Is Ostranauts worth it for you?

We tell you who should skip it, too.

Play it if you…

Good fit
  • Players interested in spacecraft customization who want to install salvaged parts and manage ship systems
  • RPG players who want character backgrounds, relationships, and decisions to affect later interactions
  • Space-simulation players who want manual piloting alongside fuel, air, food, crew, and debt management

Skip it if you…

Saves you a refund
  • Players seeking a simple flight model may hit a wall when learning Newtonian movement, controls, switches, and docking.
  • Players looking for a low-maintenance space adventure may find the combined demands of worn parts, supplies, crew needs, and debt too demanding.
  • Players who want a narrowly directed story may not enjoy choosing whether to pursue or avoid contacts, recruit crew, and shape later conversation options.

Our take on Ostranauts

The bounce point arrives in the cockpit: flight requires manual control, Newtonian movement, switch operation, and careful docking. Players expecting arcade-style steering may hit the wall before the salvage and crew systems have time to matter.

What is Ostranauts?

Survive on the fringes of a solar system isolated from a devastated Earth by scavenging derelict ships for usable components.

Refurbish what you find, sell it, or spend the proceeds on fuel, oxygen, food, and debt payments. Shape a character through their history, earnings, credentials, abilities, and personality, with those choices affecting social encounters and ship operations. Assemble a vessel from practical modules, link its systems, supply energy and fuel, and replace damaged hardware. Piloting uses Newtonian motion, so operating consoles, toggles, and docking procedures require care.

Crew members have bodily and psychological needs, and their histories guide their decisions. Dialogue, alliances, hiring, and future possibilities can change according to previous actions. Modders can alter much of the game through editable plain-text data files.

How Ostranauts plays

01Ship salvage economy
Recovered parts can be installed on the vessel or sold to fund supplies and debt payments.
02Custom ship systems
Thrusters, hull mass, subsystems, power, fuel, and worn components affect the vessel’s operation and flight.
03Newtonian flight
Piloting involves manipulating controls and switches while managing movement during docking and travel.
04Crew relationships
Characters have physical, emotional, and social needs that influence their choices and interactions.
05Character backgrounds
Creation choices establish income, qualifications, traits, skills, and starting connections.
06Plain-text modding
Much of the game data can be edited through plain-text files.
