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

75% of 3,364 reviews are positive · 65% of 58 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.
