Armored Core 5 Walkthrough Part 15: Chapter 00 Part 3

After bringing the Rokh down, boost down the highway and into the tunnel ahead. Keep boosting down the straightwaway until you reach a hole in the ground. Drop down into the hole. You will land in a dilapidated train tunnel. Keep boosting down the central path to find another hole in the back of the train tunnel. Drop down another level. You will now be in a small, cylindrical tunnel. Boost down the linear path ahead. You will pop out of the end of the pipe and into a deep sewage system of sorts. You will have to reach the continuation of the small, circular path on the upper side of the opposite wall.

Boost over to the opposite wall and boost jump up the sheer face of the wall to reach another cylindrical path. This will lead you to another drop just like the last one. Again, boost jump up the wall to enter a third cylindrical linear path. This will deposit you in yet another deep sewage room. Boost up the spiraling path to the right to reach the exit. Follow  this small path. It will lead you to the final sewage room. Jump across to the large, brightly lit exit on the other side. This will trigger a cutscene.

You will now come face to face with the enemy leader, Vendetta, again. It looks as if battle is inevitable. Vendetta will augment its arm units, making for a very fearsome looking foe, even though it has clearly been heavily damaged from your last battle. Before you can attack, though, reinforcements will show up. A heavily armored AC will burst out from nowhere and knock Vendetta through one of the columns holding the ceiling up. Your savior will be none other than the Chief, who will chastise you for taking your time in reaching Vendetta for a second time. He will also congratulate you on mopping up the mess in the city. As you leave with the Chief and the head of the City Police, Vendetta will receive an incoming transmission. Another rebel general will confirm that she was able to escape with a few rebel stragglers. When the mysterious voice receives no response, she will confirm her identity as Vendetta’s daughter. Sadly, Vendetta will remain unresponsive. Following this mission, you will learn that the government was largely successful in destroying the rebels forces. War still rages on, though, as the defeat of the rebels wasn’t enough to deter others from attempting similar things.
