I am currently running a test of my first Descent 3 level that I made for more than just my own curiosity. It is an update to the classic Descent 1 volcano level from the Total Chaos set of maps.
The server is on PXO and entitled "Volcano Revisited (beta test)".. my how original. I'll try to keep it running in the evening this week until about 10pm EST, and it'll run longer during this weekend.
Feel free to have a look and have fun. And please post any comments you might have.
