Lost Planet 3

To obtain this achievement you will need to purchase all of the upgrades for both your Rig and for your weapons.

There are three shops involved in this task. One weapon shop at your main base, one Rig shop at the main base, and a weapons shop at the Camp of the Forgotten.

Your currency is your T-ENG, unless buying parts for the rig, in which case you will need Specialized Components. These can be found hidden around on the ground in areas OR purchased for 2000 T-ENG each from the weapons vendor in the main base.

Below are the items and prices of what you will need -

Hunting Knight - 10
Shotgun - 1500
Assault Rifle - 2500

Extra ammo and grenade packs are not required. I don't believe extra weapons outside those bought in the shop are required either, like some that you find on missions (like the Halberd gun you find in the security installation after you have the magnetic hook...)

Lost Planet 3 Specialized Component Locations

After taking Rig outside the first time, take a left to the small walkway and jump out of Rig. Run down the pathway to the metal door, to the left
of door is a stack of crates with ice on the bottom. Shoot the ice and pick up the component.

After returning to the main base once a emperor storm is coming, you eventually can go back outside. Your objective will be to grapple down a cliff to
rescue an escape with people. After that you will crawl through a cave and fight some enemies that shoot explosives. Right next to second crate
you can take cover is another patch of ice with the component inside it.

From the same location as the previous component, continue further along the path grappling as you go. After fight a good swarm of enemies you will grapple
up a low ledge above you. Directly in front of you will be another crate with ice, and the component is inside.

During the mission "My first T-Energy Post" you will come to Hanneman's Basin and will be walking down a stretch of ice during a storm. If you open your
map you can see a small outcropping to the north that has this component laying on the ground next to some thermal energy canisters.

When you finish the mission "My first T-Energy Post" you will be transported back to the main base. Once you can explore again, track the mission
"Visit Kovac's Lab" and head to the elevator it leads you to when you press up on the dpad. Once you get off the elevator, the component is
on the ground in front of you to the right a little.

Once you are ready, head outside back to White Canyon Junction to where we rescued the french guy. Head to the north of where the french guy was hiding
and there is a path there that can be grappled up to. There are two components here at the back.

While you are heading to the com-relay for the main mission, you will pass through Bailey's Crossing. In the center is a platform with drill next to it.
On the south side is a hole in the ice that can be grappled down. There are two components in some ice that can be broken at the bottom.

While still in Bailey's Crossing, head to the northeast and there is a ledge that can be grappled up to. Walk under the ice pillar and in a breakable
ice ahead is another component.

In the next area, Bishop's Wake, after dealing with the enemies here head to the far right on the map and there is a small area to grapple down. At the
far end here is a component that is somewhat buried in the snow.

From the previous component, hop back in the rig and turn around heading north. After maybe twenty steps is an ice column in the ground and there is a
breakable ice pack at the bottom with another component.

From the previous component, look back toward the grapple point to the south, there is another chunk of ice that can be broken in the southest corner
that has this component. Directly to the left of where the grapple point is to drop down.

After climbing up Shackleton's Peak a short way there will be a tower that you can explore. This component is near the bottom, just up some stairs.

After your Rig is docked on the tram platform, look at the platform the Rig is docked and there is a breakable ice to the left of the Rig with a component.

While hiking up Shakelton's Peak you will be turning on sub stations for power. After the fourth sub station eventually come to an area filled circular
tubes laying in the snow while fighting waves of enemies. Wrap around the path and this component is to the left before grappling up the cliff.

Once you make it to the top of Shackleton's Peak and after fighting the boss, you will call your Rig up to the top as well. This component is to the left
of the Rig in some ice under some blue energy generators.

After you make it back down to the bottom of Shackleton's Peak, you can do a sidequest to talk with a Doctor. Her quest will lead you to a small cave
right down the path from her location. Once inside the cave this component is on the ground straight ahead next to some eggs on the left. (May not
be there until you come back here after advancing the main quest ahead to the next step.)

This component can be found after progressing the story to Marshall's Gorge directly after the boss fight there. Once you plant your T-eng post a building
will be ahead of you. On the ground to the left before entering is a yellow piece of machinery. This component is on the ground by the yellow thing.

When you are exploring the abandoned generator area and have made your way to the second area after a loading screen, continue forward through the door that is
struggling to close. When you duck under it, this component is straight ahead in a pile of snow.

For this one you will be inside the power plant during the mission "Escape". After you have opened a door and fallen off a ledge you will be in an area
surrounded by ice. You will need to walk across a beam and then grapple above you and then follow a path that has you ducking through some type of
wall with piping in it. After another grapple, beam walk, and a final grapple you will be in a room with stairs going up and down. This component
is on a crate at the end of the stairs going down.

Very soon after the previous component, you will have to fight off a wave of enemies in a big room with tables and crates. After the enemies are dead, head
to the back left towards the dead humans and this component is on the table.

Continue on with the main mission until you make it back to you're RIG and need to bring it inside. While looking at your RIG, turn left and look up at the
ceiling. There is two grapple points up at the top of the wall. The second point has a component sitting on a console.

Continue on with the main quest for quite a while. After events play out and you are in Pickett's Folly back with your RIG you will want walk your RIG over
to the middle of Pickett's Folly and use the winch to grapple the northern island where the main quest "Retrieve the Medicine" takes place. After
working your way through the enemies you will grapple up to a metal platform that has two components, one to the left and one straight ahead.

While you are in the security facility during the main quest "Access Base Armory" you will come to large circular room with a turret at the center. Once
you clear the initial wave of enemies and turn on the switch, the armory will unlock and spawn a large wave of enemies. Once they are dead, head
down the stairs into the armory with two more turrets. To the right on some shelves is this component.

*****The following components were extra for me and didn't have anything to buy*****

After you are back at the Camp of the Forgotten you will get the magnet upgrade for your grappling hook. Head toward the quest objective and grapple to the top of the greenhouse roof and this component will be up there.

Once you progress through the main quest a bit you will end up needing to head to Bishop's Wake for some drilling. Once the drilling is finished, you will be facing a grapple point for your RIG that requires the "Extended Winch" upgrade. Grapple to the point and break some ice for this component.

Back at the main base Coronis, head outside the big doors and take a left. There is a winch grapple point above the metal door that you can grab if you stand close to the anchor point holding the space ship. Grapple to the point, and then grapple up to the cliff there and there is a component in ice. This one may also require the "Extended Winch" upgrade, but I found this one after I already had it.
