10.1 – ENTRANCE TO VAULT
Walk down the path, and head towards the construction equipment. As soon as you clear the train car, a cutscene will begin. In the cutscene, Hayden meets with the ‘A.D.’ face to face, and gives him a piece of his mind.
After you regain control, kill the Hazmat troops. Start with the ones who are getting up, they are easier to get rid of. Once all the troopers are dead, walk into the large cliff side opening that leads into the Vault. Follow the train tracks inside. After entering the large room, turn right. Then locate the ladder that leads up to the Vault door control room. At the top of the ladder, turn right and enter the small room. Press the button that is to the right to open the large door. Climb back down the ladder and go through the open door.
10.2 – INSIDE THE VAULT
Walk up onto the staircase to the left and follow the train tracks down. You will come across hordes of Stingers and Chroma. Battle through the hordes of enemies to reach the elevator on the left side, on the other side of the barrier. Once you reach the elevator, use the Action button on the control panel to the left of the elevator. An alarm will sound, signaling that the elevator is on its way up, which attracts more enemies. Defeat them, or survive long enough for the elevator to arrive. Step inside and it will descend.
When the elevator stops, exit and run to the opening to the right side of the room. Follow the path to the back of the room, and push the button to open a door. Return to the elevator room and go down the stairs on the left. When you passe through the doorway, there is another cutscene. Continue forward down the path, into a large room with two train tunnels. Take the left tunnel.
10.3 – MEZNER
Walk along the train tracks until you reach a large dock area. A cutscene will play, filling you in on the story.
Mezner will summon three huge tentacle monsters. Hit the blue spots to expose their weak points, which is inside their mouths. Use electricity (throw the Glaive at the transformer to the right of the fight area on the green structure, or the large transmitter above Mezer’s ?throne?) on their weak point (it looks like an eye). If you get too close, the tentacles will attempt to crush you, and they also spit acid and throw rocks. If you throw the Glaive at one of the tentacles and miss the weak spot or its kill point, the tentacle will attempt to grab you. If it grabs you and if he is grabbed, it is instant death.
So the first stage of the Mezner fight is pretty straight forward. Dodge the tentacle’s attacks, counter attack with the electrified Glaive until all three tentacles are dead. Now Mezner will show himself. Mezner will mentally attack Hayden, and if Hayden does not hit him with a Power Throw, Mezner will kill him. So Power throw away.
After Mezner has a taste of the Glaive, he will summon up two more tentacles. Also joining the fun are two Howlers. The Howlers will come out of the ground off to the left and right near the green support structures. The tentacles also have a new attack as well. Now they will open their mouths and ?kiss? the ground. A spike will move in a straight line, popping in and out of the ground as it attempts to hit attack Hayden from below. Just like the other tentacles, pop the blue spots to make their mouths open up, then finish them with the electricity.
Once again, Mezner will come out of his shell and try to attack Hayden mentally again. Power Throw the Glaive at him to shut him up. Now, Mezner is mad. He summons up five tentacles (three in the middle, and one on each side of Hayden). This round, the tentacles have two new attacks. They will spit a fireball at Hayden, as well as an upgraded ?kiss? attack. The spike will come up out of the ground and attempt to choke Hayden down to the ground, where the spike will then stab right through him. Complete the mini game successfully to avoid this grisly death.
Just as the rounds before, destroy the blue spots on the tentacles, or win the mini game and slice its tongue off, to make them open up. Kill all five tentacles, and Mezner will attempt to kill Hayden mentally. This time though, it is all or nothing. Power Throw the at Mezner to activate the end cinematic.
