This is one of the assignments unlocked by completing the Project Firewalker: Rosalie Lost assignment.
On the galaxy map this it called Project Firewalker: Artifact Collection
Acquisition
This mission is acquired after the mission on Zeona. A new entry in the journal indicates Shepard should head to Corang (Verr system, Hawking Eta cluster) to start the assignment. Scanning the planet reveals an anomaly, returning no signal.
These mission notes are displayed after scanning the planet:
“Scans have found locations matching the descriptions of Dr. Cayce's survey sites. Exploring the sites could reveal valuable mission data. Warning: Geth presence detected on planet's surface. Use extreme caution.”
Walkthrough
When the Normandy drops of the Hammerhead, a Geth Colossus is shown activating and standing up. There are five sites on this planet you must scan to acquire the information you need.
Site 1
Immediately after you land there is a squad of Geth Troopers up ahead. Use the Hammerhead’s main gun to eliminate them. If you hear a warning siren then the Hammerhead’s shields are down and eventually the vehicle will catch on fire just like the Mako when it took heavy hull damage. Just move out of the firing area, just like when you are on foot and wait until the siren stops. Then head back in.
When you finally eliminate the troopers, move up to where the first location is. Guarding this site is a Colossus along with three Geth Troopers. However a Geth Dropship drops them off as you approach. The Colossus here is without health so batter down its shields then destroy its armor to eliminate the unit. Because this site is raised up from the ground, use the jets and keep moving to eliminate all the geth in the area. Remember to retreat if your shields fail. Once they are down scan the site and move on.
Site 2
Head around the corner and eventually you will see two Geth Troopers in the distance, shorten their life expediencies and move up. Be careful as you approach the cliff because that isn’t funny colored water, its acid that will destroy the Hammerhead instantly. Get onto one of the rock islands and prepare for another gun duel. On one of the left islands is a site that holds 1250 platinum, grab it because you are still out of range.
If you stay near the site you have a change of picking off the defenders without ever being shot at, much. A Colossus, a Geth Destroyer, and two Geth Trooper defend this site so it’s about the same as the last one. Use any tactics, preferably one at range to eliminate the geth. Once they are down, grab the research. It is not recommended you try to ram the geth, the Hammerhead is more damage prone than the Mako. If you go to the island to the right of the one with the ramp, the Colossus will not shoot at you and you can use the jets to take it down.
Site 3
One you have the research from the third site, use the jets to get over to the island and then up to the metal ship hulk. From here you have two options to get to site three, left up the ramps and through the tunnels; or right using the jets to get up to the platform. Either way you wind up at the same site.
As you approach the site another dropship flies overhead dropping a Colossus, two Destroyers, and two Troopers. A good tactic here is to use the ship hulk on the right path as a ramp to cross over the battlefield. Once on the other side you can shoot with ease because nothing will challenge you, because they can’t shoot at you. Once the geth are down, using any tactics you wish head to the artifact and collect it.
Site 4
To get to the next site you can either use the ramp as described above, or you can use some debris in the middle of the battlefield you just cleared. Either way you have to go up to continue. Once you are up, there is more acid and another ramp, guess what you have to avoid and how to do it. Once you make is across the acid pool, using the platforms as cover, the first platform on the left has a scan site for another 1250 platinum. When you get to the second platform. you come across two paths, one left and one right. This will determine where you start for the coming fight. If you like range, then go left, if you like to get up close and personal, not recommended in this vehicle, then go right.
Either way once you get close another dropship, curse them, drops another Colossus, a Destroyer, and a Geth Prime. Take them out any way you wish then collect the fourth artifact.
Site 5
Once you collect the artifact your best option is to go up the ship hulk that divided the previous battlefield. When you are about halfway up some friends fly up to meet you, three Geth Rocket Drones. They aren’t accurate at range, but then neither is the Hammerhead. Stay back to avoid the rockets and once they fall use the jets and boost to get to the elevated platform. When you get up there is a scan site to the right, its iridium not your objective but still grab it, 1250 platinum.
From here you should see the fifth site, and a dropship should be coming any moment now. Use the jets to get to the first platform then use the gun to take out the Colossus, two Primes, two and Destroyer from a distance. The Hammerhead is more accurate with large targets. You don’t even have to move to take out the Primes and Colossus. You may have to get up close and personal with the Destroyers however. Once they are down before grabbing the artifact there is a path to the right behind the site that leads to another site of Platinum. Then head back and end the mission.
