Good old God Mode. Ever since a small company called Id Software started using the key word "GOD" as an invincibility cheat (beginning with ''VideoGame/CommanderKeen''), the term God Mode has migrated as a catch-all term for cheat-code based invincibility in video games.

There are legitimate reasons for having the capability in a game, for playtesters who are trying a particular level and want to stress-test certain parts of a level without having to worry about being killed while testing, and similar such activities. Because they can be used in some very complicated games to allow someone to get past an intractable problem, people (customers) expect most games to have some sort of God Mode in order to allow them to play and finish a game they might otherwise consider {{unwinnable}}.

The term has also become popular as shorthand for NighInvulnerability in other contexts, usually in a cynical tone. For example, to say that somebody is using God Mode in a multiplayer game is to suggest that he/she is using a cheat program. This is also the origin of why apparently grossly-overpowered characters are known as GodModeSue. The term has also become popular within various role playing communities, where it's sometimes called the similar term "{{God Modd|ers}}ing" (think "modifying" as opposed to "mode" for pronunciation). Saying that somebody "God Modes" in a tabletop game is to suggest that he/she basically refuses to allow anything that negatively impacts him. However, the term "godmoding" is viewed a bit more neutrally than "[=godmodding=]" and could just as easily refer to when the characters are given a free pass on potential death for whatever reason.

The GodModeSue is a type of character named after this trope. Not to be confused with [[http://www.godmodeonline.com the webcomic of the same name]].

!!Examples:

* Id Software almost always include a God Mode out of tradition.
** In the VideoGame/{{Doom}} engine, [=God Mode=] (which is also the function of the Invulnerability Sphere, except that it tints your screen in silver as well as giving you the [[GlowingEyesOfDoom glowing God Mode eyes]]) only protects against [[NighInvulnerability 1,000 damage per shot]]. Anything above that and, [[LudicrousGibs well]]...
*** Without damage hacks, the only source of damage that can possibly do this is telefragging, and monsters usually cannot do this to a player. All bets are off on the last level of ''Doom 2'', however.
*** The [=ZDoom=] port for Doom actually have the "Buddha Mode" cheat from ''Half-Life 2''.
* ''VideoGame/HalfLife1'' has a God Mode. ''VideoGame/HalfLife2'' adds in "Buddha Mode" just for good measure, which allows you to take damage but never lets your HP fall below 1, effectively making you immortal. It has been known to mysteriously fail on occasion, which is a deeply jarring event.
** Funnily enough, this applies to ''VideoGame/TeamFortress2'' as well--Buddha mode, at least. While the basic God Mode appears to be cut out, Buddha mode ''is'' available on servers with cheats enabled. You can stand in front sentry guns and jump on sticky bombs all day long and get several Scouts' worth of blood shot out of you to no ill effect. Note, however, that you will be struck dead and either [[LudicrousGibs reduced to flying scraps of outfit and body parts]] or [[BlownAcrossTheRoom sent flying]] the moment you get nailed by a CriticalHit.
** The ''{{Magic The Gathering}}'' card Worship also works this way, provided you control both it and a creature card.
*** Speaking of Magic: The Gathering, [[http://gatherer.wizards.com/Pages/Card/Details.aspx?printed=false&multiverseid=191313 this is probably a good example of god mode]], seeing that it effectively ''makes you immortal'' as long as you control it. [[CriticalExistenceFailure The moment it gets destroyed, however...]]
** The conclusion of the ''Half-Life 2''-based webcomic ''Webcomic/{{Concerned}}'' revealed that [[spoiler:Gordon Frohman had been under the influence of the Buddha cheat from the beginning, thus handwaving his ability to survive massive injuries [[RuleOfFunny for the sake of comedy]]. He dies when he accidentally turns it off]].
* ''All'' of id's Quake engine games have a God Mode, including those which inherited it by licensing it, as Valve did with the first Half-Life. All Unreal engine games have the same god mode. In earlier games, this was simply left available to anyone who knew how to drop down the console; later games' cheats had to be enabled in a configuration .ini file. This has pretty much become standard FPS games on other game engines as well.
* Raven Software's ''Jedi Knight II'' also has a God Mode accessible through the console. But, in the final boss fight, there is a beam of energy in the middle of the room. The game essentially turns god mode on for about a minute for whoever walks into the beam, meaning once the effect's time is up, you'll be vulnerable whether or not you had god mode on before you touched the beam.
* ''{{Rise of the Triad}}'' takes the concept quite literally. The pickup called "God Mode" makes you slightly taller and allows you to smite enemies in one shot as well as making you invulnerable. You also make 'Godlike' yawns [[MostAnnoyingSound that get annoying very quickly]]. The game also contains a more traditional God Mode cheat code.
** ''ROTT'' also features a "Dog Mode" power up which makes you shorter, hairier and quadrupedal, with a chargeable bark attack that can disintegrate every enemy on screen. [[NoAnimalsWereHarmed You are also invincible]], once again. Effectively, it's even better than God Mode, as your small size grants access to secret areas in some maps.
* The ''VideoGame/{{Warcraft}}'' games, as well as ''VideoGame/StarCraft'', all have this as a cheat code. The ''Warcraft'' games also let you deal overwhelming damage that will typically kill enemies in one shot with it activated. ''VideoGame/WarcraftIII'' and ''[=StarCraft=]'' disable this in multiplayer, for obvious reasons. In ''[=StarCraft=]'s'' case, it's not pure invulnerability. Instead, enemies' weapon damage is reduced to zero. There are still several ways in which your units can be killed, though.
** ''VideoGame/WarcraftII'' and ''[=StarCraft=]'' both have flaws in their god mode codes. In ''Warcraft II'', the code works by giving your units incredibly high armor values; however, magical damage bypasses armor, so units like Death Knights remain a threat. In ''[=StarCraft=]'', not only do instant-kill attacks still work on your units, but because units not under your control can't do damage, certain in-game cutscenes will essentially freeze (as the game is waiting for a unit to be sufficiently damaged before continuing) and any map where enemy units are fighting each other will wind up with a huge glut of enemy units uselessly fighting and almost nothing left to go your way.
* ''{{Okami}}'' has an item you can obtain at the beginning of the {{New Game Plus}}, assuming you collected all 100 Stray Beads in the previous playthrough, that grants Amaterasu invincibility, infinite ink, and attack power that is increased tenfold when equipped. This can make the {{New Game Plus}} a literal [[{{Pun}} God]] [[DontExplainTheJoke Mode]].
** Rather appropriate, as Amaterasu ''is'' a goddess.
* Various games that use no clip. With no clip on, you can walk through any object and person since they just go through you and any attack also goes through you. Because of this, you're pretty much invincible.
* ''{{RuneScape}}'''s first ever grandmaster ranked quest allows the player to access a literal God Mode after touching the [[spoiler:Stone of Jas,]] an item which is said to have created and/or boosted the power of many of the games current deities.
* ''Videogame/GodOfWar'' subverts the trope by having "God Mode" as an unlockable once you beat the game - it's merely the hardest difficulty level. The sequel ups the ante by having "God" difficulty available at the start with its hardest difficulty being unlockable under the moniker "Titan Mode."
** In the third installment it gets renamed once again, this time being called "Chaos Mode".
* Both ''VideoGame/TheElderScrollsIVOblivion'' and ''VideoGame/{{Fallout 3}}'' have a god mode, though most of the time it's activated because of its infinite carrying capacity when looting.
** The developers apparently noticed this use, since both ''VideoGame/{{Fallout New Vegas}}'' and ''VideoGame/TheElderScrollsVSkyrim'' have a second cheat called "Demigod Mode", which removes your weight limit and give you infinite ammunition/action points (FNV) or infinite stamina/magicka (Skyrim), but ''doesn't'' make you immortal; you still take any damage you would normally take.
* ''VideoGame/MegaMan3'' is somewhat infamous for being able to use the second controller to god mode Mega Man in various ways. It seems this was used for playtesting and just never removed. Of course, when 3 gets added to collections, this trick is patched out.
* [[Franchise/SonicTheHedgehog Super Sonic]], a plot-based EleventhHourSuperpower in later games, has always led to the true ending of any game it's in, but in ''[[VideoGame/SonicTheHedgehog2 Sonic 2]]'', ''[[VideoGame/Sonic3AndKnuckles 3 and Sonic & Knuckles]]'', once earned, it is a legitimate God Mode, with Hyper Sonic, Hyper Knuckles and Super Tails taking it further.
** You can still die from getting crushed, falling into bottomless pits, drowning, and sadistic pits that are too deep for you to jump out of.
** It's returned to being playable in levels in ''VideoGame/SonicTheHedgehog4''.
** ''VideoGame/SonicColors'' lets you play as Super Sonic in levels too, and even gives you an automatic S-rank for that level if you do so. ''VideoGame/SonicGenerations'' also has unlockable Super forms for both Classic and Modern Sonic that are also usable in the levels.
* ''VideoGame/MassEffect1'': After enabling the console, there are a number of cheat codes that let you obtain just about everything in the game. Money, XP, guns, armor, new abilities beyond those in your Class. Two codes give you a [[TakeThat yellow]] set of armor with 8000 shields and 99% damage resists and a geth assault rife that has [[{{BFG}} 25,000 damage]] per shot.
* ''NeverwinterNights'' on single-player allows you to tell the DM to give you stuff. XP, items, gold, invincibility, etc. etc. etc.
** You can also open up the campaign modules in the toolset and insert hilariously broken items. Among the funniest abilities to abuse are ''spell name'' on hit for items and ''spell name'' on getting hit for armour, allowing you to have (among other things) a sword that summons a badger every time you hit someone with it.
** ''KnightsOfTheOldRepublic'' has a similar system, but if you do so it points out that you cheated every time you load a game after having cheated in it.
* The God Mode code in the original ''[[VideoGame/DarkForcesSaga Dark Forces]]'' was LAIMLAME.
* Using id's God Mode codes in {{Descent}} would reduce your shields and energy levels to 1. Using ''any'' cheat codes flashes [[NoFairCheating "Cheater!"]] on screen.
* The original ''VideoGame/JazzJackrabbit'' had a cheat that set the temporary invincibility parameter to maximum, meaning it would eventually fail. There was also a cheat to make your ''enemies'' practically invincible.
* Enabling 'All Guns', 'Invincibility', 'Infinite Ammo', and, if you want, 'Invisibility' on [[VideoGame/GoldenEye1997 GoldenEye]] allows you to become almost like Jesus, Rambo and your character James Bond in one. You then have the chance to smite the wicked who dare try to stop you with any weapon you damn well feel like. Granted, these cheats do have to be unlocked by performing timed stunts so incredible that you've already proved you don't need them at all.
* Inversion: ''VideoGame/MushihimeSama Futari'' has a "God Mode" in its Black Label version... except this God Mode was a HarderThanHard difficulty level, implying that one would have to be a god in order to beat it.
* In ''VideoGame/TheSims'' series, you can use money cheats to make yourself filthy rich. The first game had no aging, so you could pretty much do whatever you wanted, the second game had an aging off cheat, and the 3rd game even has it under options. Thus you could create a person who lives forever and has unlimited money.
* The creative mode on ''VideoGame/{{Minecraft}}'' is sometimes referred to as "God Mode". You can fly and have access to the complete inventory including things you can't get in survival, like eggs that spawn mobs. In addition, the only way you can die is by falling into the void and even then, you can survive if you enable flying quickly enough.
* ''VideoGame/StarTrekEliteForce II'' had a neat side effect to including unlimited ammo when activated, and it's not unlimited on reserve ammo, it's unlimited on [[{{BottomlessMagazines}} magazines]] as well, this actually causes an odd animation bug with the phaser sniper rifle, which it was supposed to blend with a reload animation since it had one shot per magazine.
* The Sega Genesis game ''{{F-22 Super Raptor}}'' had an invincibility setting on the game's startup menu. It basically made the plane immune to any damage it took and prevented it from crashing.
* In VideoGame/NewSuperLuigiU, [[PromotedToPlayable Nabbit]] is functionally this. While he can't use powerups, he is completely immune to all damage that doesn't [[OneHitKill immediately kill you]] (BottomlessPits, [[LavaIsBoilingKoolAid lava]], [[TheWallsAreClosingIn being crushed]], and running out of time), plus a few InvincibleMinorMinions that knock him back. He can be played in single-player by holding down the ZL button (B on a classic Wii remote).
* ''SlamScape'' has a ''very'' easy cheat that made you completely invincible to absolutely everything in the game from explosions to being ''squished'' in a pneumatic press. It actually made the game a lot funner because of the way you could bounce around and use mines to RocketJump, and was pretty much the only way you'd be able to play a level for more than [[GlassCannon 30]] [[FakeDifficulty seconds]] [[NintendoHard anyways]].
* ''Roleplay/DestroyTheGodmodder'' is a forum game based completely off of this trope, with the posters attempting to kill aforementioned godmodder being the entirety of the game.
* ''VideoGame/TheMatrixPathOfNeo'' has an in-game cheat that unlocks The One mode, where Neo is really in [[InvokedTrope God Mode]] and can't be killed.
