So, TeeJay, known as TeeOS, has been kind enough to help me out and make a map for the Tornado Mod server!
I was trying to start SDK last night to meet with myself failing horribly, and decided to close the topic before a decision was made to continue the map or not.
The map teejay is making is non destructable, which means the tornado CANNOT break any of the houses or the gas station.
I gave TeeJay a layout of the map and he is working on it right now, thanks and credit to him for making the map!
I also will be hosting this map, and it is using HL2 Textures, so I assume you need the game for that, and I'm possibly going to upload the map if it cannot download everything without the map.
