Go beyond the infinite in these cosmic PC games.
The year is 2020 and despite how futuristic that sounds, us average folks probably won’t be headed to space for a weekend getaway any time soon. Until such a day as we can all escape Earth on a whim, here are some of the best games set in space to take you out to the unknown without actually leaving your room.
Whether you want to explore strange new worlds, seduce weird aliens, or become a feared galactic bounty hunter, there’s a space game for everyone on PC, and the following are currently the best examples you can play right now.
Outer Wilds
(Image credit: Mobius Digital)
Year 2019
Developer Mobius Digital
Link Official site
A first-person open world game about exploring a small solar system full of weird planets and odd cosmic phenomena. The catch? You’re trapped in a time loop, giving you just 20 minutes to explore at a time. Outer Wilds is reminiscent of games such as Her Story and Obra Dinn in the way you piece a puzzle together by discovering and connecting small, often seemingly unrelated details.
The Outer Worlds
(Image credit: Obsidian Entertainment)
Year 2019
Developer Obsidian Entertainment
Link Official site
Not to be confused with Outer Wilds, which is also a space adventure and also on this list, Obsidian’s latest RPG is a comedic action RPG that hearkens back to the studio’s days working on Fallout. You and your companions will hop around a solar system full of literally colorful environments and figuratively colorful characters. Corporations are the big bads of the retro space future where you’ll shoot up aliens, choose dialogue, and generally make a mess of every planet you show up on if it suits your fancy.
Homeworld Remastered Collection
Year 2015
Developer Relic/Gearbox Software
Link Official site
One of the best singleplayer RTS campaigns ever made, and beautifully remastered by Gearbox. The sight of thousands of your ships streaking across the game’s vividly colourful space-scapes is hugely dramatic. And battles are tense and tactical, with many types of ship to command, including colossal battleships. The Remastered Collection looks great on modern PCs and comes complete with the original Homeworld and its sequel.
Observation
(Image credit: Devolver Digital)
Year 2019
Developer No Code
Link Official site
The space station Observation has broken away from its Earth orbit and is drifting somewhere near Saturn. Its systems are malfunctioning, a fire has broken out, and the on-board artificial intelligence, SAM, is acting strangely. Things are not looking good for Dr. Emma Fisher, the reluctant hero of this sci-fi thriller from the studio behind Stories Untold. But what’s interesting about Observation is that you don’t play as Fisher. Instead, you play as the AI.
Surviving Mars
Year 2018
Developer Haemimont Games
Link Steam
Leaving Earth behind, humanity heads to Mars to start a new colony: and you’re in charge of it. Your new civilisation will grow from one small dome in the Martian desert to a bustling, sprawling off-world metropolis. But just make sure you don’t run out of oxygen or power, because on this ruthless planet it’s a death sentence for every citizen under your control.
Tacoma
Year 2017
Developer Fullbright
Link Official site
The crew has mysteriously abandoned the Tacoma lunar transfer station, and you’ve been sent to investigate and recover its precious AI, Odin. This atmospheric sci-fi mystery from the makers of Gone Home is wonderfully written, with a cast of rich, nuanced characters telling a compelling story through interactive AR recordings. Exploring the hyper-detailed station is a delight thanks to the game’s extraordinary attention to detail, and the more you learn about Tacoma, the deeper the mystery gets.

Objects in Space
Year 2019
Developer Flat Earth Games
Link Official site
This unique twist on the space sim shares the trading and exploration elements of games such as Elite Dangerous, but feels more like commanding a submarine. You don’t see space itself; just a series of utilitarian rooms full of screens and machinery. There’s a lot to manage, and you play several roles at once: pilot, engineer, comms officer. But despite the limited view of your surroundings, you still feel like you’re hurtling through space in a starship.
Elite Dangerous
Year 2014
Developer Frontier Developments
Link Official site
An entire galaxy is your playground in this space sim. Starting with a basic ship and a handful of credits, you shape your own destiny. Do you become a fearsome pirate? A master trader? An explorer? The beauty of Elite is being able to play in a way that suits you. From thrilling dogfights to gentle exploration, there’s something for everyone. And its ships are all an absolute dream to fly, whether it’s a nimble fighter or a heavy duty cargo hauler.
EVE Online
Year 2003
Developer CCP Games
Link Official site
Live another life—in space! There’s nothing else like EVE Online on PC, a massively multiplayer RPG where everything is controlled by players. It’s a living galaxy in which thousands of capsuleers fight, trade, mine, and explore together. Break away from the relative safety of your police-patrolled starting system and you’ll find a ruthless, cosmic Wild West, where piracy, espionage and scamming are rife. Whether you’re fighting in a massive space war, where thousands of real-world dollars hang in the balance, or just exploring New Eden on your own, EVE is an unforgettable experience.
Everspace
Year 2017
Developer Rockfish Games
Link Steam
When you die in roguelike Everspace, you’re dead. But money earned carries over and can be spent on upgrades, which means you’ll be more powerful for your next run through the cosmic gauntlet. And these perks keep adding up, allowing you to travel deeper into space, and more boldly, with every successive attempt. It’s a compelling loop, and when you die you’re never frustrated: just excited to start again, wondering how far you’ll make it this time.
Dead Space
Year 2008
Developer EA Redwood Shores
Link Steam
Space is the perfect setting for a horror game, and Dead Space is, next to Alien: Isolation, one of the best examples of the scary sci-fi genre. Engineer Isaac Clarke is sent to investigate a stricken ‘planet cracker’ ship, the USG Ishimura, and finds the craft overrun with hideous, fleshy monsters. Taking cues from Alien and, quite blatantly, cult favourite Event Horizon, the first game in the series is still the best. The increased focus on action in the sequels killed it.
Star Wars: Empire at War
Year 2006
Developer Petroglyph
Link GOG
Developed by Petroglyph, a studio founded by Westwood veterans, this real-time strategy is one of the best Star Wars games on PC. The streamlined interface and accessible systems might turn off some hardcore strategy fans, but in the thick of its chaotic, thrilling land and space battles the game is irresistible—especially if you’re a Star Wars fan. And hero units like Darth Vader and Luke Skywalker only add to the excitement.
Battlefleet Gothic: Armada 2
Year 2019
Developer Tindalos Interactive
Link Official site
A real-time tactics game about giant spaceships clashing in the Warhammer 40,0000 universe. Battles take place on a 2D plane populated by capture points and asteroid fields, and the ships handle like giant, deadly cruise liners. You can unleash fighter and bomber squadrons, launch torpedo barrages and laser attacks, and board other ships. The space battles are involving and spectacular and the campaign is satisfying—especially for 40K fans.
Endless Space 2
(Image credit: Amplitude Studios)
Year 2017
Developer Amplitude Studios
Link Official site
A stylish game of galactic conquest. Not the broadest or deepest 4X strategy game on PC, but an atmospheric afternoon-killer that blends strategic decision making with a beautiful presentation. Set in a vivid sci-fi universe, the game lets you explore mysterious star systems, discover the secrets of ancient races, build colonies on distant planets, and encounter aliens to meet and conquer.
Heat Signature
Year 2017
Developer Suspicious Developments
Link Steam
In this top-down sci-fi action game you board spaceships and use an array of weapons and gadgets to take out the crew. The genius lies in how much creativity you’re given to play your own way, inspired by the best immersive sims. And how you react to the chaos that erupts when your presence on the ship becomes known makes Heat Signature a powerful anecdote generator. Things might not always go to plan, but that’s just part of the fun.
Duskers
Year 2016
Developer Misfits Attic
Link Official site
Despite being viewed entirely through a retro-futuristic computer interface, Duskers is one of the scariest, most tense sci-fi horror games on PC. In it you pilot a fleet of drones searching derelict spaceships for fuel, upgrades, and clues about why the galaxy is so mysteriously devoid of life. The ships you board are crawling with strange creatures, which makes looking for clues in those narrow, dark corridors an especially nerve-racking experience.
Destiny 2
Year 2017
Developer Bungie
Link Official site
Bungie’s addictive FPS/MMO hybrid features some of the prettiest alien landscapes on PC. From the forested ruins of Earth and the vast seas of Titan, to the red jungles of Nessus and the volcanic Io, every location is a pleasure to loot-and-shoot in. The endgame doesn’t have the iron grip it perhaps should, but sci-fi fans will get a kick out of this vivid, colourful setting.
The Dig
Year 1995
Developer LucasArts
Link GOG
A mission to divert an asteroid heading for Earth goes awry, sending a group of astronauts to a distant, seemingly abandoned world. Some of the puzzles are maddeningly obscure, even for a LucasArts point-and-click adventure, but the colourful, bizarre planet feels genuinely alien. Great voice acting too, with X-Files star Robert Patrick playing the lead character.
Universe Sandbox 2
Year 2014
Developer Giant Army
Link Official site
This space simulator lets you become an all-powerful cosmic deity, manipulating replicas of real galaxies and solar systems and witnessing the (often catastrophic) results of your meddling. Increase the mass of Jupiter and you’ll see the rest of our solar system being sucked into it, or delete the Sun and watch Earth and the other planets drift away confused.
Event[0]
Year 2016
Developer Ocelot Society
Link Steam
Stranded alone somewhere near Jupiter on an old luxury starship, your only hope of returning home is an AI that has serious emotional problems. You interact with Kaizen using your keyboard, and sometimes it’ll be willing to help you. But then it’ll change its mind and decide the best thing to do is close the airlock and trap you outside the ship until you run out of air. A clever adventure with the understated mood of a ’70s sci-fi film.
Mass Effect 2
Year 2010
Developer BioWare
Link Steam
If you’ve ever fantasised about being Captain Picard, in command of your own starship, exploring the galaxy, meeting weird aliens, being confronted with cosmic dilemmas, then Mass Effect 2 is that in game form. It’s part Star Wars space opera, part brilliant Star Trek episode, and one of the best sci-fi games on PC. It doesn’t have the freedom of Elite and is largely a linear experience, but it takes you on an unforgettable journey around the galaxy, visiting bizarre planets and getting involved in the lives of the aliens who live on them. We love the whole series, but we all agree that this is our favourite.
Stellaris
Year 2016
Developer Paradox
Link Official site
Developed by Paradox, of Crusader Kings and Europa Universalis fame, this sci-fi epic puts the ‘grand’ in grand strategy. Explore the universe, form alliances with alien factions, and engage in the odd large-scale space battle. The multitude of systems makes Stellaris a powerful story generator, and you never know what strange beings you’ll meet among the stars.
Alien: Isolation
Year 2014
Developer Creative Assembly
Link Official site
Amanda Ripley, daughter of Ellen, is hunted through a dilapidated space station by a xenomorph in this incredible survival horror. Taking its cues from Ridley Scott’s original 1979 film, it’s a masterpiece of slow-burning tension. And the station itself, Sevastopol, is a great example of lo-fi sci-fi, with chunky retro-futuristic tech and eerie flickering lights. One of the most faithful movie adaptations ever, and a great horror game in its own right.
No Man’s Sky
Year 2016
Developer Hello Games
Link Official site
This is one of the most dazzlingly colourful sci-fi universes on PC, and being able to seamlessly transition from space to the surface of a planet is an impressive technical feat. The addition of features like base-building and a mission system in recent updates give you a lot more to actually do when you touch down on these worlds, and the procedural generation algorithm has been tweaked to make for weirder, prettier planet surfaces.
Star Wars: TIE Fighter
Year 1994
Developer Totally Games
Link GOG
A rare opportunity to be the bad guy in George Lucas’s beloved space opera. With a variety of Empire-themed missions—dogfights, escorts, attacking capital ships—and a story to follow, it’s one of the best Star Wars games LucasArts ever published. Of course, you can replace this entry with Star Wars: X-Wing if you’d prefer to play as the boring old Rebel Alliance.
FTL: Faster Than Light
Year 2012
Developer Subset Games
Link Steam
FTL mixes turn-based and real-time strategy together to capture the experience of captaining a Star Trek-style spacecraft. It’s a strong roguelike, too, with a backdrop of a familiar yet fun sci-fi universe that comes with its own semi-humorous lore and a neat set of narrative beats that make the journey to its finale endlessly exciting. Being able to name your ship and crew makes it all the more heartbreaking when they die together in enemy space.
Wing Commander: Privateer
Year 1993
Developer Origin Systems
Link GOG
Best Sci Fi 4x Games List
Fans of the series will argue endlessly about which Wing Commander is the best, but we love Privateer’s darker feel. It’s a rich sandbox in which you can be a mercenary, a pirate, a merchant, or a mix of all three. You jump between systems looking for bounties to hunt and ships to rob, and the first-person dogfights are a thrill. There’s a linear story, but the real joy lies in doing your own thing and carving your own path through the stars.
EVE: Valkyrie
Year 2016
Developer CCP Games
Link Official site
If you have a VR headset, this is the game to play on it. In Valkyrie you get to experience EVE Online’s famous space battles from the more intimate perspective of an individual fighter pilot. The feeling of being strapped into a cockpit, hurtling through space at immense speeds, is a visceral one. And the combat has been tuned specifically for virtual reality.
Kerbal Space Program
Year 2015
Developer Squad
Link Official site
Wrestle with gravity and the laws of physics as you build your own spacecraft and attempt to explore the cosmos. A robust, compelling sandbox of possibilities that’s as funny as it is clever. Escaping Kerbin’s atmosphere and landing on the Mun (without exploding) for the first time with a ship you’ve built yourself is about as satisfying as PC gaming gets.
Take On Mars
Year 2013
Developer Bohemia Interactive
Link Official site
If you like your space games a little more grounded, try Arma developer Bohemia’s Take On Mars. It’s a space exploration and colonisation simulator largely based on real astro-science. You can build a Curiosity-style rover and explore the surface of the red planet or construct your own Martian colony. A game for folk who want the sci without too much of the fi.
Sins of a Solar Empire
Year 2008
Developer Ironclad Games
Link Official site
Mixing real-time strategy with 4X elements, Sins is a game of galactic conquest. Choose a faction, gather resources and become a mighty space-lord. Commanding its real-time wars is thrilling, but combat isn’t always the answer: you can use diplomacy to conquer systems too. A refreshingly slow-paced RTS with some truly massive space battles to stare slack-jawed at.
Space Engineers
Year 2013
Developer Keen Software House
Link Official site
Harvest asteroids for building materials then craft them into floating bases, flyable spaceships, and more besides. You can hover around the map with a jetpack or build a gravity generator to walk safely on the surface of bigger asteroids. One of the best co-op build-’em-ups on PC.
Starbound
Year 2013
Developer Chucklefish Games
Link Official site
Terraria-esque survival with a science fiction twist. Hop between randomly generated planets on a starship, hunt alien creatures for food, build colonies and underground bases, and try not to die in the process. A brilliant sci-fi sandbox with a charming art style. Playable races include robots, beings made of solar energy, ape-like creatures, and colourful wingless birds.
Best Sci Fi 4x Games Ever
SpaceEngine
Best Sci Fi 4x Games 2020
Year 2010
Developer Vladimir Romanyuk
Link Official site
Do you like feeling small and insignificant? Then play SpaceEngine, which features, incredibly, the entire universe. Or at least the bit we know about. Focus on Earth, then pull back at top speed, and you suddenly become aware of how you’re on a tiny speck of dust hurtling through an endless void. The tech is remarkable, allowing you to travel effortlessly between galaxies and land on planets. But besides exploring, there isn’t much else to it.
