* ''VideoGame/MetalGearSolid2SonsOfLiberty'' has a mysterious video of the Statue of Liberty with no sound, and some sound files that were never used (like Snake shouting 'La-li-lu-le-lo? La-li-lu-le-lo! LA-LI-LU-LE-LOOO!').
** The Liberty video was going to be part of a news report in the credits following [[spoiler:Arsenal's assault on Manhattan]]. It was removed after 9/11.
** There's also the FAMAS rifle, only available in the Tanker chapter using a cheat device. Snake's FAMAS rifle still appears in the game, but only in one cut-scene which uses FMV footage from one of the pre-release trailers.
** There are several more wigs available for Raiden than the ones that provide actual perks (unlimited breath, ammo, etc), which can be equipped but have no effect whatsoever on gameplay (they don't even change his hair color).
* ''VideoGame/MetalGearSolid3SnakeEater'' has the Bandana from the previous games. You can still access it with a cheat device and even equip it, although it does nothing since this game's infinite ammo item is the Infinity Face Camo.
** The Banana camo and [[VideoGame/ApeEscape Monkey Mask]] are unobtainable in the HD Edition, although data for them still exists in the game, and a hacked save shows that they are fully functional.
* ''VideoGame/MetalGearSolidVThePhantomPain'' had a large number of elements removed or rendered inaccessible prior to release. It has been suggested that this was due to the TroubledProduction[=/=]ExecutiveMeddling that occurred between Creator/{{Konami}} and Creator/HideoKojima.
** The game was originally ''much'' longer than the final product. Datamining uncovered references to ''[[https://facepunch.com/showthread.php?t=1443449&page=10 an entire third chapter]]'', entitled "Peace". In addition to the unused title card, datamining showed that there are at least [[https://www.reddit.com/r/NeverBeGameOver/comments/3p0t0m/mgsv_complete_mission_list_95_missions_27_missing/ ten extra missions]] that were unused, and include "Hard Mode" variants of missions from the final game. There was also an entire unused setpiece, "Kingdom of the Flies (Mission 51)", which would have followed Snake as he [[spoiler:stopped Eli, who had stolen Sahelanthropus and flown to a private island with his army of child soldiers]]. That mission was removed prior to release and can be seen (in a pre-viz/animatic form) on the CE Blu-Ray disc, while references to it appear in the LUA files for the game itself.
** There were plans to include an "[[http://www.ign.com/articles/2014/02/12/metal-gear-solid-5-originally-had-80s-movie-filter 80s Movie Filter]]" that simulated the overblown look of action films from that era, but it was eventually nixed for being a drain on system resources. Luckily, mods exist that perform the same function with the in-game camera filters.
** The Battle Gear was intended to be a usable buddy that could be deployed by the player in combat and driven around by Snake. However, it was cut prior to release for balance reasons, as Kojima felt it was too overpowered. In the end, it was reduced to an appearance in a pair of cutscenes and the ability to be sent on Combat Deployment Missions. References to the unused element can be found in one of the games LUA files and companion app.
** Prior to release, there was going to be a [[OldSaveBonus special mission set at Camp Omega]] for anyone who completed ''Ground Zeroes'' and imported their save. Kojima went on record several times to talk about, claiming that it would include something that had "never been done before in videogames", but no such mission appeared in the final product, even with a save import. A "Black Site" map does appear in ''Metal Gear Online'' (which uses a variant of the Omega map that is greatly changed from its previous incarnation), but the promises about an additional mission never materialized.
** The ''Phantom Pain Companion App'' makes several references to an [[https://www.reddit.com/r/NeverBeGameOver/comments/3onerc/data_from_the_companion_app/ unused mission]] involving Chico at a guardpost in Africa (in the final game, Chico is [[spoiler:mentioned as having died in the chopper crash]]). Likewise, there are references to an unused "Disposal" Mother Base platform - in the final product, nuclear weapons can be disposed of instantly via the iDroid.
** [[https://www.youtube.com/watch?v=ssWgwIl-7ss&feature=youtu.be&t=26m28s Early gameplay presentations]] make reference to several elements at Mother Base that never appeared in the final game, including roaming animals on the Command Platform, and Miller and Ocelot walking alongside the player and giving personnel/status updates to them.
** Snake had [[https://soundcloud.com/gboon/sets/removed-venom-snake-sutherland-dialogue lots of]] [[https://soundcloud.com/gboon/file0355?in=gboon/sets/youre-fired-and-more-cut-snake-dialogue unused dialogue]]. Notably, one set of unused lines is a "staff dismissal" line (much like ''VideoGame/MetalGearSolidPeaceWalker'') and another seems like contextual interactions that could be done with [[spoiler:the Paz hallucination in the Medbay]]. There are also some strange lines where Creator/KieferSutherland recites the names of stations in a Japanese train line, although it's hard to know what context the lines could be used in.[[note]]In previous ''MGS'' games, this was used in a variety of scenarios, usually when an AI was malfunctioning in some way - except the original game, where it's used when Snake arrives in the hallway with people murdered by the Cyborg Ninja.[[/note]]
** There are also unused audiofiles in the game that suggest that Skull Face was originally intended to be a boss, or at least have more interaction than what was seen in the final product. Several lines allude to the fact that he could either be killed or brought back to Mother Base as a prisoner.
** The [=E3=] 2014[=/=]2015 and Tokyo Game Show 2015 "special missions" (which include Snake going to rescue a POW that looks like one of Kojima Productions' playtesters), aren't present in the game itself, although references to it abound in the game files. At least one of these missions (the TGS Africa mission) had elements that never appear in the final product.
** The TGS mission in particular has a large number of scripted elements that don't appear in the retail game. Chief among them is an alternate origin for D.D. -- when Snake first enters the forest in Africa, a gunshot is heard in the distance. After Snake and Quiet dispatch a number of soldiers, they discover a dead wolfdog on the ground and a lone pup whimpering near it. As soon as the pup notices Snake, it begins to follow him, but is distracted by a decoy that is thrown. After the Phantom Cigar is used to pass the time, it's revealed that the pup has followed Snake into the forest, and is finally Fulton-recovered. None of this can be done in the shipped game -- D.D. is only encountered near the start points of missions in Afghanistan and never leaves his spot. It's likely that this whole interaction was specifically scripted for gameplay demos.
** The TGS mission also features a scripted instance where a gunship would rise up in front of Snake near the Lufwa Valley estate while he's escaping after rescuing the POW. No such encounter ever occurs in Lufwa Valley in the retail product.
** The TGS mission also showcased an Active Decoy modeled after "Lisa" from the cancelled ''VideoGame/SilentHills'' - while the radio broadcast from ''P.T.'' does show up in the final game as an EasterEgg, no such variant of the Decoy exists.
** The [[http://www.gamefaqs.com/boards/718564-metal-gear-solid-v-the-phantom-pain/72438179/830671608 physical map]] from the Collector's Edition strategy guide has a master list of delivery points, including several that don't appear on the map or in-game at all. It has been suggested that these corresponded to gameplay locations that were removed prior to release.
** There are many unused models and references to additional camos and buddy equipment. While most of this was eventually integrated into the base game (several costumes from ''VideoGame/MetalGearSolid3SnakeEater'' were eventually released as DLC, while a large number of additional color schemes for uniforms were released as rewards through the FOB mode), there are still some that haven't been released in any way, shape or form. These include a pair of cosmetic uniforms for D.D., which are labeled "Miller" and "Ocelot", and state in their text description that they're the "next best thing" to playing with the actual human allies. It appears that this was intended to be a DLC of some kind, but it was never finished and only references are left in the final product.
** This also occurred in a backwards way with the Gold Bionic Arm (originally an OldSaveBonus for importing data from ''Ground Zeroes''). Its functionality was removed from the game during the 1.05 patch so that it could be sold separately as DLC for consoles, angering people who had originally unlocked it for use in the base game. It was eventually re-added to the game with the release of the ''Complete Experience'' edition.
** One set of PreOrderBonus soldiers (the "Skull" Mother Base Staff) were only offered through [=GameTetsuya=] in Japan, rendering them inaccessible unless a player modded them back into the game. They were finally reintegrated with the game as of the release of the ''Complete Experience''.
** The Fulton Launcher (a reward from the FOB mode) is a subversion of this, as it existed (unused) on-disc for more than ''two years'' before finally being added in the 1.10 update. Some players were disappointed when they discovered that the version officially released was the exact same as the initial on-disc version, with no changes or tweaks to its model or firepower.

* The final level of ''VideoGame/HitmanBloodMoney'' has a room that cannot be accessed without carefully placed teleportation skills using the Command Window. The room is the crematorium where [[spoiler: 47 was to be killed.:]], which, most likely would have been implemented, had the AlternateEnding not been chosen instead.

** There were plans to include an "[[http://www.ign.com/articles/2014/02/12/metal-gear-solid-5-originally-had-80s-movie-filter 80s Movie Filter]]" that simulated the overblown look of action films from that era, but it was eventually for being a drain on system resources.

*** The train station line is actually a RunningGag in the series, usually said in circumstances related to malfunctioning mechanics (except in ''VideoGame/MetalGearSolid4GunsOfThePatriots'', where Sunny sings the names aloud while making eggs, and ''Snake Eater'', where it does not appear at all).

* ''MetalGearSolid2'' has a mysterious video of the Statue of Liberty with no sound, and some sound files that were never used (like Snake shouting 'La-li-lu-le-lo? La-li-lu-le-lo! LA-LI-LU-LE-LOOO!').

The room is the crematorium where [[spoiler: 47 was to be killed.:]], which, most likely would have been implemented, had the AlternateEnding not been chosen instead.

* Aside from some data for the cancelled ''{{Thief}} II Gold'' bonus levels, the ''entire multiplayer feature'' in ''{{Thief}} II'' definitely counts. Cut from the game due to time constraints, multiplayer was later modded back in using netcode in the game's files, and maintains a small community of players.
