Red Eclipse is a fun-filled new take on the casual first person arena shooter, which lends itself toward a balanced gameplay, with a general theme of agility in a variety of environments.
The project is a Free and Open Source game, built on Cube Engine 2 using SDL and OpenGL which allows it to be ported to many platforms; you can download a package for Windows, GNU/Linux, BSD, and OSX, or grab a development copy from our Subversion repository and live on the bleeding edge.
In a true open source by the people for the people nature, we try to work closely with the gaming and open source communities to provide a better overall experience, aiming to create a game environment that is fun and easy to play, while still having elements to master.
If you think you might have something to contribute to the game or community, please feel free to drop by our Chat or Forums and talk to us directly. We try to maintain a standard of friendly behaviour in our community, so don't be afraid to speak up and have your say in building this game for us all :)
The game is available for free, but please consider contributing a small token to pay for expenses and future improvements.
