In VideoGames (and probably elsewhere) if you see a wall with cracks on it, you can be certain of two things:

* There is something behind that wall.
* It can be brought down with a well-placed explosive or hit.

See also NoticeThis for unsubtle hints towards locations done for the player's convenience rather than to actually hide stuff. Sister trope of ConspicuouslyLightPatch which typically means the same thing for the player.

!!Examples:

* ''Franchise/TheLegendOfZelda'' has many examples of these. 2D games also have fake wall cracks.
** Although this only helps with fake walls that aren't cracked, tapping them with Link's sword produces a different sound than tapping a solid wall.
** It helps with the cracked ones, too. The aforementioned fake wall cracks might even appear more often than real ones.
* ''ZombiesAteMyNeighbors'', some levels are almost completely made of these.
* ''VideoGame/DukeNukem3D'' has cracked walls you have to break with explosives.
* ''TheSimpsonsGame'' has cracked walls which break when Homer hits them.
* Cracked walls were a critical part of ''VideoGame/StarFoxAdventures''.
* ''{{Okami}}'' has walls with conspicuous (which is to say ''glowing'') cracks in them; once Amaterasu gains the proper ability, these can be blown open with [[StuffBlowingUp explosives]].
** Battle arenas have cracks in them that can be attacked in order to escape from battle. The standard Zelda-style cracks are present, too.
* These are used for SequenceBreaking in the first three {{Avernum}} games. Whether you can break the walls, and hence what you can avoid, depends on the level of the priest spell "Move Mountains."
* The MetroidPrime games used this a lot, especially the first.
* In ''{{Eversion}}'', the more you evert, the more platforms become cracked and can be broken when Zee Tee steps on them.
* In some ''VideoGame/DonkeyKongCountry'' games you can destroy cracked walls with barrels or your rhino buddy.
* In ''VideoGame/BatmanArkhamAsylum'', removable walls -- as well as being explicitly marked in Detective Vision -- are visibly cracked and holed to normal vision.
* The "classic" ''SpyroTheDragon'' games have these.
* In ''VideoGame/FinalFantasyIX'', in the chocobo minigame there are cracks in the mountains that can be dug for treasure. You can't see the chocobo break them because of the graphical limitiations.
* In ''VideoGame/MaxPayne'' there is a cracked wall that will resist your attempts to break it. Until you try to open the door, upon which the whole wall collapses, leaving only the doorframe standing.
* In ''[[VideoGame/BanjoKazooie Banjo-Tooie]]'', cracked wall = [[StuffBlowingUp grenade eggs]]. Cracked ''floors'' also signal that they are able to be broken by a [[ThisIsADrill Bill Drill]].
* [[DefiedTrope Defied]] in the fan remake of ''VideoGame/QuestForGloryII''. Some of the walls of the streets of Shapeir look damaged, but when you click on them the game tells you that while in other games a damaged wall can mean there's something behind it, that isn't the case here.
* ''Wild ARMS 3'' has noticeably cracked walls and Clive has bombs.
* In [[VideoGame/QuakeI the first]] [[VideoGame/QuakeII two]] ''VideoGame/{{Quake}}'' games, several secrets could be discovered this way. Especially in the second game.
* When playing ''VideoGame/Left4Dead'' as zombies, a glowing crack appears on walls that can be broken.
* In the first ''VideoGame/GodOfWar''.
* ''{{Killer7}}'' has cracked walls that can only be destroyed by MASK de Smith's grenade launchers.
* Cruelly, some cracked walls in ''LaMulana'' must be attacked, but others blast you with lightning when you attack them. [[TrialAndErrorGameplay If there's a way to tell which is which, it's not immediately apparent]].
* In ''{{Day of Defeat}}'' the walls that can be demolished by players' explosives are marked this way.
* There's a notable moment in ''DevilMayCry 3'' where you enter a room that doesn't seem to have anything in it... but there's a glowing crack in front of you. Turns out that there's a wall ''almost immediately in front of the door'' that you destroy to carry on.
* If there's a cracked wall in ''{{Dubloon}}'', you can crack it open with your supply of bombs. There's also a more common invisible variation.
* Goes hand in hand with the ''Franchise/{{Castlevania}}'' series. In fact, when the trope doesn't pop up in an installment, fans cry foul.
* ''VideoGame/MetalGearSolid'' tries to justify the trope by saying the [[BossFight boss]] deliberately blocked off walls, and that they are weaker than the ordinary walls.
* In ''{{Pokemon}} Ruby'', ''Sapphire'', and ''Emerald'' there are certain areas in the overworld which can be turned into the entrance to a [[ExactlyWhatItSaysOnTheTin Secret Base]]. One of these is a strange hole in cave walls, which isn't so much a crack as a neatly-defined square ''hole''. In a ''cave wall''.
* ''VideoGame/{{Unreal}}'' has a few and often requires to break them in order to advance. The Na Pali Haven level has even two of those.
* ''{{Heretic}}'''s secret doors were always given away by a telltale light beneath them, or a subtle change in texture.
* ''VideoGame/DeusExHumanRevolution'' has a number of weak walls that your eyes' augments highlight automatically. Once the proper augment is purchased, you can punch through these walls, opening new paths or letting you get in a lethal surprise attack on enemies unfortunate enough to be close to that particular area. You can also knock them down with guns or explosives, but without the aug you'll have to pay very close attention or consult a guide.
* The various games in the ''PaperMario'' series each have their own cracked walls and a bomb-based ally with which to blow them up.
* In ''VideoGame/LegendOfKay'', cracked floors can be broken with the hammer, once Kay gets it.
* ''VideoGame/{{Abuse}}'' also has these at times, which can be broken with any weapon.
* ''VideoGame/SonicHeroes'' has some of these as a minor gimmick in [[BigBoosHaunt Hang Castle]] and [[BigBoosHaunt Mystic]] [[ThatOneLevel Mansion]]. These walls can only be broken with your power character.
** The first ''VideoGame/SonicRiders'' features a variant in [[EternalEngine Egg Factory]]: one part of the course has a sign that's not on its wall straight. Power-type characters, like Knuckles or Storm, can break down that wall to reveal a shortcut.
* The RPG parody comic ''{{Adventurers}}'' mocks this trope in an early strip where Ardam and Karn are trapped in a cave with just a chest, a model airplane, a cracked wall, and several barrels of explosives.
