SWars is still very much in development. You can contribute to make the game better, sooner. Both programmers and non-programmers can help.
Contributing is easy - just join the swars-general mailing list and see what's going on. Ask questions and people will be able to provide you with some direction. Also, read on below to get some idea about what needs to be done.
If you're not a software developer, there's plenty to do. Right now, mostly research. SWars has the potential to scale up to providing a very rich, intricate universe in which we can battle for domination of the Inner Sphere. However, to enable it to do this, it needs a lot of data. This is where you can really help.
SWars needs information about personalities, combat-units and political, military, research and espionage organizations of the Houses, Clans and independent states.
So, join the swars-general mailing list and dive in!
