. Released in 2026 for PC, it’s a pick-up-and-play simulator with a focus on survival and exploration. Think of it as a cross between Minecraft and a space-based Rust, but with chunky voxel environments and co-op at its heart.
You start each session by selecting a planet, then drilling through terrain to collect minerals, organic matter, and alien tech. The voxel world breaks apart cleanly as you dig, revealing layers of resources. Combat involves shooting flocks of aggressive alien creatures with ranged or melee tools while managing health and oxygen. Base-building requires balancing structural integrity and defense; walls can be reinforced or rigged with turrets. Multiplayer sessions demand coordination: one player might mine while another builds, and a third handles combat. Missions include escaping hostile planets or assembling ships for space travel. Controls are responsive but can feel clunky during intense fights, and the learning curve steepens as later planets introduce tougher enemies and scarcer resources.
Astromine has a 82% positive rating on Steam, with 35 hours of average playtime and a 62% completion rate. Community moods are split: 70% call it "fun," 55% say it’s "challenging," and 30% find it "frustrating," often due to resource scarcity or combat mechanics. Playtime spikes at 40-50 hours for full planet conquests. Achievement data shows 300+ total trophies, with players averaging 75% completion. One review praised the "crisp voxel visuals and satisfying base-building," while another griped about "repetitive early-game loops." The co-op mode is a highlight, with 90% of players rating it as "essential to the experience."
Astromine works best as a co-op session with friends who like survival and crafting. The price is unknown, but 300+ achievements and 50+ hours of content justify it for dedicated groups. Solo play is possible but punishing, and late-game pacing slows without clear goals. If you’re into voxel worlds, base-building, and teamwork, this is a solid pick. Skip it if you hate grinding for resources or struggle with coordination. The game isn’t perfect but offers enough depth to keep returning for another planet.
