The AMX Mod was a plugin running under Metamod that allowed scripts to be written for the servers. It got its name from the filename extension of compiled Pawn files, which stands for Abstract Machine eXecutive. In 2007 the AMX Mod project was merged into the related AMX Mod X, which had more features.
