Easily one of the best open source games around, Mindustry from AnukenDev just had a MASSIVE new release out that took quite some time to make.

It's free, it's open source and it's absolutely awesome. Mindustry just had an almighty update bringing with it huge changes and it's just as awesome as ever.

Mindustry, a game that mixes in Factorio with Tower Defence and then goes wild from there is a fantastic example of how good a free and open source game can be.

When you get hooked on a game like Mindustry, it's hard to put it down and play anything else so please send help.

Oh no, this is going to be very bad for my free time. It was bad enough with Factorio having a huge update recently and now Mindustry is available on Steam.

Could this be your next time sink? Mindustry merges together Tower Defense style gameplay with production chains from the likes of Factorio.

Mindustry is a free and open source Tower Defense game that pulls in elements rather similar to Factorio and it seems like it could be quite good.
