Saren sent the geth to Feros to destroy an alien life form known as the Thorian. Why Saren wants this parasitic plant creature destroyed is still unclear, but it has evidently taken control of most of the colonists back at Zhu's Hope.
This mission is acquired after the destruction of the Geth Dropship and after a radio communication from Joker. The mission is the continuation of the Feros: Geth Attack mission.
ExoGeni Headquarters EditGeth Dropship to the building. The claw is sheared through and the cutscene switches to the exterior of the skyscraper where the dropship is starting to fall. The other two claws fail and the ship drops into the rubble that covers the surface of Feros. The cutscene jumps again to where the forcefield that was and the blue field drops while one of your squadmates points out that it should be down now.
The second it falls, Joker comes over the comm and apparently is desperate to contact the Commander. Reply and Joker will tell you that the colonists have gone crazy and are clawing at the Normandy’s hull. You can respond but no matter the action the crew will stay in the ship to prevent the crazed colonists from getting in. He also says that there are a lot of geth heading Shepard’s way, so be prepared. Head back up the stairs, check the area again for crates and back to the main room where the forcefield was. Meeting you there is Lizbeth Baynham and now you can confront her with the information you retrieved from the ExoGeni VI.
She confesses to knowing and she says the reason she stayed behind was to send a distress call but got cut off before the transmission was sent, so she hid. You can interrogate her further and she gives up all the details of the Thorian project and why she was suspended. She was apparently very vocal in expressing her displeasure with the project and what it was doing. When you are done, she wants to come back with you to try and help.
When you regain control Lizbeth will be gone but apparently gets into the Mako when you do. When you turn to leave don’t think that your trip back will be easy, more geth have positioned themselves along the skyway and are just looking to stop the squad from getting back.
Head Back Toward Zhu’s Hope Edit
When you exit the ExoGeni garage, on the other side are two Geth Armatures and two Geth Juggernauts outside that are just waiting for you to come out. There are also some Geth Rocket Troopers and Geth Shock Troopers as well, but they aren’t the biggest threat. Deal with them, using the garage door if necessary to avoid their fire (Tip: their shots will always target the very front of the Mako at the time they fire, so you can avoid quite a lot of damage by keeping the front of the Mako hidden behind the bulkhead). Then roll down the skyway and back to the ExoGeni bunker.
As you get closer you hear another radio transmission from Juliana Baynham asking for help, Ethan Jeong is then heard telling her to get away from the radio. Lizbeth asks about it then you hear Juliana again using a general distress call and then is cut off. When you get near the bunker a cutscene plays where Lizbeth asks for the Mako to be stopped and she exits and head down the ramp, exit the Mako and follow her. If you were on foot, you are put back in the Mako and the Mako is relocated here for the cutscene.
ExoGeni Bunker Edit
You have a few options from here, if you don’t have the necessary Charm/Intimidate points, 10 Intimidate or 12 Charm, then you can’t reason with Jeong and Shepard shoots him when Jeong draws his pistol. If you have the necessary options then you can convince Jeong that saving the colony is worth ExoGeni’s time and money, either by appealing to the “against all odds” approach paragon, or by threatening him with Shepard’s Spectre status renegade. If you choose to use the options then Jeong will agree to support and expand the colony with ExoGeni resources, and you bank a lot of morality points and can significantly impact the fate of the Feros colony. Either way Juliana will ask to speak with you before you leave for Zhu’s Hope.
If you managed to talk Jeong down then Juliana thanks you; if you shot him then she sees it as a bad sign because ExoGeni may pull out. She will ask you to spare as many colonists as possible and after some talking she speculates that using a modified nerve gas might be the best thing to help take down the colonists because of their weakened immune systems. The nerve gas isn’t weapons grade but is enough to take down the colonists without harming them; the only other safe option is to melee them. Or you can do neither and just kill everyone. Either way, you will want the Anti Thorian Gas for your grenades for the final battle, so equip it into your grenades now.
Back on the Road Edit
When you are ready head back up to the Mako and head out of the Weigh Station and back on the last part of the skyway to Zhu’s Hope. If it wasn’t already obvious the geth are mounting a final defense to prevent Shepard from getting back. Just beyond the door are more Rocket Troopers, Juggernauts, Armatures, and Shock Troopers. Deal with them either on foot or from the Mako. The Mako is quite sufficient by itself if you are good at rocking back and forth to avoid fire and don't mind the reduced XP. If you are able to use a sniper rifle, then positioning yourself behind the pile of dirt in the middle of the road, you might be able to take them all down without them being able to hit you. Your squad members should stay out of the line of fire as well, because their helpfulness when doing this, will be questionable. When the geth are down move up and when you reach the part where the skyway broke and a large section goes down to the lower level there are two final Armatures that block your path to Zhu’s Hope, so make sure to take out this final road block. Then move along the skyway until you reach the garage door to Zhu’s Hope.
Assault on Zhu’s Hope Edit
When you get close enough to the door, Shepard and the squad will exit the Mako and observe a creature on the ground folded up like the geth in storage mode. When the squad gets close to it, it wakes up, stands up and attacks. You regain control shortly so shoot the thing dead. When it falls your squadmates ask what it was and you have two options that do affect your squad’s actions. If you choose the “Don’t shoot the colonists” dialogue option, then your squadmates will only fire on the creepers and not the colonists; the other option will cause your squadmates will shoot at everything including the colonists. A display in the lower right hand corner will let you know how many colonists are still alive, starting at 16; the number of colonists you kill will have an impact on the colony's ultimate fate. It is recommended you save before you open the door.
When you regain control open the garage door, and for safest results quickly jump back in the Mako. You will come under attack from a large number of Thorian Creepers, but the Mako's guns, especially the cannon, will make quick work of this first batch with no danger to you.
Be careful not to target the colonists behind the barricades on the upper level inside the garage if you're trying to save them. For preserving exp gain, you can always use the time-honored tactic of periodically using the Mako's guns to shorten the creepers' lives before hopping off the vehicle to finish them on foot. For more in-depth tactics on killing the creatures, see here.
When you've dealt with the first wave of creepers, equip the Anti-Thorian Gas to your grenades if you haven't already. More creepers are ahead, prepare accordingly. If you're playing paragon, fling a grenade at the colonists. They're usually clumped in groups; aim for the middle guy to increase your chance of taking down all four in one shot. If you're playing renegade you can just shoot the colonists and save the grenades for when you're under pressure from multiple Thorian Creepers. Lots of morality points are to be had in this part of the mission, and what you get depends on the number of colonists saved or killed.
If you run out of gas grenades, don't worry; meleeing the colonists knocks them out instead of killing them. Remember that storming into an enemy causes you to make a melee attack; if you're having trouble pulling off melee attacks with your attack button without accidentally shooting the colonists, charging headlong into them is a good alternative strategy.
When the creepers are biodegrading and the colonists are either dead or safely incapacitated, then head into the elevator.
Note: Once you use it, the elevator will be disabled, so this is your last chance to return towards ExoGeni Headquarters to deal with anything you left undone (e.g. locked containers or electronics).
The Colonists Fight Back Edit
When you reach the bottom of the stairs there are the barriers from before, about 5 to 7 creepers, and more colonists. Use a grenade to incapacitate the colonists or just shoot everything, your choice. When you have dealt with the enemies at the gates, move up and around, the freighter will be locked so you can’t go through it, so head right and up to the elevated catwalk. When you get up there is a box on the ground that will give you five more grenades to use wisely; if you're fewer than give grenades from your carrying capacity then be sure to expend some grenades before opening the box so that you get the maximum benefit.
Insanity Tip: There will be LOTS of creepers in the upcoming section, so if you can make it through this level with a few grenades left over -- easy to do if you're not saving the colonists, a bit harder otherwise -- then you will be very glad you have them later.
There are also some creepers on the catwalk so watch your step. When you get to the other side, there are more barriers, creepers, and the last of the colonists. Once the creepers wake up, retreat from the area with the colonists so you can deal with the creepers individually. Once all the creepers are down return and you will be able to precisely grenade or melee the colonists. When they are all down one way or the other, one of your squadmates will ask if Shepard can work the crane to get access to the Thorian. Just walk over to the crane controls and activate them.
When you do, a section of the freighter will rise exposing a stairwell leading into the underworks of the colony. Just as Shepard is about to step down Fai Dan comes around and says that the Thorian wants him to kill Shepard, but while the pain is apparently immense, he still manages to resist and shoot himself in the head. Head down the stairs and you are treated to a cutscene where Shepard and the squad descend into the Thorian’s lair.
The Thorian's Lair Edit
When you regain control you get your reward from either killing or gassing the colonists, you get two points for each colonist either killed or saved. Head down the stairs and just keep going because there will be no enemies. Before you reach the bottom, however, save the game. When you reach the bottom a cutscene plays. One of the squadmates starts talking about finding a central core, and the team is soon confronted with the enormity of the Thorian. The large creature notices the team and expels a green-skinned asari clone.
The Asari Clone starts speaking to you, and explains that the Thorian was attacked by Saren to prevent Shepard from gaining access to the knowledge to understand the beacon’s vision. The Thorian absorbed the essence of the Protheans and gave the knowledge to Saren in exchange for her and an understanding that the Thorian would be left alone. Saren broke the agreement and attacked, however, so the Thorian does not want to talk to any 'meat bags' such as the team. The conversation ends abruptly and you regain control.
The Thorian's Minions EditThrow to throw the asari off and into the abyss below the Thorian - safe disposal for an extremely tough foe. Then turn to the Thorian creepers that are scattered around and use powers, gunfire, grenades, and well anything else to take them down - just don’t let them get close. When they are down, one of your squadmates notices something in the next room, so go and investigate. In the room is a large ball of organic material that is attached to the wall, shoot it and the node will eventually be destroyed. The second it is destroyed, the Thorian groans, or screams, and your squadmates will comment that that hurt it and now you have to hunt down the rest of the nodes. Heading upstairs you are also soon treated to another cutscene where the Thorian produces yet another clone.
Beating the Thorian on Insanity: If you're playing on high difficulty level, and especially if you have a low level character, you will probably find this an extremely difficult level. Take heart that with practice it IS possible to run this entire level perfectly on Insanity level, even with a low level character, and with a variety of classes and squadmates. Here are some tips for survival in the coming fight:
- Consider equipping shotguns, even for squadmates who aren't trained in them. This will help knock creepers off their feet and slow their pursuit.
- Use Hammerhead Rounds in your weapons if you have them (Sledgehammer Rounds even better). Increases the chance of knocking creepers down, even if not used in a shotgun.
- Always take down the Asari Clone first whenever you see her. She's the only ranged opponent, her weapon is powerful, and her biotic knockdown can leave you helpless while creepers catch you and barf on you. A typical takedown combo is an Overload to take down her shields and a Lift or Neural Shock to knock her off her feet; then you can usually just shoot her quickly.
- Take this level VERY slowly. Rushing forward will spawn too many enemies too quickly. Whenever it's quiet stop and rest until your abilities and health regenerate.
- Consider parking your squadmates in one of the relatively open spaces and carefully scouting ahead alone. This will keep your squadmates from getting killed which deprives you of the use of their all important abilities. When Shepard triggers new enemies, quickly return to where your squad is. This will cause the enemies to "train" out into a line and you won't have to fight as may as once. The dangerous Asari Clone in particular will tend to arrive well ahead of the creepers.
- There are several vantage points from which you can gain line-of-sight on one of the Thorian "nodes" from across the center space. This gives you the chance to shoot it and take it out from safety - or at least provoke creepers to run at you one by one.
- A new Asari Clone spawns whenever you knock out a node, so be ready -- return to the safety of your squad and get your abilities ready to go.
- You will need to take out a total of six Thorian Neural Nodes and seven Asari Clones. The final Asari Clone spawns when you approach the last node. Note: You can avoid the spawning of the seventh Asari Clone by shooting the final neural node at a distance from the next room and never approaching close to the room the node is in. This makes the final section a bit easier but lowers your experience reward.
- Biotics should freely use Throw to eject enemies off the side of the chasm, especially the Asari Clones. However Lift and Singularity will also buy you time (also a lifted victim can sometimes be propelled off the edge by a shotgun or melee, and if you cleverly position yourself between a group of charging creepers and the chasm, Lift will let them simply sail over your head and into the depths). In emergencies Stasis can stop a creeper than has gotten too close, or put one of a group "on ice" while you deal with the rest.
- The best tech abilities are Neural Shock which will take either an asari or a creeper off its feet and arrest their advance, and Damping which stop the asari's ability use.
- Did you manage to save any grenades? When equipped with the Anti Thorian Gas they will take out a whole roomful of creepers and therefore should be saved for the ultimate last resort.
Destroy The Thorian Edit
Level 2 EditNote: From this point on, it is highly recommended that you use your shotgun, even if you are not trained in it. Shotguns make this entire chain of events surprisingly easier and less frustrating. This is especially noticeable on lower difficulties, where both creepers and asari clones can be killed with a single shotgun blast. In addition, using Hammerhead Rounds (or Sledgehammer Rounds if you've reached high enough level) will often knock creepers off their feet, giving your squad mates time to kill them while they are down.
This next part is very linear so just follow the path forward and you will complete the mission. However, head past and under the dead node and up the stairs, don’t worry about the creepers, they won’t wake up, well at least right now. Head up the stairs and you will run into more creepers and eventually when you reach the landing send in your squad first because there are more creepers and the close and they are determined to keep you away from the next node. If the asari is in the right position, then she can be thrown off again. Once you have dealt with the Thorian creepers and the clone, head to the opposite side of the room and access the weapons locker.
Warning: Although normally in this area you can walk to the edge of the chasm with no danger, there is a spot near the corner by the weapons locker which will kill you instantly.
In the room with the node are more Thorian creepers; now you have two options on how to deal with this problem. If you shoot the node until it bursts, it will kill all the creepers even if they aren’t up yet. However, you lose out on the exp they provide, and the node's health is directly proportional to the number of living creepers "attached" to it, so it will take longer to kill while the creepers are still alive. The other option is to shoot the node and when the creepers rise up then deal with them, then get back to shooting the node. When the node is dead move up the rubble and to the next level.
Level 3 Edit
The next room contains even more creepers and another clone. If you are sneaky enough, then you can throw the clone off and then you only have to deal with the creepers. Move into the room and take out the creepers and then look to your left as you can see the node from here. The best way to deal with it is to shoot it from this room and deal with the creepers as they come, otherwise you can get overwhelmed very quickly.
Put your squadmates in cover near the door and start shooting the node and then deal with the creepers as they come down the tunnel. Eventually you will run out of creepers and the node will run out of health and blows up. Move into the room where the node was and then put your squadmates in cover near the door as the next room has more of the same. Just shooting down the tunnel should be enough to attract their attention. So deal with the creepers and the clone as they come. When you are done head into the large room and decrypt the medical station at the other end of the room before going into the room with the node.
The room with the node also contains 10-12 creepers and they will follow the usual “waking up when you shoot the node so kill me now” routine. When all the creepers or the node is destroyed, head up the rubble and onto the next level.
Level 4 Edit
When you get up you can throw the clone or a creeper off the ledge. Unlike the rest of the rooms this one opens to the right and has a lot less enemies than the three previous ones. Take down the clone and creepers as they come, throw a few off for a few laughs, and then turn around and shoot the node. You can even do that first but remember you will lose the exp. Once the node is destroyed head down where the node currently blocked you and you arrive at the first staircase.
Head up the stairs and then you will be forced to deal with those creepers that you had to bypass earlier. They will wake up, in droves, and attack along with the clone while you are trying to climb the staircase to the last node. Take them down with shotguns, powers, gunfire, and any grenades you have left. When all the enemies are on the ground, resume climbing the stairs and onto the final level.
Level 5 Edit
Once on the top there are two rooms with creepers, and a final clone. Take down the ones in the middle and then get into cover and use the same tactics as before, or whichever tactics that work best for you. When you have dealt with the final creepers, finish off the node and you are treated to the nodes you destroyed collapsing and the Thorian falling into the abyss.
Shiala EditShiala and she served Matriarch Benezia. Talk to her and you will learn that Saren came to get the Cipher and understand the disjointed images from the Beacon on Eden Prime. She will tell you that Saren gave her to the Thorian in exchange for the Cipher and then tried to kill the Thorian to keep Shepard from getting to it. Apparently Saren knows that Shepard is searching for the Conduit and is doing everything possible to stop Shepard.
She will give you the Cipher and then her fate is in your hands. You can choose to kill her, or allow her to help the colony to recover, which will affect the colony's survival chances. Either way you head back up to the colony automatically when the dialog ends.
The ExoGeni personnel are here from their bunker, and will greet you with either respect or distrust as you learn the consequences of your actions for the colony's future. Your results here can be predicted by a simple formula, as follows:
- Colony health
- For each sidequest completed (varren meat, geth in the tunnels, etc.), add 1
- For each surviving colonist, add 1
Colony health is cumulative, so 11 surviving colonists and three sidequests nets a health of 14, for example.
- Colony leadership
Colony leadership is not cumulative; if Jeong agrees to help, it doesn't matter what you do with Shiala, you still only get 12 points.
For Feros to survive, the total value of colony health + colony leadership must be thirteen or higher. So, for example, if you kill Shiala and Jeong, you need to spare at least 13 colonists, or spare at least 9 colonists and complete all four sidequests. If you convince Jeong, to help, you only need to do one sidequest or save one single colonist. Meet this bar and the remaining colonists will thank you for your help and cheer about the colony's newly bright future. Fall short, and they'll dejectedly explain that the colony is being shut down.
With this conversation done, you can talk to the various people left, trade with Ledra, and give Gavin his data if you recovered it, or simply head straight back to where the Normandy is docked and leave this planet behind.
If you have Liara in your party she will offer to join your minds again to try and make sense of the vision, but the meaning will remain elusive. You can also choose to report to the council or not. If you do they make comments about the Thorian and how it was a problem and they should have been informed. Also they comment about if the colony was saved or not. If the colony was being shut down then the asari councilor is disappointed that the colony couldn’t be saved and the turian councilor approves saying the mission came first. If the colony was saved the salarian councilor will approve and the turian councilor will disapprove.

Mass Effect 2 Consequences Edit
Although Shiala will appear in Illium if she survives, a different colonist will appear in her place if she does not - so she does not need to be saved in order to receive the assignment and its rewards.
