Mindustry is a free tower defense game released under Open Source (GPL-3.0). It runs on Windows, macOS, Linux, Android, iOS, needs about 250 MB of disk space, and requires no account, payment or trial. On a computer, the fastest route is the PlayBound Launcher. On a phone or tablet, use the official store or site instead.
One-click install
PlayBound fetches the official release — no third-party mirrors.
Install the PlayBound Launcher, then find Mindustry and press Install. The launcher downloads the official release, unpacks it and creates a shortcut. This is the fastest route and it never uses third-party mirrors.
Alternatively, download Mindustry directly from the official site at https://mindustrygame.github.io. Always download from the official source — third-party mirrors of free games are a common malware vector.
Official releases are published on GitHub at github.com/Anuken/Mindustry/releases. Pick the newest stable release matching your operating system.
Mindustry is also on Steam and is free there. Open the store page and press Play Game to add it to your library.

Run the downloaded installer and follow the prompts. If Windows SmartScreen warns about an unrecognised publisher, that is normal for open-source projects without a paid code-signing certificate — choose More info, then Run anyway.
macOS
Open the downloaded .dmg and drag the app into Applications. On first launch macOS may refuse to open it as unidentified — right-click the app and choose Open to approve it once.
Linux
Check your distribution's package manager first, which is usually the easiest route. Otherwise download the AppImage from the official site, mark it executable and run it.
chmod +x *.AppImage && ./*.AppImageLaunch the game and look at the settings menu before your first session — resolution and control defaults are worth checking. Mindustry needs roughly 250 MB of free disk space.

The desktop version on Steam, itch.io and the official site is entirely free and open-source under GPL-3.0, with no purchases or advertising. The iOS and Android store listings are paid, which is the only place money changes hands.
The core loop is very similar — conveyor logistics, resource chains and throughput optimisation. The differences are that Mindustry is top-down 2D, uses bounded maps rather than one endless world, and makes combat central rather than incidental. Sessions are much shorter as a result.
Yes, both co-op and competitive PvP, on free public servers or your own. Multiplayer costs nothing and requires no account.
Around 250 MB, which makes it one of the smaller games in the catalog. It runs comfortably on old laptops and low-end hardware.
It is one of the better entry points. Bounded maps and a guided campaign introduce concepts gradually, and a failed sector costs you an evening rather than a month of progress.
Yes. There is a built-in mod browser with a large community library covering maps, schematics, new content and full overhauls, installable without leaving the game.
