Swp is a continuation of JFSW with many extra's.
I have put together a complete installation setup but had to borrow another site as my site is still down.
Read the installation info.
Just install it, copy the Sw.grp file into the Swp folder from the CD and get the Sw_Hrp.zip file and put that in the main folder.
Start SwpStartup.exe and play RW or whatever you want.
It includes RW3, Taiwang, LoNukem and 8 excellent user maps.
