¡Pueblo indolente! ¡Cuán distinta sería hoy vuestra suerte si conocieseis el precio de la libertad! Pero no es tarde.

Flare is an open source, 2D action RPG licensed under the GPL3 license. Its game play can be likened to the games in the Diablo series.

While the core engine is written in C++ with SDL2, there is an easy to use modding interface. Using the modding interface, it’s possible to create entirely new games. On the Mods page, you can find games made by the Flare team, as well a few select community projects. For more information on creating your own mods, see the Modding section of the Get Involved page.

The game tells the story of a world destroyed by a conflict between robots and their human masters. Play as Tux in a quest to save the world from the murderous rebel bots who know no mercy. You get to choose which path you wish to follow, and freedom of choice is everywhere in the game.
