This selection follows LinuxLinks’ June 5, 2022 roundup, which required games to be free to download, openly licensed, playable even if incomplete, not dependent exclusively on proprietary data, and built with openly licensed or Creative Commons media. That is the roundup’s selection standard, not a fresh verification of every project’s current licensing, downloads, or maintenance. Check the official project page before downloading.

How to choose among these free RTS games
Real-time strategy games unfold continuously rather than in turns. They commonly ask you to gather resources, build an economy or base, and command forces. These ten games vary in how much they emphasize those elements: some focus on historical or science-fiction warfare, while others foreground programming, settlement economics, or large multiplayer battles.

The ten games
0 A.D.: ancient civilizations and historical warfare
0 A.D. is the natural starting point if you want to build a civilization in an ancient-world setting. Its official overview describes gathering resources and building a military force, while the project says the game remains under development. Wildfire Games announced Release 28, “Boiorix,” on February 18, 2026; the release adds a new faction alongside 14 other factions. That is a release-specific count, not a promise that the game is complete.

#1 Best Overall
- Stratego is the strategic game where you challenge your opponents in the heat of battle
- Your task is to capture your opponent’s flag while defending your own
- Lead your men into battle, every move is crucial
- Includes 2 x 40 pre-printed playing pieces, Game board, Screen and 2 sorting trays for the pieces

The project describes the game as free to download with no freemium model, in-game advertising, or catch. Its platform notes say Windows 10 and 11 are supported, macOS versions below 10.15 are dropped, and an AppImage is provided for Linux. Check the release page for the download appropriate to your system.
Bos Wars: a futuristic setting
The 2022 roundup describes Bos Wars as a futuristic RTS. That makes it a possible pick if you want a science-fiction setting, but the cited information does not establish its current availability or detail its mechanics. Check the project’s current official channels before deciding whether it suits your system or preferred way to play.
Colobot: Gold Edition: program the bots
Colobot: Gold Edition stands apart from conventional army-command games by letting players program bots using CBOT. It is the most obvious choice here for someone who wants a programming element alongside the RTS premise. The available description does not confirm the project’s present version, maintenance, or platform support, so verify those details before downloading.
Globulation 2: a different approach to micromanagement
The roundup’s distinguishing point for Globulation 2 is its unusual approach to micromanagement. If you find the constant handling of individual units in many RTS games tedious, that difference may be worth exploring. The cited information does not support a more detailed account of its current mechanics or availability.

MegaGlest: armies across several factions
MegaGlest is presented as a faction-centered game. The 2022 roundup describes control of armies across seven factions, giving it a broad fantasy-strategy angle. Treat that faction count as the roundup’s description rather than a current figure; the available information does not verify the present count or project status.
Rank #2
- EXPLORE THE ISLAND OF CATAN: Settle the uninhabited island of Catan by gathering resources, building infrastructure, and nurturing trade relationships.
- STRATEGY AND COMPETITION: Compete with 2-3 opponents to expand your settlements and cities while managing resources and avoiding the robber.
- TRADE, BUILD, AND SETTLE: Use brick, wood, wheat, ore, and sheep to construct roads, settlements, and cities in your race to 10 victory points.
- REPLAYABLE AND ENGAGING: With a modular hexagonal board, no two games are the same, offering endless strategic opportunities and replayability.
- FOR FAMILIES AND STRATEGY ENTHUSIASTS: Designed for 3-4 players, ages 10 and up, CATAN 6th Edition is perfect for family game nights and friendly competition. Add the CATAN 5-6 Player Extension (sold separately) to expand your game to 5-6 players.
OpenHV: pixel-art science fiction
OpenHV is identified in the roundup as a pixel-art science-fiction RTS. Its clearest differentiator in the available description is its visual style and setting. Inclusion in a 2022 list does not establish current maintenance or availability, so check its project page for current information.
Seven Kingdoms: Ancient Adversaries: a strategy hybrid
Seven Kingdoms: Ancient Adversaries is described as combining RTS play with a Civilization-like turn-based strategy element. That hybrid framing may appeal if you want more than continuous battles and base-building. The available information does not independently verify its current download or licensing details.
Warzone 2100: campaign, research, and custom units
Warzone 2100 is the strongest supported pick here for a post-apocalyptic campaign paired with unit design. Its project sources describe a campaign, offline skirmishes, research across a tech tree of more than 400 technologies, and customizable unit design. Multiplayer supports up to 10 players, according to the project repository. The homepage displays version 4.7.0.
Online games require players to use matching versions and avoid incompatible mods. The project’s FAQ lists minimum requirements of 1 GB RAM, OpenGL 3.1 or later, and about 150 MB of storage. It recommends 4 GB or more of RAM, OpenGL 3.3 or later or Vulkan 1.1 or later, and about 1 GB of storage when campaign videos are included. These are the project’s stated requirements, not results from comparative hardware testing.
The project states that its source code, downloads, and features are free, with no in-app purchases, subscriptions, or ads. For current platform and download details, use the official homepage.
Rank #3
- Bird Collecting: You are bird enthusiasts - researchers, bird watchers, ornithologists, and collectors - seeking to discover and attract a beautiful and diverse network of birds to your wildlife preserve.
- Build Your Engine: Gain food tokens via custom dice in a birdfeeder dice tower, lay eggs using egg miniatures in a variety of colors, draw from over 170 unique bird cards and play them.

- For families, solo gamers, and game groups alike: This medium weight, set collection and hand management strategy game for 1-5 players has a 60-90 minute playing time with only a 6 minute setup time. Great game for couples, solo gamers, 2 players, family, and friends. Includes swift-start pack for first time player guidance.
Widelands: settlement economics and military strategy
Widelands is described as an economic and military simulation similar to Settlers II. Its appeal is the settlement-management angle: it is the pick to investigate if you would rather think about production and a growing community as well as military forces. The available description does not verify its current mechanics, platform support, or maintenance.
Zero-K: large robot-army battles
Zero-K is the roundup’s choice for large robot-army battles. Its project page lists single-player and multiplayer, including 1v1, 2v2, 10v10 or larger, free-for-all, PvE, and custom missions. That range makes it the clearest option here for readers choosing primarily by multiplayer format. The cited project information does not state a current version, so check the project page for up-to-date details.
What about Beyond All Reason?
Beyond All Reason is not one of the ten games in the 2022 roundup, but its current download page provides a useful reminder that “free RTS” does not mean “lightweight RTS.” The page lists a minimum quad-core 2.7 GHz CPU (or one newer than 2010), GTX 960, and 12 GB RAM. Its recommended configuration calls for 16 GB RAM and an SSD, with 4 GB of free disk space stated alongside that configuration; it also advises 20 GB available for maps, replays, and screenshots. The page lists Windows 10 or Linux and says the game is currently not compatible with Mac. These are the project’s stated specifications, not benchmark comparisons.
Check current downloads and requirements before installing
The list dates to 2022, and the available current project information is uneven: 0 A.D. and Warzone 2100 have dated release information, while the provided descriptions for several other games do not establish present versions, platform support, or maintenance. Use each game’s official project page to confirm the download and license information that applies now. Requirements are not interchangeable across titles, as the published Warzone 2100 and Beyond All Reason specifications illustrate.
