Download methods,

Primary method: Most recommended one to stay fully up to date.

Download TortoiseSVN from here - http://tortoisesvn.net/downloads Install it, restart your computer if asked.
Make a new folder anywhere on your computer. (Mine is E:/SVN Folders/Red Alert)
Right click on the new folder and click "SVN Checkout..."
Enter " https://edukeredalert.svn.sourceforge.net/svnroot/edukeredalert " as the URL and leave the other options as is and click "OK"
Once it has finished downloading DO NOT ATTEMPT TO PLAY IT IN THIS DIRECTORY
Instead, right click the folder and go to "TortoiseSVN > Export "
Choose the location you would like to play DNRA in. I placed mine in (C:/Duke Nukem/)
Then click "OK", it will then export the folder to the directory all you need to do once it has finished exporting is to place a copy of your "DUKE3D.GRP" in the folder and read the damn readme! Wink
To update your copy of DNRA is even easier, right click you SVN folder you made and click "SVN Update" (No really thats all you have to do Smiley) If there is an update available it will download it, once it has finished downloading just export the folder as you did above.
A video tutorial on how to use SVN is located here if my explanation was terrible. Just rember to use the URL above and not the one shown in the video. http://www.youtube.com/watch?v=SQgetjwgF9M

Secondary method: If all of the above sounds way to hard.
You can download a version of 1.0 here - http://www.mediafire.com/?gnmyjmktmyn 71.73 MB
Note: Bug fixes etc will always be addressed first on the primary download method which is why I recommend it, you can also get the latest versions of the Polymer HRP and EDuke32 using this great tool.
