pop fire up galaxy map and plan a trip to theKrogan DMZ.
Once you’re there (Aralakhsystem), fly to the planetTuchanka.
I would strongly recommend that you remain where you’ve started the fight.
Begin firing at husks, preventing them from moving too close to your team.
Attacking the monsters from the distance is the best option here, because they can’t fight back.
Once you’ve won [300 EXP] you’ll automatically trigger new cut-scenes.
Finish off by talking to the krogan scout which will trigger a very interesting cut-scene [150 EXP].
ensure to examine a krogan artifact on the wall in one of the first chambers [8500 credits].
Continue exploring the ruins and listen to a comment about a thresher maw queen appearing in the area.
Battles in the ruins
stash your game after you’ve made your way to topside ruins.
Get ready to take part in a new battle here.
After you’ve won proceed to the corridor from which the monsters came from.
Start off by eliminating the husks heading your way and as always it’s important to avoid melee combat.
As soon as you’ve noticed ravagers order the entire team to take cover.
confirm you’ve eliminated all ravagers before you leave cover.
Secure the area and then proceed towards the large statues seen in the distance.
The final battle in this part of the ruins will begin very soon.
You may now proceed towards the dunes which will trigger a new cut-scene.
Wait until you’re transported close to where the Reaper is stationed.
Luring Thresher Maw and avoiding the Reaper
Start off by dealing with a small group of cannibals.
Thankfully they won’t have any support, so you should be able to eliminate them very quickly.
Proceed towards the stairs and double-check to pick up a pistol [M-5 Phalanx] along the way.
You must now start RUNNING towards the Reaper seen directly in front of you.
Drop down to a lower level and notice that brutes have begun appearing in the area.
DON’T FIGHT these monsters and insteadfocus on reaching one of the maw hammers.
Notice that the Reaper is trying to use its legs to stop you.
Once you’ve reached the hammer interact with it [300 EXP].
Turn around and start running towards thesecond hammer.
Approach the second hammer and activate it [300 EXP].
The game will now play a very interesting cut-scene showing a duel between a thresher maw and a Reaper.

Once the Reaper has been defeated you’ll automatically travel to the Shroud facility.
Begin by listening to a conversation with Mordin.
Otherwise she’ll be alive and well.
Get ready, because you’ll soon have to decide how you want to end this quest.
After you’ve dealt with the situation in the Shroud tower you’ll witness a lot of cut-scenes.
If Eve died, then you will be attend her funeral.
Once you’ve returned to the Normandy talk to Liara and to the salarian Council member.
