About Underspace
Underspace is an open‑world sandbox RPG that blends space exploration with Lovecraftian horror. Players can choose any role—from miner to pirate—while navigating handcrafted star systems that are constantly threatened by hyperspatial storms. The game offers a single‑player campaign of sixteen main missions and a wealth of side content, with an early‑access roadmap that includes online multiplayer.
With over one hundred star systems, hundreds of stations, and a deep ship‑customisation system, the title encourages both solo and cooperative play. Players can engage with dozens of factions, tackle more than thirty‑five unique bosses, and modify their vessels using a massive pool of equipment, all while contending with unpredictable weather and eldritch threats.

Campaign and Missions
The core experience consists of sixteen main campaign missions and sixty sidequests, providing a structured narrative alongside optional challenges. Completion of the main quest takes roughly twelve to fifteen hours, while a completionist may spend around three hundred hours exploring all content.
Sidequests and boss encounters add variety, with thirty‑six bosses to defeat and over forty factions offering unique storylines. The missions are set across 114 star systems, each handcrafted and accessible without fast travel.
- Try some sidequests early to learn about different factions before tackling tougher bosses.
- Balance main‑mission progress with exploration to avoid missing hidden story fragments.

Star Systems and Travel
Underspace features 114 handcrafted star systems, each vulnerable to hyperspatial tempests that can alter hazards and loot. Travel is open‑world, with lane lines offering accelerated movement but no fast‑travel shortcuts.
Storms can appear in any system, creating dynamic challenges and opportunities for treasure hunting. Players must navigate these conditions while seeking stations, outposts, and hidden locations.
- Use lane lines for quicker transit when moving between distant stations.
- Monitor storm activity to plan safer routes or to exploit emergent loot.
