We are proud to present not only the first commercial game available on MirthKit, but the first commercial game ever to be released with full source code.

Available on Ubuntu, Windows, and soon OSX, Fight Back is the expansion to our August release, Finity Flight, and represents a path yet-untraveled for gaming. It is the first direct hybridization of commerce and the open source philosophy. However, Finity Flight: Fight Back is not open source software, and this distinction is important.

First, some background. MirthKit, which is the online arcade Fight Back is published on, is the endeavor of a group of friends who want to change the way games are made. We are tired of the current game industry, and we aim to bring more power directly to the individuals who are passionate about making games.

That said, Finity Flight: Fight Back is a proof of concept for our efforts. With it, we are boldly proclaiming, “Yes, the passionate game creator does hold the power to be successful.”

Finity Flight: Fight Back is not open source, but it comes close. When you buy Fight Back for $11.99, you automatically receive all of its code and assets. You are free to modify the game as much as you please.

The reason it is not justifiable to say Fight Back is open source is because you are only allowed to be redistribute changes through MirthKit’s arcade. To reiterate, you are always free to publish your changes through MirthKit (you can even sell them), but users will have to gain access to your work by first purchasing the original game. This policy makes it possible to explore the inner workings of a game like never before, while still allowing the original creator to be rewarded for their work.

We believe this is a fair sacrifice, and we hope it enables more people who care about openness to make games as a living, as opposed to just as a hobby.

Finity Flight: Fight Back

Finity Flight: Fight Back takes place shortly after the events of the original Finity Flight. All alone, you’ve repelled the invaders of earth, but instead of simply waiting for them to come back in greater numbers, you are taking the fight to their home turf.

Fight Back takes place in space, and adds to the original game with 15 new levels, a four new boss levels, four new enemy variations, and new unlockables.

Finity Flight: Fight Back is now available for $11.99 on MirthKit.
