Here is my third add-on of Wolf3d, Ipank7000's Mapset (SOD Version).
It has 21 new levels and you need your own registered Audio, vswap SOD to play this
mapset (see readme file for further informations).
You can download it in Here (Mediafire).
I hope you enjoy it! .
P.S. I don't know why but i think make SOD map is harder than make Wolf3d map.
