Armored Core 6 (VI) - Mission 22: Attack the Refueling Base S Rank Walkthrough 

Can confirm reducing cost / reducing the expense is all that matters for this mission. I went with this exact same build and path, did 5 runs and they all end up with an A-rank. I was wondering did I not get enough credits at the end. I went down to shoot more fuel tanks and ended the mission with $390K earnings and still got an A-Rank, while this video ended the mission with $340K earnings and it has an S rank. Next minute I swicthed out the Hu-Ben Gatling guns for Zimmerman shotgun, only killing the Combat log LC at the start and rush straight towards the main objective, did not touch any fuel tanks. Blow up the factory, fight the 2 AC bosses, ended the mission with only $260K earnings but it's an S-Rank! Main difference is all my A-Rank runs has a total expense of well above 60K but my S-Rank run only has a total expense of 27K.

without a doubt, the hardest S rank iv had up to this point thank you for this vid, it really helped!

Thank you. I memorized your path/method of attack and worked like a charm after like 30 attempts trying to do it fast as I could on my own.

Just chipping in here, I struggled with this for ages and then on my last run made a huge effort to kill as many enemies I ran into as I could along the way while going as fast as I could and I got the S rank. Seems like getting the bonus points by taking out fuel tanks/enemies could play a big factor into getting the S rank for this mission

Like others have said, this one is about speed. I used mini tank with dual zims and needles. Went fast and only healed once with no resupply. I also killed the LC at the start of the mission, the one in the middle and killed two sets of tanks.

Thanks, I think to have S rank on this mission, you need to kill that loghunt dude at the start and have less than 15k on repair costs. Didn't need to break a single gas tank on my S run.

wooooof i finally got it. tried zimmys for awhile couldn’t get it switched to gatling and worked like a charm. skip literally everything except the loghunt LC at the beginning pretty sure you absolutely HAVE to kill him to get an S since i had an even better run earlier that was almost perfect, where i killed more enemies and my repair and ammo costs were lower and i still got an A (but i skipped the LC)

I was struggling to S rank it, your method worked just fine! Thanks my friend :)

Super thanks for making this, been a big help!

I killed the LC, then assault boosted all along the way to the reactor obj the best I could. Took minimal damage with the two ACs and got S-rank.

LC in the beginning is an absolute must for S rank. I only killed him and straight to the plant and got S rank after many tries not killing him. Credits don't matter.

I originally tried following this guide but was only getting A rank. I switched to dual Zimmermans with stun needles and said F it and took most direct paths to objectives, only killing the LC in the first third of the mission and ignoring the fuel tanks. I also made sure to destroy the refinery plant at the end first before mopping up the missile launchers and MTs for the two bosses.

2 min 55 sec final income 339 110 ( 121.2k bonus. 6.84k repair, and 15.25k ammunition cost) I finally got through it. Thanks for the hints, it turns out you have to go fast.

The pathing on this video is godlike. I tried both without getting any fueling tanks and getting all of them and they both gave me an A. On the one without it even had 4k repair cost which is nothing. But I followed this path once and immediately got the S.

Did this and it worked like a dream. was doing double needle/ double zim for like 25 tries did this first try worked,

In this mission try to keep your repair cost as low as possible, avoid resupply, speed also it is what you need here. I used dual zimmerman + Stun needle, kill the Lc in the middle and head fast to the objective, i didn't used any repair kit and it helped me to get the s rank, overall i did 3:14

Trying to get S here and my credit is 55 million because of this mission 😂

This run is super RNG dependant on the Ekdromoi. If you get hurt even a little bit it's an A rank. I have no idea how you pulled an S out of this run, but I can't replicate it 😂

Just do exactly what the video did if you still struggling getting S rank. I used the video as reference, but skip couple MT and thought it will be faster and easy S. But with better speed and low repair, never got S. Then I did the exact same route with same AB timing, same MTs to be killed, easy S

To anyone still doing this. Kill the ac. Made a difference for me. Time was 3:30 ish and still took 15k dmg

dude you may wanna run this mission again. cause this just went through an update last night and all of a sudden it's not give me an s rank. and truth be told, i didnt waste much ammo and didnt take too much damage.

Finally done, same built but with 2 Zims. First fuel tanks, enemy before the bridge and straight to the boss. RC 13.3K, AC 17.4 K.

my method was melee, kill only the log hunt dude and 2 dudes at the end fast (which is fairly easy with pulse blade and pile bonker), the same route as shown in this video, no repair kit, no resupply

Just did a run where I only killed the first LC and assault boosted to the objective. Got S rank with 250K but expenses were a little over 30k. I think the focus is to keep the expenses as low as possible.

I keep getting A doing this. Is it okay to take out more fuel tanks so the damage I take isn't as harsh of a score killer?

I did this mission with 5k cost and got an A because I neglected the fuel tanks. This guy hit the tanks and got to spend 10x on repairs and ammo. *clap*

Got S rank with $11k repair and $40k in ammunition cost

I try to keep ammo costs low and not use repair kits but it seems as if if you equip heavier more expensive weapons you get an S ranking if your ammunition exceeds your repair bills, whatever you can to keep yourself alive.

I keep getting A rank despite spendling less on repair costs, less on ammunition, and having more bonus pay

This is some absolutely BS mission, spent hours on it and finally did it by just killing the shield LC and Ekdoromai, nothing else. Didn't even resupply and didn't shoot a single fuel tank. Ended up with 6000/11000 health with no repair kits used at the end. One important factor that would help make this work is to use FCS - Ocellus that has 90 close range assist. There is another one with 83 close range assist, even that didn't help me that much, but Ocellus completely did. The only thing that was getting me every time is the final battle. Kept practising continuously by restarting from checkpoint in the final phase. (Didn't restart checkpoint during S-rank, of course). Eventually, this way worked for me. I used pulse armor, and I was peeking a little to lure their attention and get them to fire from long range, and then immediately got to the right side of where we start the battle(after the cut scene). Didn't hover much. Just stood my ground and was quick boosting while pulverizing the lance enemy first followed by the enemy with the energy weapon. Make sure to be in close range(within 130 m or so).

Can confirm this works and not only that, you can still take a bit of damage and still also get an S rank Had almost no health at the last fight but didnt have to use a repair kit and got S on the first try after seeing this!

What i've found: Speedrunning does not give S. Killing the LC before the bridge does not give S Killing the two bosses quickly does not give S Reducing the expenses does not give S Minimizing damage taken to less than 2k does not give S Ignoring the supply does not give S

The Gatling guns were proving too expensive for me, so I switched to double zimmy (keeping the stun needles on for the LCs) and S ranked first try.

I was trying to get all the fuel tanks thinking you needed them for S rank, I was coming out with like 100k more money, taking less damage, using melee weapons to save on bullets... Nope Just about speed I guess.

I did this and got an S with the same build but with dual Zims. I used gatlings on my first three attempts but struggled to get an S. I think ammunition cost held me back from getting an S.

Dual Zimmerman, Dual Stun Needles, Basho Head/Core/Arms, Fortaleza Legs, FC-006 ABBOT, VP-20D Gen Big tip is never let your energy run empty while assault boosting. AB until bar turns red then perform a quick boost and you should still have a sliver of energy left. This helps EN recharge faster. You need to immediately boost to the gap between the facility and rock wall to the front right of where you start and again down the road to get to the ramp. Up the ramp go straight for the LC and take it out ignoring all other enemies. Proceed in the same direction you were going, hop over the ledge and you'll see two circular cliffs to the right of the bridge on your side of the chasm. Get to the middle of the second furthest cliff ledge and AB across the chasm at an upward angle toward the pipes where there's another cliff underneath. This lets you cross without getting hit but if you go further than midway on the second cliff there will be snipers within range to the right of you that can pick you off mid-flight. Once across the chasm follow the ledges along the pipes, ignoring the resupply and following the ledge toward the dome. Once you're at about a 45 degree angle to the dome, AB off your ledge over to it and you should be able to land on the catwalk. Mind the missiles on your way there. Now within view of the core, pop one stun needle into it. One is all it takes. Immediately drop back down and begin taking out the 4-5 MC's/Missile pods since you have to wait for Handler Walters dialogue to end anyway before the boss fight starts. At the start of the boss fight stay on your level, and boost to the left where there's a square platform with a small ramp in the middle of it. You want to hide behind the ramp and wait for either enemy to get close, preferably the laser lance guy will lunge at you and get stuck on it. When they do, QB around so you're right in their face and hit him twice with your zims, this should break his stance or come very close. Follow up with two needle shots and be mindful his sniper buddy. By now he should be at roughly half health. The key in this fight is staying just around the corners of the small square platform until you reload and try to bait them close by peeking around the corner. It's super easy to get them stuck on the walls and corners where you can QB around and zim them point blank again. Once one is out of the picture do a similar strat for the other enemy, staying close to the walls and hoping they get hung up on it. If you're really good, you can fight them out in the open since you don't have to worry about being blindsided. It took me maybe 50 tries of various builds before I saw another person comment about zims and I was able to get this in about 3 tries after. From what I gather, damage doesn't matter, kills don't matter, speeding to kill the LC then killing the bosses quickly is what gets S rank. If you die during the boss fight you will get knocked to A rank or lower. Resist the urge to restart mission, just restart from checkpoint until you beat them to get the practice down while earning money, then replay from main menu again. Frustrating AF but you'll get it.

first 3 tries kept getting A, tried getting all fuel tanks on third run to see if it helped. fourth run, i killed the LC before bridge insanely fast and killed the last 2 PCA decently fast, got my S. was running double zimm and songbirds, hope that helps.

Did this build but with zimmermanns. Killed LC shield and did a pretty fast run. Only got 239,806 € but got the S rank. I think the key is to keep expenses low and do it fast.

I got brain rot from reading these comments because everyone said they figured it out differently, but for me, i just rushed the LC that they kill in the video and then rushed the exit. Got the resupply because im not sure if you get charged just for taking damage or using heals, then rushed the objective. Took half hp on the fight but used no heals

It was one of my favorite missions, now its a miserable experience and i hate that I began doing this s rank buillshit. Peace, from a loser who fails a lot

I’m convinced this one is all about keeping low health percentage lost (or just having high ap). I tried a bunch of times doing it fast etc and finally tried the tankiest slow build. Killed the first log mt, and then ran to the end and tried to take as little damage as possible. I didn’t do well but got S with over 10k remaining ap (without using repair kit). Summary: -Hi HP build -Kill first log MT -Get the supply sherpa (not certain this matters) -Obliterate the two end guys and try to keep high hp at the end

I just got this today. The run is based on how fast you get through it. Ridiculously so. You do NOT need to destroy the tanks or take out every enemy. The only things needing to be destroyed are the LC at the beginning, the station objective itself, and the two Erkdromoi. As someone mentioned in another comment there is some RNG dependency with the bosses. The faster you can stun them the faster you can deal critical damage with melee. I did it with the BUTTA blade, but the pile bunker and lance would be better. I didn't time myself but I think I finished it in just over 3:30. So if you're close to that time with both bosses still alive you may want to restart unless you can kill them both within 15 seconds. I'm sure your AP does matter here, but not as much as you think. I took about 1000 damage on the way to the end and during the fight I was left with just over 4100 AP left. I had a very light-weight AC with about 8500 AP and just speed past everything except the LC. Again, you do not need to destroy the tanks.

This S rank was so finicky. I went completionist, speed, no matter what I did it gave me an A rank at the highest. So dumb

I don't think I will ever be able to articulate just how much I utterly despise this mission. Edit: Has anyone actually done this since the patch? I've tried every method listed by people in the comments (speed run with minimal damage etc.) and I've bested the Powerpyx guide on all fronts (multiple times) and I cannot get this beyond A rank.

here it's all about bonus first and then low expense.. and of course time (cause one try I improved everything from this video in terms of earnings and costs and still got A)

At long last! I discovered how to S RANK it! First wait until you reach game++ then equip coral and moonlight blade and zimmer man shotgun with song bird on the right shoulder. AC parts are: shade eye Firmeza Basho arms for high melee damage. Firmeza legs BST g2/P04 boosters Abbot FCS for close range VP 20C and Pulse armor.

“Time to pay the piper.” Me: I am the piper.

Honestly dude fuck these s ranks it's not worth running the same mission 70 goddamn times

it’s like you might as well read the comments before even watching the video to find the stipulations for the level cause this guy ain’t telling you. Still appreciate the guide tho.

i tried this setup and I still get an A rank, like what am i missing

I have a playthrough w/me just doing the LC, LC Sniper, 1 MT, and no fuel tanks S-Rank w/no ammo cost (melee weapons only)

you really have to kill that first pca mech?

Speed, repair cost and ammo cost I think i got it with repair + ammo just at 50k

I think with missions like this and "Attack the Old Spaceport" the key to S rank is destroying a certain number of LC and MT to reach a certain level of collateral damage. Really any mission with extra rewards for enemies destroyed probably has a hidden threshold for collateral damage that has to be reached to get an S rank in addition to the normal conditions. Time and expenses don't seem to be the only key as I have done this mission with only destroying the bosses and only the bosses with all the fuel tanks with under 20000 in expenses and in under 4 min to get an A.

Id recommend ludlows instead of hu-bens then do the exact same route the ludlows are more cost efficient and have more attack power

497.000 income, A rank... So it definitely is about the time rather than the income...

My strategy for this was avoid combat and hit the fuel tanks. I more or less took the same route he did, quickly wiping anyone who got in my way with my pulse blade or six cell missile launcher. Fun fact, theres a set of 6 fuel tanks set up in a ravine. Multilock can do wonders. If anyone wants my build: HG004 DUCKETT HI32 BU-TT/A BML G2 PO3MLT-06 P I L E B U N K E R HC-2000/BC SHADE EYE EL-PC-00 ALBA AA-J-123 BASHO IB-CO3L HAL 826 FUEGEL/21Z FC-008 TALBOT IB-CO3G NGI 000 ASSAULT ARMOR

I just try everything I've see in this video and in the comments and absolutely nothing's work for me, so I diced that I destroy some folks to compensate the damage and amount ammo cost and I got a s rank

Basically just go as fast as you can, kill all the LC'S and take the boss pair of LC's out fast as possible, did it woth the build on the video my income at the end was 322,720 with like 45k in ammo cost and 19.7k in repair cost, disnt use a single repair kit

It's all about speed my fellow gamers. I ignored everything exept the LC in the middle. Go as fast as you can to that LC, kill it as fast as you can, dash to resupply, use it, dash torwards the right side then straight to the plant, kill bosses fast. My build was just the lightest AC I could make that could hold 2 songbirds, one long range shotgun, and the melee lance on the left. HD VERRILL head, Schneider core the light one, JAILBREAK for arms and legs, BST G2 booster, FCS G2 for range assist, VP 20D for generator, nothing for expansion. I was considering the use the shield thing for expansion, the one that damages enemies when activated but I did it without it. I m not that good at the game to make and use a glass canon build but that s the criteria. High speed and dmg, ignore everything but the LC. Hope this helps my fellow trophie hunters.

Beat it as fast as possible, killing only the necessary targets and didn't get hit. Got B. Fuck this mission. Edit: Got S rank, I killed the LC and ignored all fuel tanks. Killed like 4 or 5 goons on the way and my main focus was getting to objective as fast as possible. Then killed last 2 boss with zimmerman + needlelauncher.

Ridiculous, i have 170k bonus, 24k ammo cost, yet 30k repairs knock me out of S-rank, you're gotta be joking, game -_______-

Kinda strange, it doesn't work. I get less damage, and use less ammo, do as fast as possible, even faster than in vid, but anyway get an A rank

For those who are still need s rank: try it with Double Zimmermann instead, to minimize ammo cost and just skipp the tanks, also try not to heal/resupply, hope that helps

Tried this and still can't get s rank... On the other hand i got a ton of credits now lol

For anyone wondering the Bonus Pay doen not matter. What matters seems to be low rapair cost and speed. Just skip everthing (The fual tanks, any small enemy) except for the LC maybe. Then just head for the boss fight and I'd recommend killing the dude that has the melee first. I got S-Rank with 7K repair and 33K ammo cost. Bonus pay was only 56K.

I did this and still got A rank?

I think the patch BUGGED some missions.

Ammo cost...it was ammo cost.🙄

Too bad needle cannons are nerfed now

This mission is impossible to s rank

Can you do ace combat 7 walkthrough as well

Impossible

No one knows how to get S on this mission, not even fromsoft

Can confirm what everyone else is saying: hit the first LogHunt LC, then beeline to the bosses and don't bother with any other enemies/tanks. S rank first try at 244k (>10k repair costs), A rank multiple times at 390k+. Good luck out there Raven 🫡

Yeah pretty easy to beat it when you have shoulder mount weapons NOT AVAILABLE UNTIL AFTER YOU BEAT THAT MISSION.

I'm gonna lose it. I'm doing damn near WR speedruns taking almost no dmg spending little ammo. What do they want from me??

This mission seems to be all about speed. Higher bonuses and lower repair/ammo costs didn't seem to help me out much. Just focus on the fuel tanks (just in case) and (for some reason) the shielded lc in the beginning. When I avoided him I never hit S, but when I took him out I managed to get it. Don't know if it's related or not but might as well since he isn't too hard to get.
