'''Basic Trope''': The defeat of a VideoGame {{Boss|Battle}} leads to the surrounding area collapsing.
* '''Straight''': [[TheHero Sol]] and [[PlayerParty his friends]] defeat [[WhipItGood Lady Scarlett]] in her own castle. After she falls, the castle begins shaking and collapsing, forcing them to flee for their lives.
* '''Exaggerated''': Every time Sol and his friends defeat a major enemy, the place starts falling apart.
* '''Downplayed''': Sol and his friends defeat the large machine in Lady Scarlett's castle, the room starts to collapse after.
* '''Justified''':
** Scarlett had a powerful spell cast upon her castle so that it would be immediately destroyed upon her death, in order to keep opportunistic self-declared "heroes" from stealing all her wealth and secrets.
** Or, the villain had a huge load of explosives stored in the surrounding area, and told his mooks to set them off if he was killed.
** Alternatively, the villain's lair is only held together by a conscious effort of will, so it goes down when he's killed and can no longer hold the place up.
** Even more alternatively, it could just be held together by him. [[WallMaster Literally.]]
** The mortally-wounded villain, having nothing left to lose, attempts to [[TakingYouWithMe take the heroes with him]] by literally bring the house down on them.
** Or ''more'' alternatively, the boss has damaged a major support during the fight, and said fight ends when they stop and run away.
** The fight between the heroes and the villain has damaged the place so badly that it collapses afterwards.
* '''Inverted''':
** "Haha, [[ThanatosGambit just as I planned]]! MyDeathIsJustTheBeginning! With me dead, you'll never be able to destroy the {{Hellgate}} I was protecting!"
** Alternatively, the battle between Sol with his friends and Lady Scarlett takes place in ruins and defeat of Lady Scarlett causes ruins to reform into a huge castle.
** Another alternative: the boss is going to blow everything up ''unless'' you kill it.
** To defeat Lady Scarlett, you drop her palace on her head.
** The surrounding area collapses when ''you'' die.
* '''Subverted''': Scarlett screams "If I die, I'm TakingYouWithMe!" and collapses -- but nothing happens.
* '''Double Subverted''': However, after the heroes have lingered a few moments, everything starts shaking...
* '''Parodied''': The base starts quaking, only for the boss to open an eye and say "Er, I'm NotQuiteDead yet...", at which everything stabilizes.
* '''Zig Zagged''': "Oh no, the place is collapsing!" "Well, what do you expect, it must have taken some phenomenal magic to keep it standing..." "Never mind, it was just a minor earthquake" "Yes- caused by my [[FisherKingdom sympathetic geomantic powers!]]" "*Gasp* She's NotQuiteDead!" "But I won't allow you to escape - I'm TakingYouWithMe!" *Boom*
* '''Averted''': Lady Scarlett is defeated and the game ends as expected.
* '''Enforced''': The game designers feel there should be just one more little challenge after Lady Scarlett is defeated.
* '''Lampshaded''': "Okay, why is it that the bad guy's lair collapses after we kill him, anyway?"
* '''Invoked''': [[EvilOverlord Emperor Evulz]] set this up as a failsafe.
* '''Exploited''': Sol's mission is to destroy the Evil Lair, and decides to go about doing so by simply killing the boss.
* '''Defied''': "Don't kill him, just knock him out - he might be a LoadBearingBoss!"
* '''Discussed''': "She's dead? Uh oh, ThisIsThePartWhere her lair starts collapsing around our ears and we have to OutrunTheFireball..."
* '''Conversed''': "Another epic battle with the Rat Under The Floorboards last night. I thought about calling an exterminator, but I'm scared this house is like his Final Dungeon and killing him will trigger a localised earthquake..."
* '''Deconstructed''': The collapsing lair kills all of Scarlett's henchmen and dooms her EvilScheme to failure. She is dragged out of the rubble and resuscitated, only to be thrown in jail.
* '''Reconstructed''': She takes some comfort in the fact that her trap still succeeded in [[HeroicSacrifice killing some of the heroes]]. If her henchmen failed to stop the heroes, they deserve whatever they get. Finally, if she can't see her plan through to fruition personally, she doesn't want someone else taking the credit.
* '''Played For Laughs:''' Just before Sol delivers the final blow, the GenreSavvy [[CuteWitch Ichigo]] calls out "STOP!" -- and instructs everyone else to move closer to the exit before giving the okay.
* '''Played For Drama:''' Scarlett kidnapped the heroes' friend Tessa to force them out of hiding; unfortunately, Sol and the others decided to take out Scarlett ''first'' -- meaning that now they have to choose between ensuring they escape in time and searching for Tessa knowing full well that they might not be able to find her before it's too late...

Quick, we have to get back to LoadBearingBoss before this whole place collapses!
