''[=FlatOut=]'' is a franchise of {{Racing Game}}s originally created by Finnish developer Creator/BugbearEntertainment (who also made ''VideoGame/RallyTrophy''). The ''[=FlatOut=]'' series is notable for its [[WreakingHavok physics engine]], which it uses to simulate lots and lots of crashes, wrecks, [[RagdollPhysics personal injury]], crashes, [[DieChairDie complex object interactions]], vehicle damage, and [[SoGoodWeMentionedItTwice crashes]]. There is a lot of crashing.

!!!Games in the series include:
* ''[=FlatOut=]'' -- UsefulNotes/{{Xbox}}, UsefulNotes/PlayStation2, PC
* ''[=FlatOut=] 2'' -- UsefulNotes/{{Xbox}}, UsefulNotes/PlayStation2, PC

!! ''[=FlatOut=]'' contains examples of:

* HundredPercentCompletion: The game helpfully displays your percent-completion rate.
* TheComputerIsACheatingBastard: Ultimate Carnage features a catch up boost system that makes certain the AI is always right on your tail, to increase the challenge for pro racers. This is made readily apparent in some tracks where the pack will actually teleport ALL the cars up behind you if you're performing too well, too fast. This is rare, however, and there are even times where you can lap some of the slower characters. But you can still imagine the horror when you suddenly see eleven cars appear from nowhere on the minimap behind you, and uncluster as they come after you.
* DieChairDie: You can interact with a wide variety of objects on the courses, but there's nothing to do with them except smash into them.
* DifficultButAwesome: The Flatmobile of ''[=FlatOut=] 2'' is so comically fast that any typical player simply cannot control it. However, said acceleration is equally reciprocated in its brakes, and at sane speeds it can out-handle any vehicle in the game. In the hands of a truly skilled gamer, no other vehicle can possibly compete, even in the infamous destruction derbies.
* InVehicleInvulnerability: The [[RagdollPhysics ragdoll]] driver can survive any crash unless he is thrown from the vehicle.
* NitroBoost: You have a Nitro meter that fills up as you crash into stuff and can be used for a speed boost.
* RagdollPhysics: {{Exaggerated}}. Every time you crash, you're treated to [[MundaneMadeAwesome a slow-mo cutscene of your driver getting thrown from the car]]. And on top of that, there are a whole selection of minigames that involve ''intentionally'' ejecting the driver to see how far or how accurately you can toss him.
* RecycledTitle: ''[=FlatOut=]'' for the Wii.
* RewardingVandalism: You get Nitro for crashing into stuff. Also, see YouBreakItYouProfit.
* SlippySlideyIceWorld: The snow tracks in the first game, with their reduced traction, fit the standard racing game variant of the trope.
* SpiritualSuccessor: ''VideoGame/{{Wreckfest}}'', which first debuted to the public by its working title, ''Next Car Game''.
** The series itself is one to the Destruction Derby series on the PS1 and N64.
* UpdatedRerelease: ''[=FlatOut=]: Ultimate Carnage'' and ''[=FlatOut=]: Head On'' are ports of ''[=FlatOut=] 2'' with extra cars, new characters and a different soundtrack.
* VideoGameCrueltyPotential: The minigames, which center around intentionally tossing the ragdoll driver out of the vehicle.
* WreakingHavok: The game makes extensive use of its physics engine to render realistic vehicle damage and crashes and so on. See also RagdollPhysics.
* YouBreakItYouProfit: At the end of the race, you're given money based on how much damage you did to the track. Doing damage during the race also restores your supply of nitro - the more damage you do, the more nitro you receive.
