-->-- The ''VideoGame/SuperSmashBros'' Announcer [[TakeThatAudience telling you just what you are]].

You ran out of [[HitPoints hit points]]. You lost your last life. The character [[EscortMission you're supposed to protect]] has stumbled off a cliff face. Your {{Mons}} have all fainted.

It's '''[[foldercontrol]]

[[folder: Game Over ]]
''' for you.

So now what? The nicest games might just [[DeathIsASlapOnTheWrist let you off with a warning]], less forgiving games might make it so that ContinuingIsPainful or send you back to a checkpoint. If you're [[NintendoHard really unlucky]], then it's back to the start of level for you... [[FinalDeath or even the entire game]].

Of course, if you're really lucky, the game over screen will simply read FissionMailed or the game will [[HopelessBossFight let you continue anyway]].

This is, at its most basic, the condition of having lost the game. Some text or animation appears to let you know you've lost, and there's nothing left to do but start over. You can achieve Game Over by:

* Running out of HitPoints or VideoGameLives. In a game with FinalDeath, this occurs if the main character or a plot-important character dies.
* Failing critical mission objectives (such as letting the target of an EscortMission die)
* Certain circumstances (covered in {{Unwinnable}}) don't technically result in a game over, but prevent you from continuing further into the game.
* Older arcade games and games that are [[AWinnerIsYou too lazy to give you a special victory screen]] will simply show you the standard game over screen if you just beat the game. Because of course, your game is over in that situation, too. To modern gamers it can be rather jarring to see a screen associated with death being used to indicate success, especially if the music is still there...

In the earliest games, you had to start over from the very beginning, but later games provided a password so you could continue from a later spot, and eventually game saves to fulfill the same purpose more conveniently. Some games also let you 'continue' from the same level you were previously on. Indeed, the game over has been such an {{Omnipresent Trope|s}} that some games use the phrase whenever you have in some way failed, even if this failure does not in any conceivable way end your game.

Some games will even give you a game over screen even if you complete the game, using "Game Over" in a literal sense, as since you've beaten the game, it is now over.

A NonstandardGameOver is a variant that occurs in special circumstances, when you've ''really'' screwed the pooch.

Sometimes the screen is accompanied by a GameOverMan (no, not [[Film/{{Aliens}} Pvt. Hudson]]).

[[CrowningMusicOfAwesome Also the name of a]] [[http://www.youtube.com/watch?v=phwdyzz_IVo single]] by Club Caviar.
It is also the title of a [[http://en.wikipedia.org/wiki/Game_Over_(book) book]]

This trope is too ubiquitous for a proper examples list; we'd be here all century if we tried. Examples go in the [[Quotes/GameOver Quotes section]].
