Other custom files include models, skins and even complete bots. The custom models again, include some real high quality examples, such as the Alien on the Home Page of this Website, or the 'Lara Croft in Quake 3' model pictured above. Mods, or modifications, change the actual gameplay of the original program, and sometimes add whole sets of maps, skins, sounds, and weapons. One of the first mods, was QuakeWorld , which improved the Online playing qualities of the first Quake game. Clan players specialised as defenders, snipers, and attackers, leading to a number of game mods that encouraged the division of game skills.
Some mods become almost as popular as the original game.
Popular modern mods include Classic CTF, Fortress, Rocket Arena, Freeze Tag, Jailbreak, etc. Some mods, such as Q3 Urban Terror, are total conversion mods - that is, they modify the game almost out of recognition, into entirely new games that exploit the 3D engine of the standard game. But the point is, that these mods, maps, and skins, are produced by the gaming fraternity themselves, and with a little sponsorship, they are usually free - and easily downloadable from the Net. Connectivity M ultiplayer gaming over the Internet can have technical problems. Obviously, fast 3D multiplayer gaming involves a huge exchange of data between computers and the server, which test Internet routes to the maximum, especially when using low speed modems.
