http://code.google.com/p/customwars/The link above will take you to the latest copy of "Custom Wars 2"... or at least to where the release is held

...
Be warned. This IS NOT an official distribution release. This release is basically a test release so that testers and users may see the progress of the game thus far. So, with this release will come bugs. A full list of bugs is within the issue list in the above link, but if you don't wanna go through that... then I'll list the major bugs here.
Bugs-Server system is a little buggy- You might not be able to connect with another person online smoothly for an entire game...
-MapScreen Dilemma- You can't press up/down on the map select screen so use the mouse to select the map (for now)...
To get this game running, all you'd have to do is...
0.25) Go to above link...
0.5) Click the Download tab
0.75) Download "Unofficial Distribution 1.0"
1) Extract the .rar file (using WinRar or extraction equivalent).
2) Open CWDist folder.
3) Double-click (or open) the [Custom_Wars.jar] file.
It should work right out of the package. If not, then you'd probably need to check if you have the latest version of Java installed. There was a documentation on how to get the .jar files running deep in the archives of CW. However, I'll look for it and post up the link when I find it. In the meantime, if there is a problem with the distribution, post here and I'll see what I can do.
