After speaking with the Illusive Man and obtaining the location of the derelict reaper, enter your galaxy map and travel to the following location:

Hawking-Eta > Thorne > Derelict Reaper.

Dock with this to start the mission.

Once aboard, move up and through the first door, around the first corner you will find a small lab containing two wall safes, a terminal and a work log you can check out. Further down the hallway you will find another log and a medstation if you need it. Continue down the passage to the right to watch a short scene.

After the cut scene, you will find yourself on a catwalk of sorts, head forward and to the left for another work log and then follow the path over to the right. As you reach the explosive crates, a group of husks will attack you. Defeat them and continue down the nearby ramp. At the bottom you will encounter several more groups of husks. As the numbers are a little overhelming, feel free to retreat back up the ramp if you start to get crowded. When they are all dead, check out the work log and continue onwards.

Work your way through the first few groups of husks and keep an eye out for the Sniper Rifle upgrade (right).

At the top of the ramp you will see a pair of Husks get taken out and be warned of a sniper in the area. Check the immediate area for a box of Power Cells , a canister of Refined Platinum , a new Research Project (Sniper Rifle Damage) and a Terminal that can be used to earn a few easy credits.

Continue into the open area on the left until you head down a small ramp. At the bottom here, fight off the Abominations and Husks that climb up from the left and the right and the large group that charges at you from the far end of the room. Be sure to keep your eye on the Scion that appears back there as well as they can do a lot of damage in a hurry if you get caught in the open and are exposed to its ranged attacks. Once again, retreat a short way if you start to get surrounded or you are likely to be heading back to the previous autosave!

Try to kill the lesser enemies before the Scion gets into attack range (left). Later, when you see the pair of Scions coming, retreat up the ramp to kill the lesser enemies out of Scion attack range (right).

Once the room is clear, go to the back of the room to find a work station, Med Kit and a hackable research terminal for a new Research Project (Heavy Skin Weave) and when you are ready to progress, look to the left of the ramp you entered from to find a tunnel containing a bypassable door. Open the next door here for a scene.

After the scene, defend yourself against the horde of Husks and Abominations that decide to visit you by climbing onto the catwalk. Once the first group is dead, descend the stairs in front and look just to the right and you will see another group climbing up onto the walkway. Retreat up the stairs as you are going to have to kill about twenty of them whilst a Scion also appears from further ahead. Once they are all dead (including the Scion), cruise down the stairs, around the crates and up the stairs on the other side.

Head down the ramp here to meet lots of Husks, Abominations and a Scion. Have fun, you’ll be doing this twice!

At the very top here you will find a Terminal and if you head on down the catwalk to the left you will find a Med Kit if you require one. Return to the top of the ramp and move a short way past it to trigger another wave of Husks. Kill them all before you continue. In this area, examine the Terminal before going down the ramp to the right. Find the next pair of stairs leading down and as before, as you reach the bottom, Husks and Abominations will start crawling over the sides, so return up the ramp and deal with them and then take down the Scion when it arrives. Go back down the ramp and mop up any remaining Husks before climbing the stairs on the opposite side.

At the top of the ramp, look to the right for a Terminal , before heading forward down the next ramp. As you reach the bottom, two Scions will appear on ramps in front of you and a group of Abominations and Husks will start to climb over the railings as well, just to mix things up a bit! Immediately retreat up the ramp and down the other side a little to break line of sight with the Scions so that you can kill the Husks/Abominations without having to worry about ranged attacks as they come to get you. Once the minor enemies are done, take down the Scions from cover – try to save the explosive containers at the bottom of the ramp and shoot them when they get close. When the Scions are dead, move to the bottom of the ramp and kill any remaining baddies in the area.

Continue around the walkway to the next ramp leading downwards and descend. Eliminate the Husks that climb up to meet you and as you do that, you would do well to notice a pair of Scions slowly making their way up a nearby path to meet you. Retreat and take out the Husks before focusing fire on the Scions. Mop up any stragglers you may have missed and pick up the Power Cells in the corner before making your way along the walkway the Scions came from and bypass the security lock on the door. Grab the Reaper IFF from the console here and snaffle the contents from the nearby Wall Safe before heading through the next door.

Kill the final group of enemies (left) and then pick up the Reaper IFF (right) in the hallway behind them.

After the scene, have a quick look at the room; there are three long walkways running parallel to each other and linked together at the front and back by bridges. At the far end from the entry is the Reaper Core. As you approach it, the Core will close and send out a pulse of energy that summons bad guys. Within seconds, Husks and Abominations will begin to climb up onto the left and right platforms and you will need to defend yourself from the onslaught.

To make this a little easier, we recommend chilling in the back corner of the left platform (there is also a laptop here to pick up). Note that the Reaper Core will open whilst you are fighting the smaller enemies so try and get a few sneaky shots in at it whilst you have a break in the fighting. Once enough damage has been done to it, the Core will seal itself once again and summon another wave of hostiles.

Continue to defend yourself, dispatch minions and shoot the Core when it reveals itself until it is destroyed and a scene ensues. Mission complete!

During the following conversation, you need to be sure to hang onto the Geth (named Legion as you will find out later) that has helped you during the mission. Once you are back aboard the Normandy, you will be able to decide its fate, plus if you want, it can also join your squad later on. We highly recommend keeping it as a squad member to gain full benefit from the story especially if you plan on playing Mass Effect 3 and wish to see everything there.
