Mindustry
Factory-building tower defense with serious depth.
The PlayBound Bar
Mindustry clears all five: free with no monetisation on desktop, complete and heavily content-rich, actively developed, easily good enough to sell, and open-source under GPL-3.0.
Genuinely free
No trial, no paywalled campaign, no pay-to-win, no cosmetic treadmill. Free means free, forever.
Finished enough to enjoy
Playable and satisfying start to finish today — not a promising alpha you should check back on.
Actively maintained
A release or meaningful commit within the last twelve months. Someone is still looking after it.
Stands on its own merits
Good enough that we would recommend it even if it cost money. Free is not the reason it is here.
Won't disappear
Open-source or self-hostable, so no shutdown, delisting or licence expiry can take it away from you.

About Mindustry
Factorio famously never goes on sale and the developers have said it never will. Mindustry is the answer for everyone who wanted that itch scratched anyway, and it is not a lesser substitute — it adds something Factorio only gestures at.
Mindustry is a top-down factory automation game where the factory is under attack. You mine resources, run them along conveyor belts, refine them through production chains and feed the output into turrets, because waves of enemies are coming for the network you just built. That combat pressure changes how you build. In Factorio a messy layout is an aesthetic problem; in Mindustry a messy layout is a defensive liability, because throughput to your guns is what keeps you alive.
Maps are bounded rather than endless, which turns the game into a series of self-contained optimisation puzzles instead of one sprawling megabase. A campaign sector is an evening rather than a month, and that structure suits people who want a defined objective and an ending. The campaign spans dozens of sectors across two planets with distinct resource sets and enemy behaviour.
Multiplayer is genuinely good and free — co-op building on public servers, and a competitive PvP mode where two teams race to out-produce and then destroy each other. There is a built-in mod browser with a large library of community content, including maps, schematics and full overhauls.
At roughly 250 MB it runs on almost anything, including phones and low-end laptops. The desktop version is entirely free; the mobile store versions are the only place any payment exists.
Why we picked it
Automation games usually ask for a month of your life. Mindustry gives you the same conveyor-belt satisfaction in evening-sized portions, and then makes you defend what you built — which turns out to be a better idea than it sounds. It is also one of the most polished games we list, free or otherwise.
Who it's for
Great if you want
- Anyone who wants Factorio's logistics without the price or the time sink
- Defined objectives and shorter sessions rather than endless bases
- Co-op building with friends, or competitive PvP factory racing
- Low-end hardware — around 250 MB and very undemanding
- Players who want combat pressure to shape their layouts
Look elsewhere if
- You want Factorio's scale and endless single world
- You dislike combat interrupting your optimisation
- You want 3D or first-person building
- You want deep crafting recipe trees; Mindustry's are simpler by design

Frequently asked questions about Mindustry
Is Mindustry free?
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.
Is Mindustry like Factorio?
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.
Does Mindustry have multiplayer?
Yes, both co-op and competitive PvP, on free public servers or your own. Multiplayer costs nothing and requires no account.
How big is Mindustry?
Around 250 MB, which makes it one of the smaller games in the catalog. It runs comfortably on old laptops and low-end hardware.
Is Mindustry good for beginners to automation games?
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.
Can I mod Mindustry?
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.
