Extract the mod .rar file on your PC.
Move the folder pg into your "....\steam\steamapps\common\natural selection 2\" folder.
Right click on ns2.exe and click on send to desktop(create shortcut).
Right click the shortcut select properties.
Find the line called target and after the "....\Steam\steamapps\common\natural selection 2\NS2.exe" add: -game pg.
On my computer the target line reads - "F:\Games\Steam\steamapps\common\natural selection 2\NS2.exe" -game pg
Click the general tab of the properties window.
Change the name from shortcut to ns2 to something like pg or Proving Grounds.
Click OK
Double Click the newly named desktop icon to launch the mod.
When you open server browser, sort by game. If you sort twice (First alphabetically, 2nd time reverse alphabetically) this puts PG servers at the top of the list.
Join as normal.
