What is Ostranauts?
A single-player space survival RPG and simulation sandbox set in a solar system isolated from a ruined Earth. As an indebted scavenger seeking independence, you strip derelict ships, repair or sell parts, build and fly a customized craft under Newtonian physics, and manage a crew’s physical and emotional needs.
For you if...
- +you enjoy slow, difficult salvage and survival sandboxes
- +you want detailed shipbuilding and Newtonian spaceflight
- +you like managing crews, systems, and basic survival needs
Not for you if...
- −you dislike steep learning curves and limited guidance
- −you want fast-paced action instead of methodical salvaging
- −you prefer simple ship controls and forgiving survival systems
What players say
77% of 3,272 reviews are positive · 66% of 145 in the last 30 days
Players praise the methodical salvage loop, detailed ship construction, freeform progression, and hard-science-fiction setting. Common complaints focus on an awkward interface, poor documentation and quality-of-life support, plus bugs that can disrupt quests or saves; many recent players say the released game still feels unfinished.
