So Raven, you have decided to test your metal (pun intended) and cut your teeth on attempting to S-Rank Armored Core 6. You have proven yourself by conquering all possible outcomes and you have reached the final hurdle. Here in this guide, your fellow pilot will show you how to achieve sweet victory in the skies of Rubicon 3.
My name is Ryan, but you can call me Twig. I’ve done countless tours across Rubicon 3 and I am currently sitting in the top ranks of the arena. You can count on me to get you through this.

Chapter 1: Illegal Entry Walkthrough
Ah yes, the start of it all. Do you remember, Raven? The very first trial by fire was overcome so long ago, in a bare-bones AC no less. Look at you now. You have acquired the reputation and firepower to bring even the corporations to their knees, but this is a new challenge. It’s time to prove that you have earned your name.
This mission is unique in that you will be provided with your AC. Welcome back to your very first machine. I hope you can adjust now that your fancy toys have been taken away. Your objectives remain the same, but there are a couple of extra conditions if you want to successfully achieve S-Rank.

First, time is of the essence. You will be judged on how quickly you accomplish the objectives.
Second, there are no do-overs. This means that if you die you had better go back to the starting line.

Strap in 621, and begin the sortie.
Begin by flying up to the hallway. At the end, use multi-target lock with your missiles on the 4 Guard Mechs below. They will die with one missile each.
Move on and take out the rest of the units here before going to the catapult.
Another rough landing, but there is more danger ahead. Destroy the 4 MTs and move to the edge of the cliff.
Begin by obtaining the license on the left side of the city by the massive downed spacecraft, and then move on to the one on the main road. The last one is on the rooftop surrounded by MTs and helicopters. Destroy them and scan in peace.
Now you may move to the vertical lift to go and meet your old friend, the AH12: HC Helicopter.
Start by standing on the nearest roof to where it flies in and land a few hits with your sword while peppering it with fire. As it moves around the battlefield, be sure to use cover to recover energy, and abuse your assault boost to close the gap for a couple of sword attacks. Keep up the pressure and you should shoot it down in no time.
Well? How did it go? Did you succeed? If not, fret not. Adaptation and persistence is the true key to victory. Triumph is sweeter after a trial.
