breast bounce. Alternatively, the motion of the breasts may be governed by custom-written software, but this is more time-consuming and therefore rarer than using springs, which are a built-in feature in many game engines. Unnatural breast physics Many video games feature breast movements that appear unnatural or exaggerated, particularly to female observers. This may result from limitations of the "springs" system, which is better suited to animating rigid bodies rather than soft objects like breasts. In some games, however, exaggerated breast physics are intentional. This may be caused by increasing the bounce effect in order to make it noticeable even when a character is standing still and talking, which may result in wildly exaggerated bounces when she actually moves. Ultimately, however, according to game developer Tim Dawson, if a video game features unnatural breast movements, "it's because somebody wanted them to look that way". Not only women's breasts but also male bodies are often intentionally exaggerated or unrealistically portrayed in video games. Breast physics in individual games Games noted for exaggerated breast physics Games noted by video game publications for their exaggerated breast physics include the following: Fatal Fury 2, fighting game (1992) Mortal Kombat, fighting game series (1992–) The King of Fighters, fighting game series (1994–) Soulcalibur, fighting game series (1995–) Dead or Alive, fighting game series (1996–). The bouncing was reduced in Dead or Alive 6, which uses a "natural" body physics engine. Ready 2 Rumble Boxing, sports game (1999) Conker's Bad Fur Day, platformer (2001), in which breasts are used as springboards Lula 3D, adult adventure game (2005), which used motion capture and advertised "Bouncin' Boobs Technology" on its boxart. Resident Evil, action game (2002/2015) Dead or Alive Xtreme Beach Volleyball, sports game (2003) Ninja Gaiden Sigma 2, action game (2009), where the breasts' wobble can be separately controlled by the player Skullgirls, fighting game (2012) Lightning Returns: Final Fantasy XIII, role-playing game (2013) Metal Gear Solid V: The Phantom Pain, action game (2015) Games otherwise noted for their breast physics Policenauts (PlayStation version in 1996): Hideo Kojima “will never forget arguing over the 'breast jiggle issue' with Shuhei Yoshida”. Fortnite Battle Royale (2017) used breast physics in a character model released in September 2018, which attracted controversy. The developer Epic Games later removed it as an "embarrassing and unintended" mistake. Conan Exiles (2017) allows players to customize a female character's breast size or a male character's
