After the most players of Tremulous left, most of the servers went offline. The only two servers running now are New Edge and acidtu.be. The acidtu.be server is fully modded, with different textures, buildings and even AI bots. However, this server is located in Asia so players from Europe will have a high ping. Edge is the most played server, because it is located in Amsterdam (and the most of the players are from Europe) and because of the mods. Edge contains a wide variety of changes, and it is very different from the original (vanilla) Tremulous. It includes new buildings for both teams, new upgrades, new maps, a new alien and much values have been changed to balance the game. The server is still in development, with every few weeks an update with new stuff.
