[[caption-width-right:292: Watch your step.]]

A FightingGame trope, where the fight ''isn't'' always limited to the plane that it starts on. This can open a lot more variation for stage effects, transitions, and action that ends in a completely different place from where it starts. This makes the matches more dynamic than the static counterpart, FixedFloorFighting.

Because of the somewhat more random nature of the fights, battle tactics can be changed. Some combos may be cut short due to the environment not allowing them, a RingOut or environmental damage may be more possible, etc. In this genre, a LauncherMove may simply knock an opponent through a predictable path, or open a new path through the game's environment.

Contrast FixedFloorFighting and PlatformFighter. Outside of the FightingGame genre, see ChaseFight.

!!Examples:

* ''VideoGame/XMenNextDimension'' has levels where you can knock an opponent from one section down to another, dealing additional damage to them. For some levels, there are even multiple paths to make them fall.
* ''VideoGame/DeadOrAlive'' picked this up in the second game onward, instead of the ''VirtuaFighter''-style {{Ring Out}}s used in the first.
* ''VideoGame/DragonBallZBudokai'': In addition to knocking opponents to new areas, characters can also fly and introduce an entire new dimension to fights.
* ''VideoGame/MortalKombatVsDCUniverse'' has this. In most stages, you can go into "Vertical Kombat" by knocking an opponent off a ledge or through the floor, and some of them also allows you to smash them through walls and buildings into new areas. In both cases, you are able to keep hitting your opponent during the sequence, using a button-mashing minigame. In this series, this goes at least as far back as ''VideoGame/MortalKombat3'', which had stages in which uppercutting the opponent would send them to another stage directly linked to the previous one. In ''Deception'' and ''Armageddon'', many stages had more than one area working in the same principle of the aforementioned Vertical Kombat system, except without the Kombat.
* ''MadWorld'' has fights that are as simple as a plane (or rather, the ceiling of a [[ShoutOut familiar]] [[Franchise/StarTrek ship]]), or as complex as ''the entire castle of the last level you just played'' (i.e. The Courtyard, where you fight the Shamans).
* ''VideoGame/TatsunokoVsCapcom'': Uncharted Region of China has a breakaway floor, and Galactor's base has a path that can be adjusted. Both of these are affected by attacks that damage the ground.
* ''VideoGame/SuperSmashBros'': Stages in this game vary from as constant as Final Destination to as chaotic as Big Blue (pictured above). In this stage you actually fight on top of [[VideoGame/{{F-Zero}} cars as they race around a track.]] If you fall off of one and onto the asphalt, you get whisked off the side of the stage as the camera leaves you behind, resulting in a near-instant KO unless you can ''very'' quickly jump off and return to the stage.
* ''[[{{Tekken}} Tekken 6]]'' had certain stages where the floor would collapse, and you can smash opponents through some walls as well. ''Tekken Tag Tournament 2'' adds the ability to knock enemies off some balconies, blowing them through the railings and onto the floor below.
* ''[[VideoGame/SoulSeries Soul Calibur V]]'' has, on several stages, the fight moving to a lower floor if one player suffers a RingOut. Before the next round starts, the winner will land on his or her feet and the knocked-out player will struggle to stand up straight.
* ''VideoGame/StreetFighterXTekken'' has a twist on this in that you switch planes/areas in between rounds.
* All stages in ''VideoGame/PlayStationAllStarsBattleRoyale''. Special mention goes to Dreamscape from LittleBigPlanet, which starts completely flat but builds itself up in classic LBP-fashion, eventually becoming the most platform-heavy arena in the game.
* In ''VideoGame/InjusticeGodsAmongUs'', characters can knock their opponents into new sections of the arena, with transitions that include being knocked through several buildings, hit by a train, getting being beaten up by Batman's RoguesGallery, or ''knocked into the exposed vacuum of space, bouncing off a satellite, and then get smashed into by an out of control shuttlecraft'' along the way.
