6.1.1. Geth Attack
Right after landing talk with David al Talaqani. He will send you to the colonists boss, Fai Dan (FER1-4). A moment later you'll be attacked by geths. They'll be coming through an entrance nearby, so it's good to crouch and shoot from behind the cover. Battle though the enemies and up the stairs to reach the Zhu's Hope colony. Geth will be disrupting your radar. The fastest way to eliminate the ones running on the walls is to use biotics.
Fai Dan (FER1-4) will ask you to help lighting the geths. Hide behind the stone block and eliminate the first wave of enemies. Then slowly proceed toward the tower (FER1-7). After repulsing the attack, come back to Fai Dan and inform him about it.
He'll tell you that information about what geths are seeking on Feros could be most probably found at ExoGeni facility, on the other side of the prothean skyway (6.2. Skyway). You can go there immediately or help the colonists first. Fai Dan will tell you about their problems.
6.1.2. Geth in the Tunnels
After completing mission 6.1.1. Geth Attack Fai Dan will ask you one more favor. He'd like someone to get rid of the geths in the tunnels and deactivate the transmitter, which is used to coordinate their actions.
Hint! Along with this assignment, you can also complete assignments 6.1.3, 6.1.4 and 6.1.5.
Go north and enter the tunnels (FER1-B). Continue toward the transmitter (FER2-1) eliminating geths along the way. You must kill krogan mercenaries at the place. Keep your distance and don't let them attack you in close combat.
After the fight, destroy the transmitter (FER2-1).
6.1.3. Water restoration
Macha Doyle (FER1-1) will ask you to restore the water supply to the Zhu's Hope. You need to venture down to the tunnels and open the valves to allow water to flow.
Hint 1! Along with this assignment, you can also complete assignments 6.1.2, 6.1.4 and 6.1.5.
Hint 2! This assignment could be also completed without talking with Doyle. You just need to open the valves and inform her about it then.
Go north and enter the tunnels (FER1-B). Proceed along the main passageway opening three valves one by one (FER2-2, FER2-3, FER2-4). After restoring the water supply, return to Doyle (FER1-1) and inform her about it.
6.1.4. Varren Meat
David Reynolds (FER1-3) has a problem. He needs to complete the colonists' diet in varren meat, but ruthless animal leader makes the hunt deadly dangerous. Your task is to kill it.
Hint 1! Along with this assignment, you can also complete assignments 6.1.2, 6.1.3 and 6.1.5.
Hint 2! This assignment could be also completed without talking with Reynolds. You just need to kill the varrens and inform him about it then.
Go north and enter the tunnels (FER1-B). Then, using the passage in western wall (FER2-B), head to the collapsed bridge (FER3). Varrens will attack you there. Killing them is easy unless you remember not to stop for long in one place. After eliminating the alpha animal, you just need to inform Reynolds (FER1-3) about it.
Hint! After killing warrens, it's good to take the power cell from the damaged vehicle (FER3-1). In other case, you'll need to come back for it to complete assignment 6.1.4.
6.1.5. Power Cells
May O'Connell (FER1-2) will ask you to find a new energy source.
Hint 1! Along with this assignment, you can also complete assignments 6.1.2, 6.1.3 and 6.1.4.
Hint 2! This assignment could be also completed without talking with O'Connell. You just need to take the cell and give it to her.
Go to the same place where you fought with the varrens (FER3).
Hint 3! If you didn't complete mission 6.1.4 earlier, you'll need to kill them now.
Take the power cell from the damaged vehicle (FER3-1)and give it to O'Connell.
6.1.6. Espionage Probe (Investigate Shipments)
Head inside the freighter at the Zhu's Hope colony and access the terminal (FER1-5). You will receive a message informing you of several supply shipments that have been diverted to the Voyager cluster. The case is worth investigating (126.96.36.199).
