This quest can be completed solo; but is easier, and grants bonus rewards, as a group.
Acquiring Shield Frequency Code
Proceed to a camp, the surveillance droids nearby indicate the name of the camp. These names change every Phase 3. Within 100m of the camp there will be non-aggressive Patriots that can be killed to get a Remote Frequency Code.
This code has a 6 day lifespawn. Once acquired, return to Captain Sarguillo to turn the Remote Frequency Code into a camp specific shield generator remote.
You can additionally loot chips that, when decrypted by Captain Sarguillo, provide waypoints to camps. The next waypoint acquired will always correspond to the last frequency decrypted.
Assaulting a Camp
Once you have located the camp you have a shield generator remote for, the next step is to assault the camp. Upon using the remote, the turrets and gates become vulnerable and waves of 8-10 patriots start spawning and running in. To spawn the commander you must kill at least 5 of these defending patriots.
First things first though, there are two outer turrets, an outer gate, a single inner turret, and an inner gate that need to be cleared. The inner gate can be dealt with after getting 5 kills, the others will hinder your progress towards getting 5 kills.
The spawns despawn after a certain amount of time as a new spawn appears. For getting your 5 kills you can try to pull off 2 or 3 at a time to deal with, beware the turrets are strong and will shoot you if they can see you. Once you have 5 kills, the best bet to get into the base, after the gate is destroyed, is to time it to run in as a group is despawning before a new spawn arrives and avoid an impossible fight against a full spawn.
Once inside, radial the Rallymaster and capture. This starts an invisible 1 hour timer to escort the commander back to the Village. Beware the base guards will still be spawning so you will either need to time leaving or just burst run out. Additionally, packs of 4 patriots will spawn repeatedly while you escort the Rallymaster back.
This quest involves surveying for a series of resources at a 50%+ concentration. You do not need to sample, just survey with the tool at a spot with a high enough concentration. You can go to other planets and still get credit.
In a random order, the following has to be surveyed:
7 random crates of either Endrine, Rudic, Ostrine, Ardanium II, or Wind Crystal
