Well this is a Western mod that I know I am going to like, several years back I made a Stargate level with Stargate ring platform transporters, check out the stuff inGAME and if you would like it I will need to pull the Radiant build off and old busted computer, but for now the ring platform transporter prefabs are within the ringscft10.pk3 in both .xmap and .map formats.
Tell me what you think about the map.
