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.
