Top 10 HARDEST Bosses in The Metal Slug Series 

For me, the hardest boss of the series will always be my parents. Convincing them to lend me another quarter was among the toughest challenges I've faced in any game

the art style of this game is timeless. Metal Slug is ace stuff!

I think one of my favorite lore tidbits is that apparently the reason why Allen never dies is His love for his wife and child and his absolute refusal to fail to return to them. Also I'd have to say the Monoeyes tend to be my nemesis. I can either do really well against them. Or I struggle against them. There doesn't tend to be a lot of in between for me.

Ah yes, the most persistent boss/character ever, Allen O’Neil

Dude, Rootmars is freaking as hell. His appearance should be more than enough in why he’s a tough boss. He’s just so creepy to look at! I salute you for being able to face such an abomination.

The handsome leader of the Mars people with a cute angelic laugh" Me: *remembing calling Yamazaki the nicest and most considerate human being ever from ranking the KOF games from worst to best video* 😂 👍

Metal Slug was the Dark Souls of all side-scrolling shooter Games.

Yes the Kraken is so damn hard and the timer running out makes this boss hard to do a no death run

That weird floating red thing was indeed hell

Rankings of SNK bosses are always fun, thanks for this one. And depends on how much you consider Metal Slug Attack and Metal Slug Defense as canon but Amadeus does survive his boss fight and goes on to create an entire faction to keep being a pain in the ass.

I grew up playing this. It was so addictive with a very fun first stage and then a parade of getting bent over. What a stunning game though. So much work to make it look the way it does.

I remember playing metal slug x with a friend from college we were on a roll steamrolling all the levels until we got to the final level. We both spent about $1.75 to beat it but damn we were in sync that day

16:31 You can hit the boss with grenades if you're playing as Eri, since she gets extra range with them.

Ahh..I still remember went I was 12 years old I play all metal slug until midnight. When I was destroy Brian robot I look at windor, I can see sun coming up and my brother wake and saw me still playing metal slug. He shock, he can't believe Im not sleep until morning. I ran to my bed and get sleep before my mom know I not sleep becaus playing games. I miss my childhood.

"In my case I was more lucky than skilled" you described every win I ever had at any Metal Slug game 🥲

I remember using 39 coins to complete metal slug 3 it was hard lol and at that time getting 39 coins was hard tho , this game made my childhood great

Video Idea: Top 10 hardest bosses in Samurai Shodown, Top 10 KOF pairs shipped by the community

mission 4 will always have most of the toughest bosses in the series.

The hardest boss in Metal Slug......my lack of quarters to play these wonderful games

That Stage 4 Boss on M3 is Hell with Lvl8 difficulty

Never played Metal Slug, but I intend to now!

shoryugame put some funny lines in this video. i laugh so hard when he show how marco missed the hit on rootmars

Metal Slug 3 is the hardest in my experience, It's no surprise to see so many of its bosses featured here.

Well, I had played in my computer so me losing my life was not an issue with extra credits in the arcade mode. On Console mode though well you are right about the difficulty. I had to resort to the arcade mode to clear the game.

Bit of a trick with Brain Robot: holding the Fire button with the Protogunner will activate Vulcan Fix and keep the gun in place, allowing you to focus on dodging. Also, his enrage only triggers once he has used his melee attack several times.

12:06 "And his aiming sucks!" I died of laughter after hear that xD

"His aim sucks" Made me laugh g00d :) Excellent vide0 yet again SG. Keep it up.

I loved the satisfying "Battle Machine Gun" sound effect

Never played metal slug but now I see why it's so beloved. Man these bosses are insane

The brain robot was the hardest boss for me. I kept on dying and he took FOREVER to kill.

The third place is reserved for Metal Slug 3's main antagonist, the handsome leader of the Mars people, with a cute angelic laugh. *Rootmars.*

My day is made. Thanks for the video! :D

Also Kraken can took so freaking long to beat, even if you can dodge all those still risking the death from time out which is pretty hard to happen normally.

14:56 Breh, you got us there near the end. Solid Gold!!!

Just when I finished watching your "Metal Slug Story Explained" videos. Amazing!

I can’t wait to build my home arcade to play this series. Thanks for the motivation to get back to it.

My personal hardest will always be the Avatar of Evil from MS5. Holy crap that thing is intimidating, but man is the sprite work so good.

16:28 Correction: You CAN hit the kraken with grenades if it hasn't finished submerging or when it comes out of the lava OR using Eri since She can aim her grenades in 8 directions depending on the D-pad presses(If it's flying, hold up. If it was submerging, hold left or right.).

I play all arcade versions expect the ones on Playstation. That final boss in metal slug 2 was epic! So glad it was on this list.

The best thing about the Kraken is that, since it's a very long fight, even if you know how to evade all its attacks, the timer will kill you it if you can't deal enough damage to it

DANG! UR VIDEOS ARE JUST TOO GOOD MAN!! Also, I have an idea! Can you make a video about Top 10 Hardest Bosses in The Samurai Shodown Series? I think you must include all the games in the Samurai Shodown Series, because the mainline games don't even passed more than 10 Bosses. If you ever make a video about this, you always will have my sincere gratitude! Thanks buddy! Ur the best RU-vidr ever for me! 😊😘👍❤️😍☺️

14:51 u rlly made me audibly say really? lol u got me bro

Very refreshing to see a Metal Slug video once in a while! I really need to get into this series someday... what is the best way to play Metal Slug nowadays??

Yeeeeeiiiiii, Metal Slug!!!! (And clark in flames 5:35 😂). I would like to see a top of indigenous and native characters in Fighting games such as Rick Strowd (RB2 Fatal Fury), Julia and Michelle (Tekken), Nightwolf and Kotal Khan (MK), Thunder (Killer Instinct), White Buffalo (Power Instinct), Mudman (World Héroes), Tam Tam and Cham Cham (Samurái Shodown), T. Hawk (SF), and I am not sure if Tizoc (Garou/ KOF). Greetings.

12:06 His aiming is as bad as the aiming of the StormTroopers from Star Wars 😆 I am not a big fan of Metal Slug but I still remember the day me and my cousin beat Amadeus. Maybe that is why Metal Slug 4 is one of my favorites.

10:00 You can stand in open space of the laser parts (between of laser shootting down) and when he begin fire big ring laser,jump immediately! Trust me, I play Anthology on my PS2 almost every days :) Hope this can helpful!

You’re a Neo Geo God So much knowledge

14:55 this bait and switch was hilarious lol

hey, shoryu, chris's gameplay trailer on KOF XV is dropped. l'm so happy to see team new faces / orochi is back since 2002.

I love all of your metal slug videos you rock buddy! Like be an always support the channel

i LOVED Sand Marine and Fall Mecha, one of my favorite bosses in the series, but they are quite a challenge. really liked the two O'Neil fights on the list, didn't really like the Sol boss, Brain Robot is cool but i hated how it goes from hard to absolutely painful if you try to use the vehicle there, really liked Amadeus, Rootmars is pretty neat even if way too repetitive and high on health for me, HATED MS2's final boss and loved the Kraken boss. great video!

8:52,I'm super late, but the proto gunner has the Vulcan Fix built into it, so just hold down fire to constantly aim in one direction while moving around!

I'm happy with any video.. Time to watch the metal slug lore videos again after so long 😁 Thinking of playing the metal slug games for first time on mobile now🤔

Amadeus also has a very awesome musical theme. Which is just perfect for him

You cannot grasp the true form of Armadeus's attack! You took mortal damage.

I don’t know if this counts, but the hardest thing about the MS series for me were the controls. I could never get used to that aiming style...

best stages in metal slug need a video

13:31 he died as Hero rest in peace pilot rebel guy

i absolutely agree with kraken being #1 because kraken has three thing: -The Tentacle part are hard - Kraken part are also hard -Trying to defeat it without running out of time and dies(there was a super pro RU-vidr that did All Metal Slug Bosses with without being hitten, well he is not hitten by kraken but Die by running out of time when Fighting Kraken)

"There are those who could defeat these monsters blindfolded while holding the controller with their feet" 😂😂😂 I'd like to know those monsters who can do that!!

He's not wrong about the number one. What makes it even harder is that if you're fighting the Kraken on hard difficulty and you're on a "No death" run. The boss won't kill you, the timer will.

Another infuriating thing about the Kraken is the time limit, which kills you when you reach 0. For me, the hardest boss is the Monoeye aliens from MS3, as a Zombie, you have to time it right with the blood vomit while dodging the beams.

03:48 The boss name is now Fall Climber.

I love your videos ❤️ man you accent looks so Moroccan 🙂🙂🙂

Hello shroyu Can u plz briefly explain the story of those from the past?

I had a grudge for (also) the mission 4 of Metal slug IV... I couldn't progress on the arcades because of it (Played with my brother and we had a limit of how many we could spend), and Big Jhon was tough to deal with those glass bombs that killed you even in zombified state... good old times

There's a line beyond a challenging boss becomes simply idioticly unfair.

Metal Slug has insane boss designs

I have played metal slug 1, 2, X and 3 on the Arcade when I was in studying though the Arcade is closed now.

You could also make a video to rank the different factions based on how strong they each are both gameplay-wise and lore-wise. My list (only lore-wise), from most powerful to least powerful, would be: 1) Future Rebel Army 2) Mars People 3) Invaders 4) Present Rebel Army 5) Ptolemaic Army 6) Amadeus Syndicate

I like your videos. :)

Hey I've got an idea Since you made a video on the best songs of KOF, why won't you make one for the best songs of Metal Slug. That game definitely has awesome themes ( with Secret Place from MS 4 being my favourite ) What do you think ?

Metal Slug 7 is what I think the hardest game in a cheap way. While the enemies aren't so creative, it just likes to take advantage of the terrains and platforms making it hard

ShoryuGame: No.1 is the Kraken Me: Yup, sounds about right.

1. Sol De Rokkie is my Nemesis, even he has a "trick" is not easy to pull off, also i fought him since 2000 when MS3 came out in arcades and let me tell you: try to fight that bastard in lvl 8 difficulty (which is ever put in that number in the arcades for you to lose your money) is a nightmare, i even learn to pass all the game without problems and no deaths before and after him in lvl 8. but that boss...ArgH!! it die with 27-30 shotgun shells or if you for the upper path, then fire is very useful against him. 2.After that the Sandmarine (MS5), i remember come to him with 40 bombs and still that bastard don't die (lvl 8 of course), 3.Final boss MSX Rugname. 4. MS2 Robot-Morden mission 3 WITHOUT the fire weapon, it just have sooo much defense and hitpoints and also survive the 2 helicopters above you meanwhile you are cornered, with the fire weapon is all opposite: too easy and die in few shots. 5.Kraken MS7, even he has many attack, you still can "learn it" 6.Invader King, still don't get the right pattern 7.Brain Robot, yeah he is an asshole 8.The Union MS7 XX 9.Amadeus and 10.Sea Satan from MS4: both have the same thing: Is just know where positioning to avoid bullets... the problem is remember where is and they change that position every time Some Mentions: -Is not a boss but try to pass the last 3 trains mission 5 in MS2 is hard, because there is not weapons for you when you get there or bombs (you have to save bombs until get there) -The submarine of 5th mission MSX WITHOUT any vehicle in lvl 8, i learn this trying survive mode in playstation 1 I find the O´Neil from MS4 actually easy (even in lvl 8): just let yourself shoot with the tank meanwhile you are jumping to go up the platform, from there no bullet can reach you, and you just shoot the upper section (the one barely you see in the top) when explodes (looks damaged but still is there) then just shot in the front of you trying to shoot the two low sections at the same time, when one of the sections is destroyed quickly try to destroy the other, and since the top part is already destroyed, you get to the last part with the cannon grounded in the floor, and since you are in the platform, just shoot all the incomings flying bombs with the tank and shoot the last part with no problem at all

Yes i like 😁 Metal slug😘 I like your video🌹💖

While I never plaed metal slug, I did play commando growing up which was a flash game that, upon looking back, was heavily inspired by metal slug

The Invader King by far is the hardest for me.

Pls do a worst to best of the main Metal Slug games

Timeless but still my most best favorite game ever

For me based on Lv.8 Difficulty (hardest difficulty) playthrough experience Hardest No.1 Amadeus last phase No.2 Sandmarine No.3 Sal Dae Rokker No.4 Rugname No.5 Kraken No.6 Rootmars Also MS7/XX Mission 4 , 5 boss Jupiter King if fight without Rebel's LV Armor When you come from Ostrich route you don't have vehicle to fight this boss if come from secret base route you'll have LV Armor at least you can use eject trick to avoid dmg Invader King if fight without Slug (fight is easy with Slug + Tarma because when Tarma ride a Slug Vulcan dmg is x1.5 and can take 6 hits while other chars when ride a Slug can take only 3 hits) Elder Centipede (MS6 mission 4) fight is harder without Slug Flyer (Slug Flyer destroyed during Slug flyer route or during boss fight or come from Rootmars route) All MS1 bosses are easiest bosses even Lv.8 difficulty especially when fight with Slug + spare alot of Grenades (40-50 if possible) before fight you can spam it and kill the boss quickly

Great job like always have you played that fatal fury fan made beat em up

Dude that story of the dude who got all that help and still lost I feel really bad for him

Wondering when he is going to a stroy explain for the new metal slug.

I just recently played Metal Slug X and I have a personal grudge against the tank of the first level, just beacuse each time I attempt a perfect run of the that stage one of the three final dudes to rescue (from destroying the bottom turret) always goes off screen and my attempts to catch him always end in a missile stunning my metal slug and messing up the run.

I can easily do up to the monoeyes in MS3, they always mess me up badly.

I forget how hard these games are due to unlimited continues

Wow i really miss this game 😔

ooh, another video maybe, best weapons in metal slug, or maybe best vehicles.

Well, when the Kraken submerges, it's a good time to grenade it.

I remember getting super bummed out when I nearly beaten Metal Slug 3 in 1 life then started losing a continue at the final boss on hard mode. So I kissed those achievements for no death on Mission 5 and no continue run on xbox live. The final mission is about as long as doing mission 1 to 4 in MS3. I wouldn't say this series is bat shit hard compared to contra where even touching an enemy in those games kills you. In metal slug the attacks are heavily telegraphed, each enemy action needs purpose for why your protagonist is getting harmed.

If there's one thing that Metal Slug 4 did well, I think it's the final boss fight. For many reasons, I feel that Amadeus's fight is the best boss in the entire series, and certainly outpaces many of the other final bosses. For example, Rootmars simply involves jumping in and out of the Metal Slug while he repeats the same two attacks over and over again, while Dark Spirit Incarnate is literally just sliding left and right and waiting for his scythe to fall down. The Rugname final boss from MS2 literally just fires blindly in the middle and spams annoying over-buffed U.F.O.'s for the whole fight. Compare this to a climatic three-phased boss fight full of fun and dodge-able patterns against missiles, laser rings, energy balls, mobile satellites, a giant buzzsaw, a machine-gun, central cockpit heat lasers, vertical & horizontal beams, mini-robots and bouncing shots. The atmosphere is intense, it always keeps you on your toes and has high replay-ability because of the sheer diversity of attacks it has. Now only if Metal Slug 4 had this much ambition in the entire game, and it could have been one of the best entries in the series.

how hard to you want to make your bosses snk: yes

My god I wasn't aware of Metal Slug 6 and 7

Do a video on Metal Slug Attack

Rootmars still give me nightmares

Though I agree with most of them but Union should have been there. My goodness,that thing was a nightmare. For me invader king is the hardest Metal Slug boss of all time

Man, Sol Dae Rokker is the worst for me. I remember my mom being so mad at me because I was so pissed off that this boss was so hard to beat. Good times.

1:24 that one took me so many credist, I'd say he's number one.

I used to be able to reach the final mission of MS2 with 1 coin. good times
