''Defiance'' is a MassivelyMultiplayerOnline ThirdPersonShooter developed by Trion Worlds, released in April 2, 2013 and serving as a tie-in for the [[Series/{{Defiance}} TV series]].

!!''Defiance'' provides examples of:
* AttackItsWeakPoint: Pretty much the only way you can damage bigger enemies.
* AutoRevive: You have a self-revive that recharges over time.
* [[GameBreakingBug Arkfall Breaking Bug]]: A current problem that can come up is that sometimes, during major Arkfalls, one of the smaller ones won't complete despite the objective being completed, therefore making the Arkfall unable to be completed, making everyone's efforts useless.
* BigDamnHeroes: The Arkfall system turns players into this. During major Arkfalls the first stage is 4 or more smaller events, it's quite common for a single or pair of players to be trying to hold the line at one and be reinforced by two dozen players riding in on [=ATVs=], dune buggys, and Dodge Challengers.
** Can also be something of a Subversion as well: One player who knows what they're doing is easily capable of beating a minor arkfall challenge. The two dozen cavalry who ride in to the rescue then subsequently turn all the enemies into outright bullet sponges with orders of magnitude more health than they used to have.
* BodyHorror: The result of getting hit and killed by an Infector.
* BrokenBridge: At what's left of the Golden Gate Brigde, there is a very large mech. Getting too close gets you blown to hell. Eventually you get access to an ICBM that blows it to bits, letting you advance into what's left of San Francisco.
* BugWar: Anytime a large arkfall occurs with the primary enemies being hellbugs. Expect battle zones to be filled with car sized bugs duking it out with literally dozens of ark hunters.
* CrapsackWorld
* CarFu: You can kill most low level enemies by running them over. It even levels up your driving skill with that vehicle type!
* CyberneticsEatYourSoul: 99ers, a group of miners, turned psychotic after getting cybernetic implants - replacing more and more of themselves until they were over eighty percent machinery. It's implied the original psychosis came from an external third party, however.
* CycleOfHurting: Grenade launcher using enemies can do this to you if you're not careful and stand still when fighting them.
* GravityBarrier: The hills around San Fransisco are set up in a way that guides you through the main storyline. A decent vehicle will help you get past them later, if you're interested in scaling them.
* HealingShiv: The Bio-Magnetic Gun, or BMG. It can either drain energy from enemies or heal the user and their allies.
* InvisibleWall: The dark areas on the map edged with a yellow line are this. Sometimes they don't quite match up.
* InsufferableGenius / ItsAllAboutMe: Von Bach all the way. From his introductory scene he paints himself as an arrogant know-it-all, and imposes himself as future savior of Earth due to him having a Ark core. He also repeatedly hits on various female [=NPCs=] like Cass Dukar and Ara Shondu, in a manner that suggests they ''owe'' him for having the Ark core and being the possible savior of Earth.
* ItsUpToYou: Justified when you fight Nim Shondu; you are the only one with an EGO and everyone else is [[HoldTheLine holding off Dark Matter]].
* MonumentalDamage: The broken Golden Gate Bridge is shown in loading screens, and eventually, seen in person. Also, there's the fact that ''everything south of SF'' and the ''whole East Bay'' is uninhabitable, which means that the Bay Bridge, San Mateo Bridge, Dumbarton Bridge, SFO, etc. are all simply ''gone.''
* MoreDakka: As you progress in the game, your simpler weapons have some crazy counterparts, like a grenade launcher that shoots grenades that blow up into six more grenades, Sub Machine Guns that can unload a 50 round clip in under three seconds, and Double-tapping sniper rifles.
* NotUsingTheZedWord: They're "Infected" or "Afflicted".
* RandomEvent: Everything from arkfalls to enemy roadblocks.
* RandomNumberGod: The above-mentioned Random Events make the RNG very unforgiving during racing. Since the races take place on open terrain, the random events can interfere, potentially screwing up a Gold Medal time by dropping a Hellbug in your path.
** Events will also appear in areas where an open-world PVP Shadow War is occurring, even right on top of one of the control points being fought over.
* ShortRangeShotgun: Played straight and averted depending on the type of shotgun. Some are slug based and give up straight damage for a considerable range increase, whereas others are effectively useless beyond five feet but kill almost anything dead in one salvo. Still others are essentially misnamed grenade launchers.
* ShoutOut: If a weapon looks like it's inspired by Film/{{District 9}}, it probably is-according to one of the concept artists, the art director was a huge fan of it.
* UnflinchingWalk: Subverted and lampshaded. You, Jon Cooper and Torc Mok walk away from a major demolition mission. Torc turns around to look, Jon says that you don't do that only for Torc to ask what's the point of big explosions if you don't enjoy them.
* ZombieApocalypse: The plague from the show supposedly causes this in the game. Jarring in that no such zombies or "afflicted" were in the show.
