Q3A/Quake III Arena

Quake III Arena (or Quake III: Arena), often referred as Quake 3, Q3A or simply Q3, is a first-person shooter published by id Software in 1999.

Its engine, known as id Tech 3, supports OpenGL graphics (and specific support for the "3dfx Voodoo" cards, popular at the time).

Quake 3 and another game released that year (Unreal Tournament) were different from previous FPS because of they didn't have single player "story" game. Previous games had a "deatchmatch" multiplayer game mode, but these two games focused themselves on this game mode. They were a success.

In Quake 3 you can fight against human players over LAN or Internet, or you can play offline against computer-controlled players called "bots".

The game supports additional maps and character models... and entire "mods" that can change various aspects of the game. Many of them have been created by fans. id Software itself created a commercial mod called Team Arena.

id Software released some patches for the game, called PointReleases. Latest version is 1.32c (one has to install the game, then 1.32c PointRelease, and then the 1.32c patch).

It exist a port for the Sony PlayeStation 2 console, which is named Quake III Revolution, and incorporates stuff from both Q3A and Team Arena, with some other twists.

Games derived from Quake 3

Until 2005, various commercial games used licensed (and modified) versions of its engine (for example, Star Trek: Elite Force, or Star Wars: Jedi Knight 2).

On August 19, 2005, id Software released the source code of the game under the GNU General Public License, allowing programmers to use it for free.

So, ioquake3 was born. ioquake3 uses a modified version of the id Tech 3 engine, resolves some bugs and adds various features, like support for IPv6. ioquake3 source code is under GPL, and you can download the installer for free... but to install it, it needs the textures, maps and 3d models from the original Quake 3, and they are still under copyright of id Software (only source code is free). This means that you must buy Quake 3 to be able to install and use ioquake3, and you can't share freely the whole thing.

Since ioquake3 source code is free, it has been used to create OpenArena. OpenArena is totally stand-alone (you don't need the original Q3A) and free: all copyrighted material has been removed, everything has a free license. So, you can play a game very similar to the famous Q3A and use the improvements introduced by ioquake3, at no cost.

id Software itself created a new version of Quake 3, called Quake Live (a working title was "Quake Zero"). It is automatically updated and launched from a plugin in your web browser (web browser that you use to select a server where to play). It is playable for free, but it's not as free as OpenArena is. It requires registration (so each player has got an unique name), and you can play at no charge, but some features, like more maps and the ability to create a server, are available with a payment subscription; you cannot use your own custom models, maps and mods.

Compatibility for additional stuff designed for Quake 3 with OpenArena

See also: FAQ#How can I use maps, models, mods made for Quake 3 Arena?, Manual/Using Mods, ModCompat

You can use additional characters, maps and mods designed for the original Quake 3 Arena inside OpenArena. But some of them could have some problems, for example caused by missing textures, missing maps or missing bots. Please refer to ModCompat page for additional info. In general, mods designed for Q3A v1.27 or later should work.
Additional player models should be complete models (usually, those in pk3 files larger than 1 MB), not simply additional skins for Quake 3 characters. Up to OpenArena 0.8.5, Quake 3 bots are not fully compatible, thus you should avoid adding them to the match, or you should manually fix them to make them compatible, or simply install a specific patch, while waiting for the next release of the game that will include it.
