The only tip I have is to somehow get a mech with at least 45000hp, very strong wepons since you need your ammunition to last 4 rounds of really hard fighting and be fast to avoid most of their bullet
s so you dont die in 5 minutes time.

Restart your campaign by clicking new game and just choosing to save in an empty slot. Unless you're wanting to complete it though - sorry but you ain't taking your parts with you I'm afraid. I had enough trouble with Wynne D and that other nutter. No tips on the 4 Collared's i'm afraid =/

Did it today after 50 game hours. Medium mech, integrated machine gun arms big laser cannon (single firing for more ammo) really fast and PA molders. Use PA armour attack as they're all approaching to start then QB all over. No easy way, hardest mission I've ever done on any computer game ever
A4
: 
Easy way that some may call cheap reg 1.15 with blades
A5
: 
Umm, thats one of the easiest matches in the game, I took em out with dual kiku but if you want an easy match use kojima, and even easier use grenade cannons and tank legs so you can hold more grenades.
A6
: 
Just beat it after a few attempts. Fast, 40000AP, VKojima high damage missiles for both back weapons, missile arms, high volume missile extensions, and a lot of luck (took out the last AC with my final payload of arm missiles:)
A7
: 
Kojima cannons, hide behind the walls and charge the cannons come out, and take them out one by one. But make sure your in close to take them out in one shot

This is quite possibly the most difficult battle you will ever face in a video game... Everything is slanted against you. but maybe with a bullet and a prayer you will pull it off.
First, assemble a NEXT that is as lightweight as possible with Max tuning on both maneuverability and energy weapon power. Using the Kojima cannon arms and two Gatling gun backs, max out on the powerful jump jets and so forth, you wont need to worry about energy consumption if you change the rules to 1.15 .
Enter the arena and immediately start charging your Kojima arms, you will soon fire them at an enemy that wont fire back. go to the back of the fort on the wall where you expect the four enemy nexts to fly in and await their arrival while you charge. start to hover approximately 30 feet off of the wall and wait for the third next from the left to close the distance. time your shot so that he is within 50 feet of you and you will kill him instantly, leaving only three to contend with.
After this, start to charge again while dropping on the outside of the wall, sometimes one will follow, if he does, eliminate him with a well placed kojima blast to the head. it helps to target if you are shooting your gatling gun while you shoot the cannon, because while the gatling gun is engaged your FCS will automatically track him.
Once his Next becomes the next home for coral at the bottom of the sea, make your way over to the split in the walls. charge your kojima, and wait a second while you judge your avenue of approach. Kick the tires and light the fires with your OB and shoot a few shots at one of the two remaining enemies, one or both will soon follow. keep flying untill you reach the end of the map, but don't go over. stop and turn around, and you will see one of them jetting towards you, making for an easy shot when he gets within range. The last Next will be your hardest, because if you did EVERYTHING right, you only have two charges left for your kojima, but you should have plenty of chain gun ammo left. you can repeat the OB technique, or you can stand and fight by jetting everywhere and holding down the machine gun button.... if you are lucky you will win the day and you will have earned your next achievement of another ending completed. it took me over 30 hours to figure this out. I hope it saves you time! )
