I. Introduction (INTRO)


Metal Gear Solid 4 is finally here and it was well worth the wait!

The Metal Gear series is known for its clever and thought-invoking

boss fights, and MGS4 is no exception. Many of the bosses are very

challenging this time around and considering how many of the bosses

possess superhuman abilities and suits, many of the bosses take many

hits before going down. However with the right strategy, each boss

can be taken down. Well that’s what you’re here for anyway, right?



II. General Tips (GENTIP)


1. Use your Octocamo – Just because it’s a boss fight doesn’t mean

stealth isn’t important. Bosses that become confused and unaware to

your presence will allow an easy shot.


2. Pay close attention to your psyche. – The psyche gauge is just

below Snake’s health bar. The higher the bar is, the greater Snake’s

psyche is, and thus, better performance. High amounts of stress in

combat will cause his psyche to deplete gradually; this occurs

frequently during bosses and will drop your aim considerably. Eating

noodles, drinking Regain, smoking a cigarette, resting, reading a

magazine and the syringe you receive later on all help keep the

psyche meter high.


3. Take cover often and rest. – If you take a lot of damage and don’t

have much recovery items left, find safe cover and have Snake rest

idly as long as possible. Snake’s health will gradually restore

itself. The higher Snake’s psyche gauge, the quicker it will restore.

The higher Snake’s psyche gauge, the quicker it will restore.



III. Bosses




1. Laughing Octopus (LOCT)


Difficulty: Medium


The first boss you fight, it seems like quite awhile before you even

fought one. Unlike most first bosses in the series, Laughing Octopus

is not a push around and can deal some serious damage if you don’t

think on your feet.


Octopus will rely on the same technology – Octocamo as well as

facecamo which allows her to take on the face or even shape of

another object or person. Because of this, it’s important to keep

note of your surroundings and any changes.


If you are going for a tranq kill, prepare for a long fight. Stun

Grenades work well here, as she will usually deflect your MK bullets

with her tentacles. Fighting her upfront as she is approaching you is

usually useless in this sense.


She will primarily attempt to fool you by using disguises and

blending into the environment. Using your night vision on the Solid

Eye is a good tactic for discovering where she is. Pay close

attention to the radar as well, she will frequently yell and give out

her location. She will not move from her position until you shoot her

out of it. Make good use of this advantage and rest to recover health

when needed.


Occasionally, Octopus will send out these small floating red orbs

that will attach themselves to you if they touch you. You can either

shoot them in the air or roll if they attach to you. They will

explode after some time if you run away from them as well.


Be careful to maintain distance from her as well, her tentacle attack

has range and can deal a large bit of damage. Be especially careful

of her rolling attack which can catch you extremely quickly and deals

massive damage if you are hit. Find a crate to go up on if you see

this coming.


Normal weaponry will take awhile to bring her down with, any heavy

assault weapons will bring her down faster. If you are just going for

the facecamo, you can lethal kill the beast.


After you kill Laughing Octopus, she will shed her protective armor

and enter human form: Laughing Beauty. I don’t really consider this

its own boss fight so I am including it here. All you must do is keep

shooting her as she slowly walks to you. There is no reason to get

hit at all, and if you do she will try to choke you, in which you can

easily shake her off. I recommend stamina killing her for her

facecamo. You will eventually land shots and bring her down

regardless of her dodging.


Congratulations! You have beaten the first boss.



2. Raging Raven (RRAV)


Difficulty: Medium (Another long fight)


Another fairly long, but not too difficult boss fight. Raging Raven

possesses other unmanned flyers which fire missiles at Snake, making

the fight a bit more of a headache. Unlike your fight with Octopus,

you are given a much larger battlefield to maneuver in. Personally I

fought this battle on the roof, but it is possible to win it on the

lower levels, I just feel it is harder to win it there.


So with that being said, begin the fight by making your way to the

top of the tower. You will encounter a large amount of the unmanned

flyers here; take them all out with an assault rifle, which will

force Raven to make her appearance. She will usually stay in one

position for a few moments before flying to the next one, allowing

you to hit her with your best weaponry. Be careful however, she will

fire missiles at you while you are shooting; hit-and-run shooting is

the way to go. If you are hit with the missile Snake will go flying,

and can even fly off the roof (instant death). Luckily, it does not

deal a large amount of damage.


If you have the RPG-7 and have well aiming you can deal heavy damage

to her if it lands. Handguns and assault rifles will make this LONG

fight. You can also attempt to snipe her head if you can aim well.

Either way, this fight tests your ability to aim quickly, as the

unmanned gliders are also difficult to shoot down at times.


Occasionally, Raven will overheat and throw a Stun Grenade at you.

Quickly equip the Box or the Drum Can to resist the flash once you

hear her say she is overheating. This will give you a few seconds to

shoot her some more. She will then fly over to one of the far roofs

and rest for a moment. You will notice many flyers around her as

well. This is a perfect time to snipe her or fire a missile at her

for easy damage.


If you wish to rest and recover naturally, go back down into the

tower and go down the first set of stairs, but rest at the wall that

is there before the next set of stairs. I never got hit here once,

even with Raven shooting missiles at me.


Once you deal with Raging Raven you will fight her human form, Raging

Beauty. This is the exact same battle as when you fought Laughing

Beauty. Tranq her if you want her facecamo, otherwise you can kill

her quickly with the RPG-7.



3. Crying Wolf (CWOL)


Difficulty: Easy (with Solid Eye NV) Very Hard without


Similar to Raging Raven, you will also have to deal with FROGS during

this fight. Make good use of your Octocamo here and pick them off

one-by-one. I recommend equipping a suppressor to whatever gun you

use so you don’t get an alert.


Solid Eye with Night Vision is ESSENTIAL to make this fight easier.

You will be able to track Wolf’s unique prints in the snow, and track

her down when she moves positions. It will also allow you to see

through the intense blizzard. Projectile missiles are also essential

to deal good damage to her. Sometimes she will appear out of her

protective wolf armor, in which you could snipe her, but she can

detect you from far away and will send her own missiles at you.


Sometimes she will charge at you and will jump on you. If you want

too long it becomes unavoidable, it will deal massive damage to your

health AND your psyche gauge. Stay moving at all times if she is

running to you. You can also attempt to shoot a missile at her if you

are quick enough, but it is risky.


Basically repeat this until she dies. You can easily track her

movements with the Solid Eye on Night Vision, so keep that on at all



After you beat her, she will become Crying Beauty. Same deal as all

the others. Either tranq for facecamo or kill lethally however you




4. Vamp (VAMP)


Difficulty: Easy (if you know what to do)


Vamp is a pretty straight forward fight, attack him with an assault

rifle at his head, and gradually bring him down. He will mostly jump

around places, but will sometimes make a large leap at Snake. Use a

side roll to avoid it. He may throw knives at you as well; you can

either take the damage or run away from them. They do not do that



Once you bring his health down to zero the fight seems over. After

about 5 seconds he will get up again and the fight will resume with

him at full health. This can continue forever if you do not stop his



To beat him, get behind him once he falls to the ground after you

defeat him. Make sure you have the syringe equipped. Once he is up,

quickly hold down R1 near him and you will grab him in a CQC hold.

Make sure you have a handgun, knife or no weapon equipped so you can

grab him. Assault rifles do not work properly. Once you have him

held, press the action button (triangle) and you will inject him with

the syringe. The fight will then be over.



5. Metal Gear Ray (MGRAY)


Difficulty: Easy


Could you ever imagine such an epic battle…? Metal Gear REX vs Metal

Gear RAY. Ray was designed to eliminate all other Metal Gears, but

this fight is actually quite easy, as long as you are aware of Rex’s

abilities. You can change which weapon you use from the weapons menu.

You can employ each of Rex’s weapons used against you in MGS. This

includes the gatling gun, the homing missiles and the rear laser.


The rear laser must be charged before it can be used. You must hold

down the aiming button to charge it. You can actually charge it all

the way to level 5, which takes some time, however it has the best

damage you can deal to Ray, I would recommend using it often.

All three of the weapons will overheat if you use them too much, so

switch to another weapon when this happens, fortunately they cool

down quickly. Use the missiles as a good alternative to the laser;

just make sure you have a clear shot to fire. I recommend switching

between the laser and the missiles; the gatling gun is not worth it.


Ray’s attacks are all similar to the ones used against Raiden in MGS,

including the missiles and the ’water cutter’ attack that it used to

escape the tanker. The water cutter attack is very powerful, stay

moving frequently to dodge it. Ray will also attempt to tackle Rex,

and jump on it for a large amount of damage. Use the X button and

dodge to the left or the right to avoid this. After you have done

that, get close to Ray and wait for a signal for the action button to

come up. Rex will then grapple Ray in its mouth and hit it with the

rear laser to deal a large amount of damage, very cool to see.


Overall this fight is quite easy, and I find REX actually has the

advantage over Ray here. Focus on using the laser and missiles as

your primary attack, and use the sidesteps to dodge when needed.



6. Screaming Mantis (SMAN)


Difficulty: Easy (once you know the proper strategy)


This fight is extremely nostalgic to Psycho Mantis, and you will soon

find out why. You must protect yourself, as well as Meryl’s own life

from Mantis’ control.


Begin the fight by immediately injecting yourself with the syringe,

the actual fight will begin once you do that. If you look carefully,

you will notice two dolls to the left and right of Mantis. A Psycho

Mantis doll and a The Sorrow doll. You must shoot these, not Mantis

herself. Be careful of the floating FROG corpses, they can shoot you

or stab you if you get too close. Once you shoot either doll a few

times, Mantis will begin to manipulate Meryl more and have her attack



Take cover behind one of the pillars at the top of the stairs, and

Meryl will leap over to you. Grab her using a CQC attack (remember

only handguns, knives or unarmed for a grab), make sure the syringe

is equipped, and then press the action button when she is grabbed to

inject her with the syringe. Basically this is the exact same thing

you did to Vamp. It will instantly knock her out.


Once Meryl is knocked out, continue to fire on Mantis’ dolls. After

another few more hits, Mantis will raise Meryl once again, and put

the gun to her head this time. Quickly go down to the center of the

battlefield and grab Meryl in another CQC hold and inject her again

with the syringe. The FROGS corpses will most likely be near you and

will attempt to stop you. Keep trying to hit her with the syringe if

they land a hit on you.


Once you deal with Meryl again, you will finally be able to kill

Mantis freely. Continue to work on whatever doll you were shooting at

the time, you will notice it gradually fall from her side. After

about 10 hits or so it will fall from her side and fall to the ground

nearby. Quickly run to where the doll fell and pick it up before she

does herself.


Repeat this for the second doll. Be careful of her warping and slash

attack, she will scream "SNAAAAAKE" before she warps to you, giving

you plenty of time to run away. Once the second doll falls, you can

now kill Mantis. Equip the Mantis doll and fire off the projectile at her.

If it lands, you will be able to string her up like she did to the others.

Hold L1 and keep moving the Sixaxis back and forth between you and the screen,

this will shake her and inflict damage to her. You can kill her in one go

with this, quickly ending the fight. Note that both her stamina and health

gauge will deplete together.


You know the drill now, either tranq or lethal kill Screaming Beauty

to win.



7. Liquid Ocelot (LOCE)


Difficulty: Varies. Fairly difficult overall.


The fight you’ve been waiting so long for is finally here…Snake VS

Liquid Ocelot, and boy is it an epic fight.


There are four stages to his fight, the last one being very straight

forward. Each stage represents a progression from MGS1 to MGS4, each

to music from the respective games, very nostalgic.


Each form of Ocelot has his own unique move set, some easy, some more

difficult. You will first begin to MGS1 music and fighting a very

similar style Liquid. Press Select to bring up the controls for Snake

if needed.


Sidesteps are a good way to avoid blows and get a combo on Liquid,

you can also block his attacks and counter with your own. He can use

the running head butt attack similar from MGS1, it can be blocked but

it will break your guard. Keep dodging, blocking and delivering

combos and eventually you will come to…


MGS2 Liquid Ocelot, the alert music from the tanker will now play. I

find this form most easy to beat; Liquid will focus primarily on

using a powerful lunge fist which will deal a massive amount of

damage if it lands. Sidestepping will work best here to counter, but

even blocking gets the job done. Once you dodge the attack, you can

either try to get a combo on Liquid or do dash punches (Forward + X

combined with R1). Playing defensive and dodging is the way to go on

this form.


Eventually Liquid will change fighting styles once again, to reflect

on Ocelot from MGS3. Snake’s name will change to ’Naked Snake’ and

Liquid’s to ’Ocelot’. The theme for Snake Eater will now play as

well. Ocelot will focus on short-range CQC attacks. Do not use the

dash punch now or it will most always miss. Being aggressive with

combos helps more, as well as the occasional ducking and

sidestepping. If you are caught in a hold, hit the action button

quickly when it is displayed and you can break the hold. If he gets

you in a chokehold, rotate the left analog stick as quickly as you

can to break free.


Once you deal with Liquid a third time, the music will change to ’Old

Snake’ from MGS4, and both fighters will move very sluggishly towards

one another. You will only be able to swing using R1 now, make sure

you are close to Liquid before pressing R1. Keep mashing the button

to keep striking Liquid consecutively, if you wait too long then

Liquid will strike back. You can actually die on this part if you let

Liquid continue to counterattack, then you’ll have to start all over

if you do. Keep this up, and eventually the fight will end.


Congratulations, you have beaten the Final Boss in MGS4. Enjoy the

lengthy but enriching ending!



IV. Additional Tactics


Here I will post strategies and tips sent to me by e-mail. If you want to

submit your own just e-mail me at my contact info below.



Laughing Octopus



While I was fighting the Laughing Octopus, I’ve found that the survival knife

is a good way to do some decent damage and save ammunition. Here are a couple

of examples, one-when she first uses her camouflage and stands against the

wall (I am quite sure you know what I’m talking about), I usually run up to

her and pull off a knife combo, afterwards, she would still be standing there

and so I would pull off two to three more hits before she would fall to the

ground. This did alot more damage than I expected by the way. Other examples

are very similar, and this when she either hides on the wall over the

painting, hiding in a box, lying on the floor as a FROG, disguising as one of

those human figures, or lying on the floor with her face disguised as Naomi.

The technique applies to All the examples. Also, I want to point out that

when she does disguise her face as Naomi, you can still slice and dice her

even as she is spewing out that ink. if Laughing Octopus is lying on the

floor disguised as someone else, be sure to attack her in First Person mode

while crouching to hit her. This is only if you don’t have the auto aim

function enabled.

This is an interesting bug I found when fighting laughing octopus.


There should be a room where 2 boxes stacked on each other. Get on the

highest box and wait there while facing the door. She will continually walk

past the door and shoot at you. Since there’s a wall, her bullets will not go

through. But if you shoot at her while she’s shooting at you, you can still

damage her. This mostly work when she’s at 50% life/psyche, and she will

eventually move away to hide. If so, just go ahead and leave the spot, shoot

her, and run back on the top of the box.

Raging Raven


Nothing here yet!



Crying Wolf



Get under the tank, and equip Night Vis. Preferable weapon is sniper, for

when she runs into the woods, because she opens her armour and you can crack

off a great shot that’ll significantly lower her health. The worst that can

happen is that she attacks the tank and you lose about 1/5 of health (if

that…) which recovers quickly either. Whilst she’s running around it’s fun

to pick off the FROG’s too ^_^.

-Submitted by Bo17



After the cutscene ends and you regain control of Snake, duck under the truck

parked near you. From there, by using the Face and OctoCamo, you’ll be 99%

invisible. The soldiers looking for you will search the area, and it is broad

enough that you can snipe them with head shots. I used the M1 because it has

a good scope without having to customize it, and you’ll just need 1 shot to

take out the soldiers, as well as being silent. Its range is great, too. The

best bet is to snipe them in open areas where others can see the body.

They’ll go towards the fallen comrade and kneel to check their status

(perfect baiting technique). Once you dispatch them, it’s one-on-one against

Wolf. Stay where you are and wait until she comes into an area you can see

her. Once she pops her head out to scan for you with the rail gun, shoot her

in the head, wait for her head to recoil, shoot a 2nd time, wait again, shoot

a third time. She’ll get back into the machine and run off. Rinse and repeat.

Every 3 head shots took a quarter of her life, so I did this 4 times and

finished her easily, but not quickly. It’s a sniper showdown, so if you’re

patient, you’ll get the best of her. The second half of the battle when she’s

Crying Beauty is the same as the others. I’ve only beat her with lethal

means; I have not attempted this with the Mosin Nagant or the Mk22.

Liquid Ocelot



I found out of a tactic that works pretty well.


MGS1 Fight:

Go for the Big punch here. Punch him on so he is near the edge and continue

with the big punch. Be sure to press the punch button two or three times

since he will nearly fall of the edge the first time. When he rises continue

to punch him and you’ll take him down easily.


MGS2 Fight:

As you mentioned, he will focus on the powerful hit. Just step aside when he

is about to hit you and the Big punch him or combo him down. CQC and grab him

works well too.


MGS3 Fight:

I did go for the same tactics here as Ocelot did. CQC and choke him to

deplete his stamina bar wich will deplete his life bara when his stamina is

down to zero.
