Game Overview
Life in the battered remains of humanity’s solar system is a constant negotiation between hunger, broken machinery, and creditors who expect payment no matter how close you are to suffocating. Ostranauts is a demanding hard-sci-fi survival simulation set in the same bleak future as NEO Scavenger, where Earth’s collapse leaves corporations, stations, and desperate independents fighting over what remains. You begin as a captain with a messy personal history, limited cash, and either a barely functional vessel or the wreckage needed to assemble one. The mood is oppressive but compelling: every successful salvage job feels like a small victory against an economic system designed to keep you in debt.
Most of your time goes into maintaining a ship that behaves like a real, interconnected machine. You buy components, repair hull breaches, route power, manage fuel and life support, and turn salvaged parts from abandoned craft into something that can survive another trip. Derelicts offer valuable loot, but boarding them means dealing with airlocks, vacuum exposure, hazards, locked compartments, and occasionally hostile survivors. Crew members bring skills and personality problems to the table, so hiring help also means handling injuries, needs, wages, conflicts, and the risk of mutiny when conditions deteriorate. Contracts, trading, scavenging, and careful navigation create the core loop, while poor planning can strand a captain far from safety with no breathable air or money for repairs.
What separates Ostranauts from broader space sandboxes is its intimate attention to the physical realities of owning a ship. Rather than commanding a pristine starship fleet, you live inside a cluttered, customizable junker where every room, battery, engine, door, and storage locker matters. Its interfaces and systems demand patience, and the learning curve is closer to a simulation than an arcade survival game, but that complexity produces memorable disasters and unlikely recoveries. Fans of RimWorld, Space Haven, and NEO Scavenger who enjoy emergent stories, technical tinkering, and unforgiving survival will find a uniquely grimy spacefaring experience here.

How do I update my GPU drivers for this game?
The game won't launch — what should I try?
Check that extraction completed and your PC meets the system requirements. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
