Quake Live is a first-person shooter (FPS) video game by id Software designed to run on x86-based computers running Microsoft Windows, Mac OS X and Linux that is downloaded and launched via a web browser plugin. It is a variant of its predecessor, Quake III Arena (Q3A), and is the second game in the Quake series to have a "Teen" rating from the ESRB, the first being Enemy Territory: Quake Wars.
Quake Live is free to download and play. Additionally, there are subscription options that include more arenas, game types and game server options.
The gameplay of Quake Live consists of players attempting to frag more of their opponents than any other player or team in a given match. This is achieved by navigating a 3D environment and shooting other players with a variety of weapons, while collecting health, armor, weapons, ammo and various power-ups. As players get more advanced, they use other tricks and techniques such as rocket and strafe jumping.
Quake Live was released as a free version of Quake III: Gold (Quake III and its expansion pack, Team Arena) available only through a web browser. Quake Live is backed financially by in-game advertising from IGA Worldwide. Skill-based matchmaking is powered by a "metagame engine" developed by GaimTheory. Development of the match-making system was taken on by id Software after GaimTheory's collapse.
Game modes 
- Duel: Player versus player (1-on-1) combat. Whoever gets the most frags before the time is up wins.
- Free For All (FFA): Players engage in a match, where everyone fights for themselves. Whoever hits the frag limit first wins and ends the game. When the time limit expires, player with the most frags is the winner.
- Instagib: Free for All mode or TDM where players start with only a Railgun. There are no powerups around the map (i.e. health, ammo, weapons). Instagib servers are unranked.
- Team Deathmatch (TDM): Same rules as Free for All but in this mode, two teams fight each other.
- Pro Team Deathmatch: a variation on Team Deathmatch for higher skilled players where some of the server settings are changed, such as the respawn time of weapons increased from 12 seconds to 30 seconds.
- Capture the Flag (CTF): Each team has a base, holding a flag. To earn points and win the game, a player must take the opposing team's flag and return it to their own base, while his team's flag is secure at his own base.
- InstaCTF: Similar to Instagib (i.e. railgun, lack of powerups, etc.) but in a CTF format. Instagib CTF servers are also unranked.
- 1-Flag CTF (1FCTF)
- Clan Arena (CA): Teambased gameplay where everyone starts fully equipped with full armor and weapons. When fragged, the player must wait for the next round to begin. Players can rocket jump and plasma climb with no health penalty. Players on the same team suffer no damage from their own teammates' weapons.
- Freeze Tag (FT): (subscription only; free around Christmas) A team based game mode combining elements of Clan Arena and Team Deathmatch. Rather than spectating when one is fragged, one is instead "frozen", and cannot respawn until a player on their team "thaws" them by standing adjacent to them for several seconds. When all players on one team are frozen, the other team wins the round.
- InstaFreeze (IFT): Similar to Instagib (i.e. railgun, lack of powerups, etc.) but in a FT format. Instagib FT servers are also unranked.
- Harvester (HAR)
- Domination (DOM)
- Red Rover (RR)
- Attack & Defend (A&D)
During the QuakeCon 2008 keynote speech, John Carmack stated that Quake Live has no plans to allow user-made modifications, but they have hired successful Quake III mod authors to help them with their project. The majority of the maps are based heavily on originals from Quake III Arena, Team Arena and popular user-made maps. Newer map additions even include maps from previous Quake titles, such as 'The Winter's Edge', which is almost identical to the famous Quake II map Q2DM1.
On August 3, 2007, at QuakeCon 2007, id Software publicly announced their plans to release a free browser-based Quake III game titled Quake Zero. In early 2008, the title was officially renamed to Quake Live due to a domain squatting issue.
During late 2008 and early 2009, Quake Live was in an invitation-only closed beta. A handful of players were selected to begin the testing of the beta and were later allowed to invite a limited number of friends, whom, in turn, were permitted to send out invitations of their own. On February 24, 2009, the game progressed from closed beta to open beta, which caused an increased amount of traffic on the web server. Queues were organized to limit the stress and prevent the overloading of the servers. Within the first six hours after launch over 113,000 user accounts were created. The queues were removed after several days, and the servers were then upgraded to handle the larger volume of traffic.
Once Quake Live exited its closed beta stage, it was to be funded partially by in-game and website-based advertisements. IGA Worldwide were contracted by id Software to handle this aspect of the game's marketing. Problems with this model surfaced almost immediately with the announcement by the advertising agency that they were struggling as a result of the financial crisis of 2007–2010. In March 2009, the agency admitted that sale was a possibility if further investments were not forthcoming. With the acquisition of id Software by ZeniMax Media, the in-game and web-based advertisements for Quake Live changed noticeably, and began heavily advertising in-house for Bethesda Softworks products.
At QuakeCon 2009, John Carmack stated publicly that their financial scheme for the game had so far failed to provide sufficient income to keep the project in the black. As a result, he announced that a premium subscription service was being planned:
"The in-game advertising stuff has not been big business. That's not going to be able to carry the project... Quake Live is gonna be Quake Live for the foreseeable future... It's only just now that we're going to be able to put it to the test."
Marty Stratton, id Software's Executive Producer, has commented that:
"The plan is to completely integrate the ability to start and manage private games directly through QUAKE LIVE, utilizing all of the friends, awareness and notification features we have available through the site. This ability will be the cornerstone of a QUAKE LIVE Premium Service that will be offered for a small monthly fee (likely less than $5 per month)."
On August 6, 2010, the game left its public beta period, and "premium" and "pro" subscription options were announced. On September 11, 2012, id Software introduced subscriptions in one, three, six, and twelve month increments, along with the ability to purchase redeemable gift tokens.
Quake Live runs an updated version of the id Tech 3 engine, granting a few graphical improvements like bloom. In addition to usability changes, Quake Live has a new, more streamlined HUD. The game is also censored to remove blood, gore, and satanic references that were found in Quake III Arena and is the only game in the series that was developed by id Software internally to be rated T by the ESRB.
Quake Live registration of a user account is available on the Quake Live website and free to anyone wishing to play. Currently supported platforms include Internet Explorer 7+, Mozilla Firefox 2+, Safari 3+, and Google Chrome web browsers running on Windows XP, Windows Vista, Windows 7, Mac OS X 10.4+ (Intel processor only), and Linux. During the registration process the game and required browser plug-in is automatically downloaded. Updates to the game are continually released and automatically installed as the user logs in. In addition to browser support, there is an unofficial 3rd party dedicated game client QLPrism, which utilizes Mozilla Prism.
Competitive play 
Being largely similar to Quake III Arena, which is renowned for its extensive use in professional electronic sports, Quake Live has seen inclusion in many tournaments worldwide. In recent years, however, the game has experienced a decline in the number of tournaments due to waning popularity.
