* Applies to [=MGS=]2 through to 4 (and Twin Snakes as well): You can press a button during cutscenes to zoom the camera in. If you do this when the camera's point-of-view is looking through a set of binoculars or a handheld camera, the various numbers and bars change as well.

* With the right upgrades, you can use fulton recovery on objects like a container. If you're standing on it, you will get picked up back to your base immediately as well. You can also use it to reach the upper floors of buildings.

* Using the Stun Arm while listening to tapes causes audible static feedback.

* One of the many unlockable tapes in game contains audio of a certain somebody in a porta-john having...[[ToiletHumor bowel issues.]] One of the [=iDroid=] upgrades you can get allows you to play tapes aloud to get people's attention. Whenever you end up with a suspicious enemy coming your way, if you hide in a toilet and play this tape, the guard will respectfully walk away and leave you be.

* If the player shoots the soldiers in the butt or in the crotch, it will instantly knock them out.

* You can make the Colonel and Rose upset if you take a picture of a hostage's underwear.

* When you are taking Emma across water, Raiden tells her to listen to his heartbeat so that she'll stay calm and doesn't panic. Take some Diazepam, and Emma's oxygen lowers at a slower pace.

* There's one specific platform near one of the locations where you need to take one of Ray's pictures where you can spot Ocelot, but he's there only if you don't have any weapons equiped and if you equip one, he disappears immediately.

* Master Miller is unavailable during the Hind helicopter fight. [[spoiler: Because he's really Liquid, who is busy fighting you in said helicopter.]]
** Although, before the Hind D battle starts, Miller mentions he'll try to find more information on [[TheMole Naomi]].

* Similar to ''VideoGame/MetalGearSolid3SnakeEater'', spinning Snake around on the model viewer/[=OctoCamo=] selection screen will result in Snake vomiting.

* Various Codec calls and conversations to characters will also be slightly different depending on the player's prior actions. In Rassvet, for example, Snake's response to Zero in regards to the guard level depends on how the player handles sneaking past the guards. If the player evades detection completely, Snake will respond with "No one spotted me." Likewise, if he gets an alert or kills the soldiers, he'll respond with "I managed to get past them." and "I had to kill them... there was no other way. But no one will know we were involved." Also, call Sigint when the flame troops arrive at Krasnogorje. If the player got a bit too triggerhappy with soldiers, Sigint will state that the reason why they are after Snake is because he killed many of their comrades. Likewise, if the player restrained him/herself from killing anyone (except for maybe the Cobra Unit), Sigint will respond with Volgin sending them to torch him as revenge for disposing of The Pain, The Fear, and The End. In addition, Volgin's analysis on his body check on Snake before torturing him will be different depending on how frequent the player seriously injured him/herself gameplay-wise. If the player had very little, if any, (serious) injuries prior to being tortured, Volgin will state "What a beautiful body you have, like a newborn baby. But not for long..." If the player received a moderate amount of injuries, Volgin will state "Hmm... you've certainly seen your share of battles. Consider yourself lucky. I am about to show you what hell is really like." Lastly, if the player received a lot of injuries, Volgin will say "You're a tough one my friend, a lesser man would be dead by now."

* Shoot or stab Ocelot anywhere on the body without killing him. He will possess a bandage in that spot in all future appearances.

* During the short period of time you have EVA in your party, so to speak, you can check her medical history. Turns out she has breast implants, she has eaten a Tsuchinoko, [[{{Squick}} and]] [[http://en.wikipedia.org/wiki/Proctitis Proctitis]]. Is it possible for Kojima to troll his own series?

* If you look to the far left using the analogue stick [[spoiler:when Solidus is choking Raiden,]] the oxygen gauge will deplete more slowly. This is because [[ShownTheirWork you move your neck into a position where the choking is less effective.]]

* If you look to the far left using the analogue stick [[spoiler:when Solidus is choking Raiden,]] the oxygen gauge will deplete slower. This is because [[ShownTheirWork you move your neck into a position where the choking is less effective.]]

* When the Commandant is giving his speech you can screw around with the projectors to make them switch between screens and show pictures of sexy women, which the soldiers turn towards. If you do it too many times in a row, the soldiers figure out something's wrong, turn towards you and catch you. [[ViolationOfCommonSense Run in front of the projectors]] and they'll spot you, too. Even with the unlockable stealth camo on (Since its still disturbing the light ray coming from the projector.)

* Speaking of the uniform, you'll notice it's still in your inventory despite being useless now that it's lost the balaclava. Turns out it's not ''completely'' useless: if you wear the uniform in an area where you'll leave footprints, the guards will ignore them rather than follow because they match their own boots.

* Likewise, destroying the ammunition storages will make the guards carry only one clip of ammo for their rifles. If they empty that clip after spotting you, they'll drop their rifles and chase you with their combat knives.

* Psycho Mantis can read ''the player's'' mind by reading memory card data, providing a detailed analysis of the player's proficiency at the game (how good they are at stealth and combat, and how frequently they've saved their game), and suggesting that the player enjoys certain games like, say, ''VideoGame/{{Suikoden}}'' or ''[[VideoGame/CastlevaniaSymphonyOfTheNight Castlevania]]'', [[WebAnimation/AwesomeSeries for instance,]] or ''VideoGame/SuperMarioSunshine'' and ''[[VideoGame/SuperSmashBros Super Smash Bros. Melee]]'' in the GameCube remake. Even better, in the Japanese version, having save data from both VisualNovel/{{Snatcher}} and VisualNovel/{{Policenauts}} unlocks a special message from HideoKojima.

* Quiet's boss fight can be finished incredibly quickly, as all the player has to do (Rather than either engage in a sniper duel with her or sneak around and use the Silent Pistol to tranq her) is mark her location before calling in a supply drop on her head, which knocks half her stamina out. Do it twice, and the whole fight can be resolved in just a few minutes.

* If you destroy the comms equipment in the Eastern Communications Post in Free Roam Mode and then attempt the C2W mode from a chopper, [[https://www.youtube.com/watch?v=1Uir3iO3sSc Ocelot will note that the comms equipment has already been destroyed]] [[{{Anticlimax}} and the mission will end instantly]].

[[AC:Ground Zeroes]]

* Destroying food storages in an area will cause your enemies to suffer from hunger when you return later, affecting their performance. They get so hungry, in fact, that you can [[VideoGameCrueltyPotential throw them meat from a poison dart frog, and they will eat it gleefully... then keel over dead]].
