🧑🚀 Survival in Space: How Do Space Games Handle the Dangers of Space?
Surviving in space is no easy task—whether you’re a stranded astronaut, a colony leader on Mars, or a deep-space scavenger dodging cosmic radiation. In real life, space is an unforgiving vacuum filled with hazards like extreme temperatures, radiation, oxygen deprivation, and the ever-present threat of mechanical failure.
So how do video games translate that danger into compelling, immersive gameplay? Let’s break down how different space games tackle the real (and fictionalized) threats of outer space—and where they crank up the tension, bend the rules, or get surprisingly accurate.
🚨 1. Oxygen Management – Don’t Hold Your Breath
“You only miss it when it’s gone.”
Running out of air is one of the most immediate and terrifying threats in space—and many games use it to raise the stakes.
🎮 Games That Do It Well:
- 🔹 Hardspace: Shipbreaker
You’re a salvager cutting up derelict ships in zero-G. Oxygen drains constantly, forcing you to work quickly and return to airlocks.- Bonus danger: Cut the wrong fuel line and… boom.
- 🔹 Breathedge
A dark-comedy survival game that spoofs Subnautica in space. Oxygen is limited, and upgrades are needed to explore further into the wreckage of a doomed ship. - 🔹 Prey (2017) – Zero-G Sections
Spacewalks outside Talos I require monitoring your oxygen while avoiding alien threats. Short, tense, and immersive. - Mechanics:
- Oxygen meters with timed depletion
- Airlock systems and oxygen tank refills
- Environmental leaks requiring patching or rerouting
🌡️ 2. Temperature Extremes – Too Hot, Too Cold
Space isn’t just cold—it’s extremely cold in shadow and dangerously hot in direct sunlight. Few games go deep into thermal survival, but some acknowledge it.
🎮 Games That Touch on It:
- 🔹 Surviving Mars
Players must manage temperature regulation in domes. Without proper insulation, colonists freeze during dust storms or at night. - 🔹 Astroneer (stylized but thematic)
Some planets feature extreme environments requiring upgraded suits or tech to explore safely. - 🔹 The Long Journey Home
A roguelike with temperature-based planetary hazards. Land on the wrong side of a planet and your ship systems start to overheat or freeze. - Realism Score: Medium—often stylized, but adds challenge.
☢️ 3. Radiation – The Invisible Threat
In real space travel, radiation from the sun and cosmic rays is one of the biggest long-term hazards. Some space games build this into the survival loop.
🎮 Radiation-Focused Gameplay:
- 🔹 Kerbal Space Program (with mods)
Mods like Kerbalism or Realism Overhaul simulate radiation exposure during long missions, especially outside Earth’s magnetic field. - 🔹 Osiris: New Dawn
Features solar radiation events where players must find shelter quickly to avoid exposure. - 🔹 Starfield
Some planets are labeled with “extreme” radiation or thermal hazards, requiring upgraded suits to explore safely. - Mechanics Used:
- Suit upgrades for radiation shielding
- Exposure timers and damage over time
- Radiation storms affecting electronics or biology
🔧 4. Equipment & System Failure – Space is Not Forgiving
Whether it’s a busted O2 scrubber or a glitchy life support system, failure in space can be sudden and catastrophic.
🎮 Games That Lean Into It:
- 🔹 Stationeers
Deeply technical survival sim. Players manage atmospherics, power systems, and gas mixes. Forget one valve, and boom—your base decompresses. - 🔹 Heavenly Bodies
You’re a cosmonaut in zero gravity, trying to maintain a broken space station. Every action involves realistic movement and equipment use in microgravity. - 🔹 Hardspace: Shipbreaker
Accidentally cut a coolant pipe or fuel tank and you’ll cause massive chain reactions. Precision is key. - Realism Rating: High in some games, simplified or scripted in others.
💥 5. Decompression & Explosive Risk – One Mistake = Vacuum
Explosive decompression is a staple of space danger fiction—and many games dramatize this well.
🎮 Explosive Moments:
- 🔹 Dead Space
Includes scenes where windows break and the room violently vents to vacuum—one of the most cinematic uses of decompression. - 🔹 Observation (2019)
Realistic portrayals of decompression and pressure regulation in a derelict space station. - 🔹 Among Us (yes, really!)
Being ejected into space as a crewmate is cartoony, but still rooted in a classic sci-fi death trope.
👾 6. Aliens, Anomalies & Fictional Dangers
While not strictly “realistic,” many space survival games throw in alien threats or sci-fi hazards that enhance danger while keeping with the theme.
🎮 Examples:
- **🔹 Returnal – Time loops + cosmic horror
- **🔹 Dead Space – Necromorphs, psychosis, and hostile artifacts
- **🔹 The Callisto Protocol – Bio-engineered mutations on a prison moon
- 🔹 Subnautica: Below Zero – Alien tech and planetary weather while stranded on a frozen moon
These add psychological or unknown elements to survival, reminding us that space is not only dangerous—it’s also unfamiliar.
🧪 7. Food, Water & Human Needs – The Long Haul
In long-term space survival, players must often manage hunger, hydration, and health—turning survival into a full-time job.
🎮 Deep Survival Systems:
- 🔹 Space Engineers (with mods) – Survival mode adds food, air, and waste systems.
- 🔹 RimWorld & Oxygen Not Included – While not strictly space-in-space, they simulate survival colonies with brutal realism.
- Mechanics Often Include:
- Crop growing in space
- Water filtration systems
- Sanitation and psychological stress meters
🧠 Survival Design Approaches: Arcade vs Simulation
| Game | Survival Realism | Focus |
|---|---|---|
| Hardspace: Shipbreaker | 🔥 High | Oxygen, suits, decompression |
| Heavenly Bodies | 🧠 High | Physics-based EVA tasks |
| Breathedge | 😂 Medium | Comedy-driven, basic survival |
| Starfield | ⚖️ Medium-Low | Hazard zones & suit upgrades |
| Stationeers | 🧪 Very High | Full atmospheric simulation |
| Subnautica | 🌊 Stylized | Alien planet, realistic needs |
| Osiris: New Dawn | 🌐 Medium | Radiation, oxygen, gear upgrades |
🌠 Conclusion: Danger Makes It Real
The best space survival games understand that space isn’t just a backdrop—it’s the enemy. Whether you’re fending off freezing temperatures, patching a leak in your hull, or rationing oxygen, the fight for survival turns ordinary tasks into life-or-death challenges.
Some games aim for realism. Others lean into fiction. But all of them remind us that in space, the smallest mistake can be your last.
