To celebrate Flotilla turning 10 years old, Blendo Games announced today that it's been made open source.

Flotilla is a mixture of a space exploration adventure, with turn-based tactical combat and branching events when you do the exploring. It only gained Linux support last year, when Ethan Lee ported it from XNA to the FNA project. Some of the features:

No adventure is the same: Whenever you begin an adventure, the universe is randomly populated with characters, upgrades, and encounters.

There is no "up" in space: Explore the tactical richness of full 3D movement. Watch your angles and flank the enemy from all directions.

Configure your fleet: Find loot throughout your adventures, and install upgrades and artifacts to your flotilla of ships.

Play with a friend: Grab a buddy and play through the adventure cooperatively in splitscreen.

Blow up your friend: In the Skirmish Mode, set up custom fleets and battle human or computer-controlled enemies.

It's now under the zlib license, which is highly permissive so you can do pretty much anything with it. However, like a lot of open source release it does not include the assets so you still need to buy a copy for things like art/textures, audio and so on. This is a really good way to do it, keep the code open for people to fix it up and keep it alive but the developer can still easily earn monies with it.

Find the source up on GitHub, the game is available from itch.io and Steam.
