AMX Mod X

AMX Mod is a scripting mod for the administration of Half-Life servers. The mod was initially developed in the pre-Steam era of Half-Life and it has been ported to the steam versions.

Half-Life and its mods (Counter-Strike, Day of Defeat, Team Fortress, etc.) are is the game with most dedicated servers for multiplayer games. Around a half of these servers with an administration mod use AMX Mod, that is around 20,000 servers (of those who log their stats). The beauty of this mod is its flexibility: anyone can make their own scripts for their servers, making it a customized server administration program. Of course, they can do many other things, like implementing games within the game, inside their server. If the person writing the scripts is experienced, he/she can even create his/her own GUI menus for gamers or administrators to use. That gives administrators all the control and power on their server. There are also several add-ons for the most popular Half-Life mods. Really, if you have a server, you have to decide between AMX and MetaMod, and it is only matter of what you need for the server.
