An invisible wall is a boundary in a video game that limits where a player character can go in a certain area, but does not appear as a physical obstacle.[1] The term can also refer to an obstacle that in reality could easily be bypassed, but don't allow the character to jump over them within the game, such as a mid-sized rock or short fence.[2] In 2D games, the edge of the screen itself can form an invisible wall, since a player character may be prevented from traveling off the edge of the screen.[citation needed]

In 3D games, invisible walls are used similarly to prevent a player leaving the gameplay area, however: visible boundaries such as stone walls or fences are generally preferred. Invisible walls are cited to be level design bugs, and might be "left-over geometry" from an earlier version of the level or an object's improperly aligned "collision box".[3][4] Nevertheless, designers might add invisible walls on cliffs to keep characters from falling off[5] or use them as final borders of large open worlds, to make the world appear even larger than it actually is.[3]

Reception[edit]

Invisible walls can create discrepancies between a game's systemic logic and its fictional logic, as a game's rules dictate that one cannot continue past the wall, while the fictional setting cannot explain why this is. This breaks the supposed internal reality of the game.[6] Invisible walls are harshly criticized for breaking player immersion,[2][7] but such barriers are necessary to "preserve the entertainment value of the game by keeping the game scenic ... improving overall immersion."[8][9]

More novel ways of obstructing a player character from leaving an area, such as placing invinsible enemies between the player character and the invisible walls, are considered an optimal tactic to keep the game scenic. This way, a player may feel reward for their attempts and find that the game's designer has considered the player's behavior.[10]

Noclip mode[edit]

Alternatively, computer glitches or use of computer game cheats can result in both clearly physical walls, as well as invisible walls, becoming penetrable. If a player character passes through a wall, they may enter an area of the game not intended for their use. This might be an area containing unused portions of a level, or an area containing nothing at all. Visible and invisible walls exist to keep players out of such areas.[10][11]
