WALKTHROUGH - Mission 05 - Mountain Route 2

Mission Objectives:

"Proceed across the second mountain route. When you reach the tunnel, pass through it to reach the other side of the mountains."

UP THE SECOND MOUNTAIN...

Move forward and start blasting the Spider Akrid hive up on the mountain to keep their numbers small then kill off some of the remaining Spiders to thin them out a bit. A giant moth will eventually fly by the area and create a wind gust. This wind gust will knock you and the Spiders down the side of the mountain if you don't take cover in an alcove or room along the mountainside. Whether it is a room or two pieces of debris, you must take cover somewhere or the gust will knock you back down to the bottom. Keep in mind that avalanches will occur frequently while moving up the side of the mountain, so you will need to quickly take shelter in one of the rooms up above - roll or jump quickly through the doorway.

 

Go ahead and start to grapple and climb up the mountain on the left side. Grapple to the metal platform closest to the ground then pull yourself up and look off to the right to see a concrete ledge. Grapple onto the concrete ledge then seek cover in the alcove to the left as the avalanche starts and grab the MACHINE GUN inside. Run back outside and activate the DATA POST (1/3) on the concrete ledge. Grapple to the next small concrete ledge then blast the hive that the Spiders are spawning out of. There will be an avalanche on the side with the hive, so don't race over to the sheltered area beyond it just yet. When the avalanche clears, run into the alcove to the side and pick up the HAND GRENADES and the ENERGY GUN. Run back outside when the moth leaves and walk back over to the left side (where the hive on the wall is) and grapple up to the ledge up above. Run directly into the room in front of you since some boulders will start to roll down the side of the mountain. The room will have a Spider Akrid hive in the portion that you must enter from so blast the barrels in the back and the hive to quickly get rid of it. Grab the MACHINE GUN in the back and run back out when the moth passes by.

 

Look to the right after you exit from the room and grapple to the small ledge to the side with a MACHINE GUN on it. I wouldn't recommend trying to get that machine gun since this ledge is very narrow. When you grapple, hold the left analog toward the ledge past it to land on it instead. Boulders will fall from the side of the mountain so be prepared to dodge them. Throw a grenade into the room ahead since it will be covered with Akrid and explosive barrels. Duck into the room when the moth flies by and grab the GUN GRENADES and the MACHINE GUN inside. Walk back out onto the ledge when the coast is clear and blast the hive on the right mountain wall. Pick up the LASER RIFLE and drop the energy gun, then grapple up to the next ledge above. The laser rifle is the best weapon to use if you want to defeat the Giant Mouth - read below. You'll find some more GUM GRENADES and another MACHINE GUN inside the room on the ledge. You need to grapple to the next ledge up above the current one. It's a little hard to get the camera adjusted just right, but you should be able to walk outside of the room and turn right while looking up for a perfect angle. Walk along the snowy ledge and move very fast over to the path on the far side so you can take cover against the mountain wall to avoid the moth when it swoops by again. Run into the cave.

Defeating the Giant Moth

 

Fighting the Giant Moth is optional, but you will gain an Achievement for killing it. Grab the laser rifle while climbing up the side of the mountain then get in between the mountain walls on the snowy ledge before running into the cave in the back and wait for the moth. The moth will not be able to hit you with the gusts of wind from its wings as long as you stay in this area. When it flies overhead, shoot the bottom part of its body. It should fall after a few hits depending on the difficulty. The moth will shower the area with T-ENG then eventually crash into the side of the mountain when it dies. The Achievement will be earned after this level is finished.

INSIDE THE CAVE...

Still got that laser rifle? Good. Walk further into the cave and grab the MACHINE GUN off to the side then drop the laser rifle for a bit. Thin out the Trilid Akrid in the distance just a bit so they don't constantly dive toward you. A Wasp Akrid will appear among the Trilid. This Akrid will buzz around then stand still to shoot a projectile at you. Pick up the laser gun and charge while waiting for him to stand still then blast him in his heat source on his lower body when he does. It should only take about two hits. If it moves around too much, shoot one set of its wings on either side. This will cause him to fall to the ground on his back exposing his heat source. Wasp Akrid are basically dead once they can no longer fly - keep this in mind when they start appearing in groups. Move down the left side and activate the DATA POST (2/3). There's an ENERGY GUN further down the left side. Your destination is up on the right side, but you can explore a bit down below by jumping down the ledges on the left side. This will help you to gain some more thermal energy and find some HAND GRENADES, 2 SHOTGUNS, a GATLING GUN, a VS SHOTGUN, and some GUM GRENADES. There is also a GTF-11 Vital Suit at the bottom. If you still have that laser gun from outside then equip it to the VS suit along with a VS shotgun for some ultimate firepower!

 

While moving up the right side, two Spore Akrid will surface from the ground. These Akrid will shoot spores from their top circular portion that will rain down upon the area around them. Shoot them in their top bud portion to kill them quickly. Get in the standard GTT-01 Vital Suit if you didn't get the better VS from below. Try not to shoot the boulders while moving along the side or the rocks will roll down the ledges and damage your VS. You'll come across two MACHINE GUNS on your way around the ledge. More Spore Akrid will appear on the other side. Shoot the Trilid hive up above the boulders but don't shoot the boulders or they will only damage your VS as they roll toward you. Keep moving around the side of the ledge and grab the MACHINE GUN and GATLING GUN up ahead. Eventually some more Wasp Akrid will fly up to you and attack. Some more Spore Akrid will burst up from the ground further ahead. Blast the Wasps with the laser gun or gatling gun. You can also blast the red stalactites for some extra T-ENG. Even more Spore Akrid will appear further up the ledge. Grab the VS SHOTGUN along the way.

 

Blast the Trilids as they dart out of the tunnel to the side then have a shot ready for the Wasp Akrid that will attack from the entrance. Walk into the tunnel and shoot the stalactites and eggs for a major T-ENG boost. Try not to shoot the boulder on the way up the steep part of the tunnel. Hop into the GTF-11 Vital Suit inside of the tunnel and equip it with the laser rifle or VS shotgun. Charge a laser blast and shoot the Wasp Akrid perched on the ledge in the distance to kill him. Activate the DATA POST (3/3) right outside the tunnel then jump and hover with the VS over to the ledge on the right side. Grab the GATLING GUN while moving into the tunnel if you need it then drop through the next few holes in the back of the tunnel.

DEEPER INTO THE CAVE...

 

You'll enter a segment of the cave with a frozen column in the middle of the room. There's a standard GTT-01 VS inside over to the right. Enter the tunnel to the right to find a room with tons of eggs and some HAND GRENADES, an ENERGY GUN, and a GATLING GUN. You'll need to pick up the gatling gun and bring it toward the middle of the room to equip it to your VS. Enter the tunnel across from the current tunnel to find a GTB-22 VS suit along with a MACHINE GUN and another GATLING GUN. I would recommend entering the GTB-22 model so you can move about more freely - this will help for the boss fight to come. Equip it with a laser gun and a gatling gun. Go back into the area with the frozen column and blast the Akrid seal on the entrance of the tunnel beside the standard VS then fall down the hole inside.


Boss - Giant Chryatis

 

This boss has tons of weak spots on him making this fight not as bad as the last, but still challenging. The main thing to keep in mind during this battle is that the closer you stand to him, the less likely he is to hit you. Like the last battle, you really need to know the boss' moves and how to avoid them to win:

1) The Chryatis will lean his right or left arm back and swing it toward you horizontally.

How to avoid: Jump right before he swings his arm.

2) The Chryatis will lean his right or left arm back and swing it toward you vertically. He will sometimes do this three times in a row and will usually get his claw stuck in the ground on the third time allowing you to blast him.

How to avoid: Move/Dash to the side. Remember that he will always delay the third strike to throw off your timing.

3) The Chryatis will lean his head back and breathe a trail of ice in front of him.

How to avoid: Move/Dash to the side.

4) The Chryatis will bang his claws against the ceiling and make boulders fall along the outer area of the room.

How to avoid: Move/Dash to the side. You can also run directly toward him since the boulders will only fall in the outer area.

Most of his attacks can be avoided easily, but some of them require a bit of extra maneuvering. The main focus of the battle is to stay in the VS for as long as possible. There is an extra GTF-11 Vital Suit, a GTB-22 Vital Suit, and plenty of ammo lying around, so you need to make good use of them. Stay right next to him if he ever destroys your VS and find another VS around the area.

As mentioned above, there are several heat sources on the Chryatis and hitting these heat sources enough will cause him to fall over on his stomach and lift his head up. His glowing eye is the major source for damaging him. To successfully hit him, shoot either the top part of both of his arms or the glowing section of the appendages on the sides of his body. I would recommend standing right next to him and moving to either of the sides while shooting one set of appendages with a gatling gun. This way, you'll avoid most of his attacks while you work on one set. The appendages are very weak and will fall to only a few gatling gun shots. Once one of his arms has been shot off or all the appendages on one side have been shot off, he will fall flat on his face and lift up his head, exposing his glowing eye. Charge a shot with the laser gun or fire a rocket and shoot him directly in the eye to really damage him and spread several pieces of T-ENG from his head. Also, one grenade blast will severely damage the eye more than any other weapon if you hit it just right. He will fall down again and lift up his head once again. Fill him full of laser blasts or other weapon fire while he is down until he raises up again. He will regenerate whatever part of his body that you shot off and go back to attacking normally. It is very important that you injure him badly enough to where he drops T-ENG since you will need that T-ENG to shoot the laser gun and damage him badly. There are also three stalactites hanging from the ceiling directly over him that can be shot down and will damage him if he is underneath that particular stalactite. I would suggest saving them for the last few final hits. Toward the end of the battle he will start to combine moves aggressively and start a whole new move:

5) The Chryatis will fire out an ice ray horizontally with his mouth.

How to avoid: It is best to jump and hover in the air when he does this. It can be escaped by moving toward him also but you must remain close.

Keep shooting him with the gatling gun in his heat sources then blast him with a big weapon such as the laser gun, rocket launcher, or grenade launcher whenever he falls. The rate of shots is much faster with the laser gun allowing some incredible damage when he falls.

Boss - Giant Chryatis (EXTREME MODE)

Bring a Vital Suit with you, preferably the GTB-22 suit. Equip it with a gatling gun and a rocket launcher. The most important aspect of this fight is that you stay near him and circle him while blasting the appendages on his sides (with a gatling gun) to make him lean over. Once he leans over, fire a rocket into his eye then fire another when he falls to the ground. He will be coughing up a bunch of thermal energy with each major hit that you deal to him. The only hard part is when you run out of ammo and are forced to venture away from him to find another weapon. He is a total monster at long distance, so make sure that you get back up to him quickly. You may want to cripple him by shooting him in the eye once so his head falls to the ground then go for another weapon while he recovers. There is another Vital Suit in the room, but that doesn't mean you shouldn't bring one. There is a grenade launcher in the room if you can find it. Don't forget to shoot the stalactites above him for some possible damage. Constantly stomp on the Akrid eggs around him to gain some extra thermal energy. Never leave his side unless you are forced to.
