Metal Gear Solid Secrets: 50 Amazing Things You Need To Know

Dave Cook


Metal Gear Solid secrets are a massive part of what makes Hideo Kojima's series so special. To celebrate the release of Metal Gear Solid HD Collection, we check out 50 of the best.

Published on Jan 31, 2012

Metal Gear Solid HD Collection is out this Friday, and to celebrate we thought we'd take a look back across the series - all the way back to Metal Gear on NES in fact - to find 50 of the greatest secrets buried in each of the games.

After all, Metal Gear games are famed for their easter eggs and odd things to discover along the way, and if anything, these secret moments underline just how creative Hideo Kojima and his team can be. 

So read on and prepare to be shocked, amazed, disgusted, intrigued and perhaps even a little bit turned on - yes you read that right. Don't say we haven't warned you.


50. Liquid Ocelot kisses Old Snake

Metal Gear Solid 4: Guns of the Patriots

At the end of Metal Gear Solid 4, Old Snake and Liquid Ocelot fight to the death while some lame music plays. Every so often, Ocelot will get Snake in a headlock. If you ignore the QTE prompts for a while, Ocelot will give Snake a massive kiss on the cheek. 


49. Naomi’s massage

Metal Gear Solid

After being brutally tortured by Ocelot, Snake is locked in a jail cell. During a codec call with Naomi Hunter, the player is asked to put their PSone controller up against their forearm to receive a healing massage, which simply involves the controller vibrating violently.


48. Slipping In Bird Poo

Metal Gear Solid 2: Sons of Liberty

After Raiden infiltrates the Big Shell facility, he ascends to the roof to get a better look at his surroundings. Run too carelessly on the roof and Raiden will slip in seagull droppings, making him fall flat on his back. The big fool.


47. Snake controlling Metal Gear MK-2 with a PS3 controller

Metal Gear Solid 4: Guns of the Patriots

Whenever Snake is controlling his robot buddy Metal Gear MK-2, look closely at his hands. You’ll see that Snake is controlling the device using a PS3 controller.


46. Mario’s 1-up jingle  

Metal Gear Solid: The Twin Snakes

Once Snake gets to Otacon’s office for the first time, you can see figurines of Mario and Yoshi on a desk. If you shoot the Mario figure, Snake’s health will be replenished, accompanied by the Super Mario Bros. 1-up jingle. 


45. Dressing up as Raikov

Metal Gear Solid 3: Snake Eater

In Metal Gear Solid 3, Naked Snake knocks out Raikov – a parody of Metal Gear Solid 2’s Raiden - and wears his uniform. Snake will then hide the unconscious Raikov in a locker. If you look inside the locker you will find a promotional poster for Metal Gear Solid 2 featuring Raiden.


44. Sunny plays Penguin Adventure

Metal Gear Solid 4: Guns of the Patriots

During Otacon’s briefing at the start of act two, keep an eye on what Sunny is doing. She starts rummaging around in a cardboard box and will eventually produce a Sony PSP. She will then sit down and start playing level three of the 1986 MSX game Penguin Adventure, which was Hideo Kojima’s first project as a game developer.


43. “Fission Mailed”

Metal Gear Solid 2: Sons of Liberty

During a stand of between Raiden, Pliskin and waves of enemies, the game suddenly goes picture in picture and the message ‘Fission Mailed’ appears on the screen, along with a ton of gibberish. You can keep on fighting while this happens.


42. Otacon’s Policenaut’s Poster

Metal Gear Solid

If you look around Otacon’s office in the first Metal Gear Solid, you will notice a poster for the 1994 game Policenauts, another iconic Hideo Kojima game. Oddly enough, Meryl Silverburgh is also a character in Policenauts.


41. Snake has a recurring death dream

Metal Gear Solid 4: Guns of the Patriots

If you get killed in Metal Gear Solid 4, retry and instantly call Rosemary on your codec. Snake will explain that he is constantly having dreams about dying, which is met with a different psychological analysis from Rosemary each time you call her.


40. Kissing Posters Of Models

Metal Gear Solid 2: Sons of Liberty

If you hide inside a locker that has a poster on the back of the door, switch to first-person view and zoom in on the image. Once you zoom in as far as you can go Raiden will kiss the poster loudly.


39. Ivan Raidenovich Raikov

Metal Gear Solid 3: Snake Eater

Second in command to Volgin, RaIkov looks suspiciously like Metal Gear Solid 2’s Raiden, not to mention his middle name being a dead giveaway. Throughout the game, Raikov is the focus of parody as a result of fan backlash to Raiden, with many characters poking fun at him along the way. Poor sod.


38. Catching Meryl In Her Underwear

Metal Gear Solid

Near the start of the game, Snake must climb through a series of vents shafts to locate the DARPA chief’s prison cell. Snake can spy on Meryl doing sit ups in the cell next door. If you leave and enter the vent shaft four times, you will find Meryl doing sit ups in her underwear.


37. Otacon asks you to swap discs

Metal Gear Solid 4: Guns of the Patriots

Just before Snake ventures into the blast furnace area, Otacon will call Snake on his codec and ask him to insert disc 2 – which is similar to the disc swap sequence from the original Metal Gear Solid. Otacon will then realise that Snake doesn’t have to swap discs as the game is on a Blu-Ray instead. They’re clearly PS3 fanboys.


36. Doing Pull-Ups With Raiden

Metal Gear Solid 2: Sons of Liberty

Raiden can hang off ledges for a short time in Metal Gear Solid 2, but he will fall once the grip meter depletes. To level up Raiden’s grip, you can hang off a ledge and press both R1/R2 to perform a pull-up. Do 100 pull-ups to increase Raiden’s grip level by one, and to get an over-excited, congratulatory codec message from Campbell and Rose.


35. Crop Circles

Metal Gear Solid 4: Guns of the Patriots

After defeating Laughing Octopus in act two, you will venture out to track down Naomi. If you head left following the river, you will come across a crop circle. Campbell will then contact you by coded to discuss the time he was abducted by aliens with Snake. The abduction is also mentioned in Metal Gear Solid 2. Weird.


34. Developer Ghosts

Metal Gear Solid

There are 42 ghosts hidden throughout Metal Gear Solid, that are actually images of the development team at Konami. You can only view them by looking through Snake’s camera. Hideo Kojima’s ghost can be found imprinted on the Policenauts poster in Otacon’s office.


33. Vulcan Raven Figurine

Metal Gear Solid 2: Sons of Liberty

During the opening tanker act, Snake makes his way to the engine room. After turning a corner, he gets startled by the silhouette of Metal Gear Solid boss Vulcan Raven on the wall. On closer inspection, the shadow is being cast by a small Vulcan Raven action figure in front of a toppled lamp. 


32. Eva’s medical records

Metal Gear Solid 3: Snake Eater

While accompanying Eva to the WIG aircraft, make Snake stand close to her then open the cure menu. Select Eva then press R1 to see her skeleton. You can then press R2 to see a list of her recently eaten meals and medical records, which include ‘breast enhancement’. Oh dear. 


31. Fighting the Hind D in mono

Metal Gear Solid  

If you call Campbell while fighting the Hind D gunship, he will advise Snake to listen out for the sound of the chopper’s rotor blades to find out where it is. But if the game sound is set to mono, rather than stereo, Campbell will become confused, and reassures Snake that he can still win without stereo sound.


30. “Gabe and Sam”

Metal Gear Solid 3: Snake Eater

As a bonus extra, Metal Gear Solid 3 includes the minigame Snake Vs. Monkey, which is a fun crossover between Metal Gear Solid and Ape Escape. During the opening codec dialogue between Snake and Campbell, Snake complains about the nature of the mission and asks if “Gabe or Sam” could do it instead. This is a reference to protagonists of similar stealth games – Syphon Filter’s Gabe Logan and Splinter Cell’s Sam Fisher. 


29. Using Porno Mags To Distract Guards

Metal Gear Solid 2: Sons of Liberty

Throughout Metal Gear Solid 2, Raiden can throw a dirty magazine on the floor that will grab the attention of any passing guards, leaving them open for the kill, or a cheeky tranquiliser round or two. Snake can also do this in Metal Gear Solid 4.


28. The Laughing Kojima Portrait

Metal Gear Solid: The Twin Snakes

In the Gamecube version of Metal Gear Solid, the Psycho Mantis boss battle room features a portrait of Hideo Kojima. If you move the controller after Mantis laugh during the pre-battle cutscene, the image changes to Kojima laughing like a madman, together with a shrill laughing sound.


27. The early End

Metal Gear Solid 3: Snake Eater

Elderly master sniper The End can be killed before his boss fight, but only if you’re quick and clever enough. You can snipe The End with an SVD rifle when he first appears after the Ponizovje Warehouse, completely removing the boss battle from the game. Snake also gets upset about killing The End while he was in his wheelchair.


26. Handprint camo

Metal Gear Solid 4: Guns of the Patriots

While exploring the mountain trail area, Raiden will contact Snake and ask him to look around for tracks on the ground. Equip the Solid Eye’s night vision function and look at the path to see a series of handprints. Follow the marking to a concrete slab that features handprints of the developers. You can then lie on the slab to collect the handprint camo pattern. 


25. Faking your death in the jail cell using ketchup

Metal Gear Solid

After being tortured by Ocelot, Snake finds himself locked in a jail cell. You can end Snake’s imprisonment early by using a bottle of ketchup snuck in by Otacon. Snake spills the ketchup over the floor and lies on top of the puddle, making it look like he is fatally injured and bleeding. When the guard enters the room to help, Snake simply stands up, beats the crap out of him then escapes. 


24. Snake rolling in an oil drum

Metal Gear Solid 4: Guns of the Patriots

Similar to the cardboard box item, Snake can hide under oil drums as cover. You can even flip it on to its side, climb into it and then roll down hills to bowl over unsuspecting guards. However, doing this causes a dizzy Snake to throw up all over the ground.


23. Using Sniper Wolf’s hankerchief to avoid the dogs

Metal Gear Solid

After defeating Sniper Wolf, Snake can pick up her scarf – referred to in the game as her hankerchief – and equip it. While Snake has the scarf equipped, attack dogs and wolves will not attack Snake due to Sniper Wolf’s scent. 


22. Psycho Mantis goes nuts over SIXAXIS

Metal Gear Solid 4: Guns of the Patriots

Following Snake’s battle with Screaming Mantis, the ghost of Psycho Mantis will appear and taunt Snake, boasting of his telekinetic powers. He tries to read your memory card in a similar fashion to the original Metal Gear Solid. Mantis gets enraged when realises that your PS3 doesn't have a memory card. 

Mantis then tries to move your SIXAXIS controller with the power of his mind – again, similarly to the original Metal Gear Solid – but then freaks out when he realises that it doesn't have vibration. However, if you’re using a DualShock 3 controller, Mantis will make your controller vibrate and cheer. 


21. Raiden gets scolded for looking at a girl’s pants. (Watch at 2:23)

Metal Gear Solid 2: Sons of Liberty  

While searching for Ames among the group of hostages, you can point Raiden’s directional microphone at a hostage named Jennifer. By doing so, she will become alarmed and open her legs to reveal her underwear. Quickly call Campbell to receive a dressing down for your naughty actions.


20. Beauty And The Beast photo shoot

Metal Gear Solid 4: Guns of the Patriots

After defeating a member of the Beauty and the Beast unit, they will remove their power armour and walk around in their cat suit. After a few minutes, both Snake and the Beauty will be teleported to a white room. If you equip Snake’s digital camera the Beauty will strike model poses for you as you take photos. 


19. Big Boss asks you to turn off the console

Metal Gear

The game that started it all, Metal Gear delivers a big plot twist and an excellent bit of fourth wall-breaking humour as Snake realises that his handler Big Boss is actually the villain.

As Snake starts to piece the clues together, Big Boss gets desperate and contacts Snake over codec, commanding him to abort the mission by asking the player to turn off their NES console. 


18. Making Naked Snake throw up

Metal Gear Solid 3: Snake Eater

If you want to make life hard for Snake, simply open the survival viewer, make Snake eat a lot of stuff and hold down R1 to make him spin around. After about four or five spins, return to the game and Snake will get dizzy then throw up all over the ground, lovely.


17. Everyone flirts with Snake

Metal Gear Solid: Peace Walker

After completing Peace Walker, Big Boss can wear the tuxedo during subsequent new games. Whenever the Boss calls up characters on his codec, they will occasionally flirt with him and make compliments on how sharp he looks. Others will condemn Big Boss for wearing something so ridiculous on the battlefield.


16. Snake Vs Monkey

Metal Gear Solid 3: Snake Eater

This crossover between Metal Gear Solid 3 and Ape Escape sees Snake chasing and capturing monkeys in the jungle. It’s a zany extra on the Metal Gear Solid 3 disc, featuring a ton of mad dialogue from Campbell and levels that mix movie titles with the word ‘ape’, such as ‘Night of the Living Apes.’


15. David Hayter interview in MGS 4

Metal Gear Solid 4: Guns of the Patriots  

There is an interview with David Hayter - the voice of Solid Snake – hidden within the opening cut scene of Metal Gear Solid 4. As you start a new game, you will see a string of television shows and adverts playing. You can flick through other TV shows by pressing various buttons, including a hidden video interview of Hayter wearing Snake’s Solid Eye device. 


14. Raiden in the toilet (Watch at 3:54)

Metal Gear Solid 2: Sons of Liberty  

Early on in Metal Gear Solid 2, Raiden is instructed to explore the Big Shell facility for a bomb disposal expert. Along the way he encounters both male and female restrooms. If you enter the female restroom and call Campbell or Rose, you will get repeatedly scolded for being a pervert. Better still, if you call Campbell while in a restroom cubicle, Campbell will ask Rose to give Raiden some privacy by leaving the conversation.


13. Making Snake pose with a naked statue

Metal Gear Solid 4: Guns of the Patriots

During the first act, Snake encounters street teeming with PMC soldiers. At the top of street is a fountain decorated with a statue of a naked man. It is possible to have Snake pose next to the statue using his active camo suit, resting his hand on the statue’s penis. Do this multiple times and the penis will break off, alerting all guards in the area. 


12. Leap of Faith

Metal Gear Solid: Peace Walker

There is a neat little crossover with the Assassin’s Creed series hidden in Metal Gear Solid: Peace Walker. By climbing up on a rooftop, it is possible to perform the Leap of Faith jump from Assassin’s Creed straight into a box of hay. The jump comes complete with the familiar eagle sound effect, and after landing in the hay, Master Miller will call Big Boss on his codec to give him some history on the technique. 


11. Snake’s iPod

Metal Gear Solid 4: Guns of the Patriots

To reduce his stress level, Snake can listen to his iPod. It comes preloaded with a few songs and Metal gear Solid podcasts, but you can also unlock music from across the entire series – right the way back to the NES original – by meeting certain requirements. There are even songs from other Kojima games Boktai, Policenauts, Snatcher, Lunar Knights and Zone of the Enders in there too.


10. Johnny has a toilet malfunction

Metal Gear Solid 2: Sons of Liberty

The recurring character Johnny Sasaki constantly has bowel problems and bouts of diarrhoea throughout the Metal Gear Solid series. In Metal Gear Solid 2, Raiden is asked to dress up as an enemy soldier and use his directional microphone to locate Ames. 

But by pointing it at a nearby bathroom stall instead, Raiden can listen in on Johnny having bowel problems on the toilet, before realising he’s run out of toilet paper – oops. 


9. “HIDEO” (Watch at 4:57)

Metal Gear Solid

This classic moment is utterly confusing the first time you experience it. While fighting Psycho Mantis, he will occasionally perform a telekinetic trick that is supposed to look like he is tampering with your television. 

The screen will quickly turn black, and produce a shrill ringing sound, as well as plastering ‘HIDEO’ over the top right corner of your screen. After a few seconds the game will return back to normal.


8. Miller goes nuts for boxer shorts

Metal Gear Solid: Peace Walker

Dressing up Big Boss in boxer shorts results in some hilarious codec conversations between the player and Kaz Miller. At first Miller will seem exasperated with Snake’s outfit choice, but will grow increasingly pressured to follow the Boss’s style. Eventually Miller will crack and will rant at Boss over codec, stating that he has stripped off completely in an attempt to fit in. 


7. Messing with the projectors

Metal Gear Solid 2: Sons of Liberty

During the tanker chapter, Otacon will ask Snake to take photos of Metal Gear Ray, but first he has to sneak past many soldiers looking at projector screens. It is possible to tamper with the projector device in the second hold.

If you keep on messing about with the image, a cut scene will play that shows Snake projecting images of female models on all screens, causing the soldiers to spot Snake, and resulting in a game over. 


6. Snake’s Nightmare

Metal Gear Solid 3: Snake Eater

Hidden within Metal Gear Solid 3 is a secret minigame called Guy Savage. Immediately after Snake is tortured by Volgin and placed in the Groznyj Grad jail, save the game and reload your file. 

This will trigger a codec scene between Snake and Para-Medic that involves her talking about horror movies. Snake will fall asleep during the conversation, triggering the Guy Savage game.

It stars a character that battles zombies with two hooked blades using a variety of hack and slash attacks. The fight ends when the time runs out and Snake snaps out of his dream. 


5. Hideo Kojima in Peace Walker

Metal Gear Solid: Peace Walker

It is possible to recruit Metal Gear creator Hideo Kojima to your squad in Metal Gear Solid: Peace Walker. During the mission ‘Infiltrate the Crater Base’ you will eventually reach a cutscene that sees Big Boss attempting to find nukes that are stashed inside trucks. 

Find the truck with the license plate 63824, Hideo Kojima will be hiding inside. After Big Boss says “Mr. Kojima?”, he will be extracted to Mother Base for use in your squad later.


4. Making The End die of old age

Metal Gear Solid 3: Snake Eater

Perhaps one of the most impressive boss battle strategies ever implemented in a game, it is entirely possible to make elderly sniper The End die of old age, rather than fighting him head on. 

Once the boss battle begins, simply save your game and wait over a week before reloading the game – or simply skip your console’s internal clock forward a week. When you return to the game, The End will have passed away due to old age. However, Snake expresses regret for winning the battle this way.


3. Dreaming of Shadow Moses

Metal Gear Solid 4: Guns of the Patriots

During act four of Metal Gear Solid 4, Snake returns to the Shadow Moses facility to obtain the railgun attached to Metal Gear Rex. As Otacon flies Snake to the facility, he falls sleep and dreams of his mission at Shadow Moses during the first Metal Gear Solid. 

During the dream sequence you have to actually play the opening minutes of the game, as Snake infiltrates the facility be running across the Hind D helipad. As Snake wakes up from his dream, his face resembles his old PSone character for a split second. It’s a classic bit of nostalgic fan service. 


2. Ocelot time paradox

Metal Gear Solid 3: Snake Eater

This is a very clever piece of lore bending from Kojima, in which Snake knocks out a young Ocelot. After knocking him out, you can actually kill Ocelot, which triggers a time paradox game over. The paradox is a result of Ocelot being instrumental to subsequent games in the timeline.


1. Psycho Mantis reads your mind

Metal Gear Solid

The moment that made the top spot in our 50 Greatest Game Moments occurs just before Snake fights with telekentic genius Psycho Mantis. Showing off his powers, Mantis attempts to read Snake’s mind by reading your PSone memory card, commenting on any Konami save games you have.

For example, if you have a save from Castlevania: Symphony of the Night on your memory card, Mantis will reveal that you are a fan of the series, and the same goes for Silent Hill, ISS Soccer, Suikoden and other games.
