Best Free Linux Games Worth Playing
You install Linux for control, then wonder if you can still play anything. The library is larger than it used to be, and much of it runs without Wine, without tithing, and without a loud GPU. Every game on this list links to its official page or the current Steam catalog.
Why free Linux gaming works in 2025
The old complaint was that Linux had no games. The newer complaint is that it has too many and many are indie experiments. Both miss the point.
Valve’s Proton means thousands of Windows-only titles run through a compatibility layer that is now good enough that you often forget it is there. Steam itself has a native Linux client and a growing catalog of free-to-play titles that need no compatibility layer at all. On top of that, the open-source community has been shipping native games for two decades.
The catch is that “free” covers three different models: free as in open source, free as in free-to-play with optional cosmetics, and free as in the full game with no payment needed. I will tell you which is which for every entry.
Before you install anything
You need a Steam account and the native Linux client. Install it from your distro’s repository or download the .deb from Valve’s site. In Steam’s settings, enable Steam Play for all titles so Proton handles Windows-only games.
For open-source titles not on Steam, Flatpak is the cleanest install path. Run the flatpak install command for the freedesktop platform runtime once if it is missing, then add Flathub as a remote.
Many games below run on integrated graphics. A few, like War Thunder and Dota 2, want a discrete GPU for high settings.
Strategy and tactics
If you want to invest serious time building a civilization or commanding an army, start with these.
Battle for Wesnoth
Battle for Wesnoth is the game I point people to when they say open-source strategy is a toy. It has a single-player campaign that runs sixty hours, a multiplayer mode that still has active servers, and a unit balance that has been refined for two decades.
You command elves, dwarves, and undead across hex-based terrain, and the fog-of-war mechanics mean a careless advance will cost you your best units. It is free as in freedom and free as in money. Install it from your distro’s repository or via Flatpak.
0 A.D.
0 A.D. is the open-source Age of Empires you have been waiting for. You guide a civilization from the village phase to the imperial phase, managing wood, food, metal, and stone while fending off neighbors who would rather burn your farms than trade.
The graphics are still improving, the sound design is excellent, and the multiplayer community is active. It is free and open source, with no microtransactions and no account required. Download the installer from the official site or find it in many distro repositories.
Freeciv
Freeciv takes the Civilization formula and strips it down to a clean, fast, multiplayer-friendly core. You found cities, research technologies, wage wars, and negotiate with AI opponents that are genuinely difficult on higher settings.
The interface is utilitarian, but the game supports custom rulesets and maps, and it runs on hardware that would choke on Civilization VI. It is free and open source, and it has been in active development since 1996.
Mindustry
Mindustry is the game I did not expect to still be playing months later. You build conveyor belts, smelters, and turrets on a 2D grid, mining resources while waves of enemies try to destroy your core.
The campaign teaches you the mechanics through a planetary conquest arc, and the sandbox mode lets you design factory layouts that would satisfy a Factorio veteran. It is free and open source, with a $5 desktop version on Steam that unlocks nothing but supports the developer.
Shooters and action
From arena shooters to MOBAs, these are the competitive titles that still draw crowds.
Xonotic
Xonotic is what Quake III would look like if it had been maintained for two decades. You drop into an arena with seventeen weapon types, a movement physics system that rewards bunny-hopping and rocket-jumping, and a community that still runs nightly tournaments.
The single-player bot matches are a decent way to learn the maps, but the heart of it is online. It is free and open source, with no account required beyond the server browser.
Dota 2
Dota 2 is one of the busiest free games on Steam for a reason. Teams of five heroes destroy each other’s bases across a map that has remained strategically deep for over a decade. Every hero has four abilities, the item shop changes with every patch, and the skill ceiling stays high enough that professional players still discover new techniques.
It is free to play, with all heroes unlockable from the start. Cosmetic items cost money, but they change nothing about how the game plays. It runs natively on Linux through Steam.
Team Fortress 2
Team Fortress 2 turned eighteen in 2025 and it still has a daily active player count that embarrasses many new releases. The nine-class system means you can play as a flamethrower-wielding maniac, a medigun-wielding doctor, or a spy who disguises himself as the enemy’s heaviest hitter.
The cartoon art style has aged well, and the community servers run everything from competitive 6v6 to 32-player mayhem. It is free to play on Steam, with cosmetic items available but never required.
Alien Arena: Warriors of Mars
Alien Arena takes the Quake engine aesthetic and drops it onto Mars. You fight aliens across industrial bases and Martian canyons, with a weapon set that includes a railgun, a launcher that fires homing rockets, and a laser gun that cuts through armor.
The single-player campaign is short but intense, and the multiplayer servers are active enough to find a match on weekends. It runs natively on Steam for Linux.
War Thunder
War Thunder is a vehicle-combat MMO that covers World War II and the Cold War. You fly fighters, drive tanks, and sail destroyers across maps based on historical battles.
The simulation means you cannot just point at the enemy and fire. You manage energy, lead your targets, and watch your six for someone who learned the same trick. It is free to play on Steam, with premium vehicles available but not required for competitive play.
Unvanquished
Unvanquished is the open-source Tremulous you remember, rebuilt with a modern engine. Humans versus aliens across large maps where one team builds structures and the other evolves into heavier forms.
The alien team crawls and flies, the human team shoots and medics, and the balance between the two has been refined over a decade of community feedback. It is free and open source, with no account required beyond the server browser.
Racing and simulation
When you want to drive, fly, or fish instead of shooting, these are the ones that work.
SuperTuxKart
SuperTuxKart is the Linux answer to Mario Kart, and it is better than it has any right to be. You race as Tux across tracks that include a space station, a jungle temple, and a pirate cove.
The items include nitro bombs, bowling balls, and a grappling hook that yanks you to the front of the pack. The single-player campaign unlocks tracks and karts, and the split-screen multiplayer works with a controller. It is free and open source.
Fishing Planet
Fishing Planet is the game for people who want to play something that is not about shooting. You cast a line into photorealistic water, choose your bait based on the species you are targeting, and reel in fish that fight back with unexpected fight.
The free version gives you enough gear to enjoy the game, with paid DLCs for additional locations and equipment. It runs on Steam for Linux through Proton.
Endless Sky
Endless Sky is the open-source Escape Velocity you wish someone had remade. You fly a spaceship across a galaxy of hundreds of star systems, trading cargo, fighting pirates, or running blockades for factions that remember whether you helped them last time.
The 2D graphics are clean, the ship customization is deep, and the community has built total-conversion mods that add new species and new galaxies. It is free and open source.
Open source standouts
These games are free as in freedom and free as in money. No accounts, no microtransactions, no catches.
SuperTux
SuperTux is the 2D platformer that Linux has been shipping in its repositories for years. You play as Tux, running and jumping through forests, caves, and castles while collecting coins and stomping enemies.
The physics are tight, the level design is clever, and the game runs on a Raspberry Pi without breaking a sweat. It is free and open source, with no dependencies beyond SDL2.
Veloren
Veloren is the open-source voxel RPG that looks like someone fed Minecraft through a fantasy novel. You explore a procedurally generated world with friends, fighting dragons, mining ore, and building structures that persist on the server.
The multiplayer is seamless, the combat is action-oriented, and the game is still in active development with monthly updates. It is free and open source, with no account required beyond the server list.
VoxeLibre
VoxeLibre is the open-source Minecraft clone that has evolved past its origins. You mine, craft, and survive in a blocky world that supports multiplayer servers, custom mods, and texture packs that change the look entirely.
The crafting system has more recipes than vanilla Minecraft, the mob AI is more sophisticated, and the game runs on the Luanti engine, which means it launches on any Linux distro without a Java dependency.
Warsow
Warsow is the arena shooter that treats movement as a weapon. You dash, slide, and wall-jump across bright, cartoonish arenas while picking up rockets, railguns, and plasma rifles.
The trick-jumping community keeps the skill ceiling high, and the daily trick-jumping competitions are their own spectator sport. It is free and open source, with no account required beyond the server browser.
Warzone 2100
Warzone 2100 is the open-source RTS that shipped in 1999 and got a second life when its source code was released. You command a post-apocalyptic army across a campaign that spans the American Southwest, building bases, researching technologies, and salvaging enemy wreckage for parts.
The 3D engine has been modernized, the multiplayer is active, and the game runs on hardware that would struggle with a web browser. It is free and open source, and it is available in many distro repositories.
Survival and sandbox
When you want to build, scavenge, or explore without a shooting gallery attached.
Naev
Naev is the open-source space exploration game that has been in development long enough to have its own lore. You pilot a ship through a universe of factions, trading cargo, taking missions, or becoming a pirate if the mood strikes.
Combat happens live, the economy is dynamic, and the community has built total-conversion mods that add new storylines. It is free and open source, with no dependencies beyond SDL2 and OpenGL.
Tank Force
Tank Force is the arcade tank game that takes the old Battle City formula and adds online multiplayer. You command a tank across thirty-six rounds of increasing difficulty, picking up items that speed your shots, thicken your armor, or let you destroy terrain.
The split-screen mode is the draw, letting you and a friend fight through the campaign together. It runs on Steam for Linux through Proton.
Star Conflict
Star Conflict is a space MMO that gives you a spaceship and points you at other players. You choose between three classes, each with distinct weapons and roles, and you fight in PvP arenas, PvE missions, and open-world sectors where the law of the strongest applies.
The free version gives you access to all ships, with premium cosmetics available but not required. It runs on Steam for Linux through Proton.
Dead Maze
Dead Maze is a 2D survival MMO set in a zombie-infested world. You scavenge for food, craft weapons, and build barricades against the undead while other players do the same nearby.
Death is permanent, the crafting system is deep, and the pixel art has a mood that sticks with you. It is free to play, with a premium subscription available for cosmetic perks. It runs on Steam for Linux through Proton.
When a game will not start
A common failure is a missing 32-bit library. Steam games that ship as 32-bit binaries will refuse to launch on a pure 64-bit system. Run the dpkg command to add the i386 architecture, then install the mesa and libc6 32-bit libraries.
The next common failure is Proton not being enabled. In Steam, go to Steam → Settings → Compatibility and check “Enable Steam Play for all titles.”
The third is a missing Vulkan driver. If a game crashes on launch, check that your GPU driver supports Vulkan by running vulkaninfo. The output should show a GPU name, not an error.
Commands to run this week
- Install Steam and enable Proton: install the steam package, launch it, then go to Settings → Compatibility → Enable Steam Play for all titles.
- Install the open-source standouts in one line: use flatpak to install SuperTuxKart, Wesnoth, and Freeciv from Flathub.
- Try the game you would not expect to work: install Mindustry from Steam, play the first campaign mission, and see whether the factory clicks before the first wave hits.
