Flare, GPL3 lisansı altında lisanslanan açık kaynaklı bir 2D aksiyon RPG'sidir. Oynanışı Diablo serisindeki oyunlara benzetilebilir.

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.
