--> ''"Untold centuries ago the Vadrigar, the mysterious Arena Masters, constructed the Arena Eternal for their own infernal amusement. Virtually nothing is known of these beings except that they savor the carnage and clamor of battle. As such, they have stocked the arena with the greatest warriors of all time. And you have just joined their ranks."''
-->-- '''From the [[AllThereInTheManual manual]].'''

''Quake III: Arena'' is the third entry in the ''VideoGame/{{Quake}}'' series, launched in 1999.

This time, several warriors from all the corners of the galaxy duked it out in order to entertain the SufficientlyAdvancedAliens, and win the honor of being the most badass warrior of all time. Characters from several of Id's games, such as VideoGame/{{Doom}} and the two previous ''Quake'' games, were present in it.

This game was designed almost exclusively with multiplayer mode in mind. Id had recognized the fact that the deathmatches were easily the most popular thing about ''Quake'' so far, and created this entry as a virtual arena for competitive online matches. The single-player mode contained only a very basic story, and was based around a series of tiers, with the player making its way to the final match against the Champion.

This game received an ExpansionPack in the form of '''Quake III: Team Arena''', made by Id themselves, which was focused in team games. Here you must choose a team and duke it out with the other clans.

Id also released a free web browser version of ''Quake III: Arena'' (that was later turned into a paid Steam-only game in October 2015) called '''[[http://www.quakelive.com Quake Live]]''', which also added many extra maps (especially third-party ones) and some extra game modes. This version was later released on Steam.

And finally there's a UsefulNotes/XboxLiveArcade version called ''Quake Arena Arcade'', which was released December 15, 2010, which has some new maps.

Followed chronologically by ''VideoGame/QuakeIV''. In 2016, it received a direct successor as ''VideoGame/QuakeChampions''.

The game has [[Characters/QuakeIIIArena a character sheet]].

* ArtEvolution: For being in the same engine, many of the ''Arena'' and ''Team Arena'' maps received really big visual changes for ''Live'' compared to the original versions.
** Barely noticeable in ''Team Arena'' itself, but it's still there - starting with the menu design and ending with the minor fact that Callisto has little face animation, unlike the other models.
* ArtificialStupidity: The game uses an AI system based on brushes (firstly used on the Xaero bot mod for ''VideoGame/QuakeII'') instead of waypoint-based systems. This, however, doesn't mean that the bots will play like humans. They cannot jump, use platforms (there's a reason of why Q3 lacks platform-based maps, and uses jumppads instead) and they cannot navigate their way onto items which take some kind of risk to get. This is also a problem in its SpiritualSuccessor ''VideoGame/OpenArena''.
* AscendedGlitch: The Strafe Jump, with a tutorial and training course in ''Live''.
* BatmanCanBreatheInSpace: Some levels are set in space platforms and just a bunch of the characters aren't helmet-less, spacesuit-less humans.
* BeamSpam: The Lightning Gun.
* {{BFG}}: It's a Plasma Gun on steroids, however...
* BloodKnight: In the blurb, it says the gods wanted more entertainment, so they put you and the others there to fight, and even made you immortal so that not even ''death'' would release you from fighting.
* BondOneLiner: The dev team got creative with them, as many bots can attest. This is something which was [[TropeCodifier refined further]] by ''VideoGame/UnrealTournament'' and the like.
** ''Team Arena'' characters rely on "uniformed" voice acting rather than texted chat lines and, as a matter of fact, there's significantly less one-liners than in the vanilla Q3, but they're still here.
* {{Bowdlerization}}: In order to get the "T" rating, ''Live'' had to drop every topic/reference to alcohol, drugs, rear-guards, sex, porn, depictions of violence with animals and Satanism.
* DeathIsNotPermanent: If ''WebVideo/{{Arenas}}'' is any indication, characters are rebuilt between respawns. In the game proper, the bots even lampshade this.
* ChainsawGood: The Gauntlet.
* CherryTapping: The game actually gives you a ''humiliation'' award for killing your opponent with the Gauntlet. This fact makes the otherwise useless Gauntlet a popular weapon, especially in ''Quake Live'', where other players can see how many people you "humiliate" during all your game sessions.
* CompetitiveBalance: In ''Team Arena'', you start as JackOfAllStats, as in any FPS, but in the maps with the Runes, depending on the rune you've taken, you may become:
** FragileSpeedster: Scout. (Negates your armor, and you're unable to pick up armor, but makes you faster)
** MightyGlacier or LightningBruiser: Guard. (You receive the max health and armor, and the health will regenerate to the maximum)
** GlassCannon: Doubler. (Increases your firerate and weapon damage)
** SpoonyBard: Ammo Regen. (Your ammunition regenerates... rather slowly)
* CompetitiveMultiplayer: One of the games that really started the multiplayer craze, it still has a dedicated "professional" competitive community to this day.
* CreditsGag: In the PC version, after defeating [[spoiler:Xaero]], there's a cutscene which shows [[spoiler:him]] turned into stone, and the obvious credit list... [[spoiler:then Slash appears trying to control her rollerblades]].
* DeathTrap: Some Deathmatch levels have these. They range from killing pendulums, to crushing platforms, to death pits.
* DefeatEqualsExplosion: Any player who dies while carrying the Kamikaze holdable powerup. When dying, (and if they're not gibbed) they will produce a huge explosion which shakes the arena.
* DevelopersForesight: In single player, curse at a bot. They'll comment on your potty mouth. Similarly, typing in racist slurs will have them ask if you're some sort of racist. Typing something religious will either get them on praising religion or throwing an insult at you. Really, there's a lot of topics it can handle, even though pretty loosely.
* DummiedOut: More info [[http://leileilol.mancubus.net/cut/q3a.html here]]. Some worthy mentions:
** Vanilla ''Quake III'' has a GrapplingHookPistol, accessible via cheating. It's modeled and works like it should, but its functionality is incomplete.
** ''Team Arena'' has an incomplete UseItem, a Portal device. Like the Grapple, it's modeled, but its functionality is incomplete, and there's no model, sprite or effect for it, leading it to being a weird GameBreaker if added to a map. Should it have been completed with the functionality finished, it would have predated games such as NarbacularDrop and VideoGame/{{Portal}}.
** A minor one, but some bot chatlines were commented out, such as Angel's reactions when she gets killed by a player or kills with a [[SuicideAttack Kamikaze]]. They're a real thing for Fritzkrieg and Pi, however.
* EasterEgg:
** The [[VideoGame/CommanderKeen DopeFish]] [[TheCameo appears on a level]].
** [[Webcomic/UserFriendly User Friendly's Dust Puppy]] appears on another, but you must fall off an edge to see it.
* ExcusePlot: The game's plot goes like this: SufficientlyAdvancedAliens kidnapped some of the greatest warriors and made them fight each other to death and redeath. You die? [[DeathIsNotPermanent They'll respawn you back]]. The best warrior will then challenge Xaero, the Arenas Eternal's champion. In the [=PS2=] version, you get to fight against the tournament's host directly, though.
* {{Flight}}: You can find this item in just one map during a Multiplayer match, but it's also present in some third-party maps as well.
* FollowTheLeader: Alongside ''VideoGame/UnrealTournament'', ''III'' started the multiplayer-focused craze.
* GradualRegeneration: The Regeneration powerup.
* LighterAndSofter: ''Live'' has blood and gore removed, along with the map decorations of corpses, torture victims, and skeletons.
** Other things such as references to drugs, alcohol and sex were removed as well. See {{Bowdlerization}} above.
* LightningGun: The Quake 1 gun returns, but without the "water discharge" property.
* LoadsAndLoadsOfLoading: A pretty painful issue of the [=PS2=] port, in which loadings might span for just as long as two minutes.
* MassiveMultiplayerCrossover:
** This game feature characters from most of Id Software's major FPS games until its release date battling it out for supremacy, such as the SpaceMarine from VideoGame/{{Doom}}, the ''VideoGame/{{Quake}}'' dude (referred to as "Ranger"), and several characters from ''VideoGame/QuakeII'' including the generic Grunt, Bitterman (the protagonist of the main ''Quake II'' game), Major, and a [[GiantMook Strogg Tank]]. The only major missing figure is VideoGame/{{Wolfenstein}}'s B.J. Blazkowicz. (Well, him and VideoGame/CommanderKeen, but then again, HideYourChildren) To make up for it, ''Team Arena'' adds Fritzkrieg, a reconstructed soldier from WWII.
** This also extends to the weapons, as the starting guns are a small version of Doom's chainsaw (the Gauntlet) and Quake II's Machinegun. There're also ''Quake's'' Lightning Gun, (which, sadly, doesn't include the "instant water kill" property its Quake counterpart had) Doom's Plasma Gun, and Quake II's Railgun. ''Team Arena'' also adds a modified version of ''Quake's'' Nailgun (which behaves more like a Shotgun with Nails instead of a rapid-fire Nail shooter) and Quake II's Chaingun.
** AuthorAvatar: After installing the 1.16n patch of the game, you can even play as [[SelfInsertFic some of the developers!]]
** GuestFighter: Bullfrog, the developers of ''Quake III: Revolution'', sure didn't leave the happy owners of this [=PS2=] port without a tasty treat - [[VideoGame/DungeonKeeper The Reaper and The Mistress]] make guest appearances there!
* MidBoss: The single-player portion of ''III'' features one boss per tier, except Tier 6: Sarge, Hunter, Klesk, Anarki, Uriel and [[FinalBoss Xaero]].
* MoreDakka: ''Team Arena'''s Chaingun. The machine gun in vanilla Arena is a lamer version.
* NailEm: ''Team Arena'''s Nailgun.
* {{Nerf}}: The Railgun in ''Team Arena'' and later revisions. It was overpowered in Arena, being hitscan and doing enough damage to reliably kill an opponent in one or two shots. In ''TA'', the weapon gets weaker with distance, making it useless at longer ranges. This was later carried over to vanilla ''III'' by the time of Point Release 1.32.
* NoOSHACompliance: Lampshaded by Gorre, when he dies by lava:
--> ''"Where's the 'Under Construction' sign? Who built this freakin' place?"''
* {{Nostalgia Level}}s: ''Live'' adds some well-known third-party maps to the fray and some obscure console-only ones.
* PaletteSwap: Multiple models have alternate skins, although they all have no more than two team textures. Bolded are the bots available in the vanilla campaign, the console-exclusive bots are in italic.
** '''Bones''' - ''X-Ray''
** '''Doom''' - '''Phobos'''
** '''Sarge''' - ''Krusade'', ''Roderic''
** '''Grunt''' - '''Stripe'''
** '''Hunter''' - ''Harpy''
** '''Klesk''' - ''Flisk''
** '''Slash''' - ''Yuriko'', Grrl
** '''Patriot''' - '''Razor''', ''Id''
** '''Lucy''' - '''Angel'''

** '''Uriel''' - Zael
** '''Visor''' - '''Gorre'''
** '''Major''' - '''Daemia'''
** '''Biker''' - '''Cadavre''', '''Hossman''', ''Slammer'', Stroggo
* PopStarComposer: Front Line Assembly composed some tracks for the main game.
** Moreso Sonic Mayhem, which returns after doing soundtrack for Quake II.
* {{Shareware}}: The demo version came with four levels (Arena Gate -q3dm1-, Temple of Retribution -q3dm7-, The Longest Yard -q3dm17- and The Proving Grounds -q3tourney2-) and five selectable characters (Daemia, Grunt, Visor, Major, Stripe and Sarge as a FinalBoss of sorts).
* ShoutOut:
** The final single-player level, "The Very End of You", is named after a line from "We're In This Together" by Music/NineInchNails.
** The achievement for knocking down enemies in Quake Arena Arcade is called "[[ThreeHundred This Is Stroggos!]]"
** The fourth single-player level is called "The Place of Many Deaths", after a song by Music/MorbidAngel.
** The map "The House Of Decay" from ''Team Arena'' was rechristened as "[[Music/NewOrder Blue Monday]]" in both the Dreamcast version and ''Live''.
* SuicideAttack: By using the Kamikaze item in ''Team Arena'' and ''Live''.
* TimedMission: All of ''Team Arena''[='=]s single-player missions are this, as well as some matches on the main game.
* TimeTrial: Basically to what the singleplayer mode in ''Team Arena'' has been reduced - a series of free-to-choose challenges, in which you need to [[ScoringPoints score points]]. The time bonus, complete with the skill multiplier, deliver the biggest impact on the challenge's final score.
* TournamentPlay: The longevity of the game in the competitive scene eventually led to the development of ''Live''.
* UseItem: Teleporter and Medkit, also Kamikaze and the Invulnerability force field in Team Arena.
* WhyAmITicking: In ''Team Arena'' and ''Live'', hit an enemy with a Prox Mine, (or many, for amplified effect) and in [[YouAreAlreadyDead 10 seconds]], more or less, he will blow into pieces.
* YourMom: Might occur if you try to chat with a bot (any who can reply to your messages, anyway) and actually manage to piss him off.
