Well, after the "success" of the original Lost Soulsphere, I looked back at it and found a few things I wanted to change. I messed around, and I came up with this. The Gold Edition has alot of new stuff, such as better music, enemy sounds, and a whole lot more. See below for the complete list of changes from the original.
Risen, for the idea. The people on the Doomworld forums for complaining about how Map07 sucked, which inspired me to do a better version, anyway. :P
