Travel to Mesana in the Nimbus Cluster and land on Lessus. Take a Biotic heavy team for this one. Once you land, check the shuttle car to the right and then in the left corner will be an Assault Rifle Stability Dampner. Go inside and make your way down the ladders until you come to a living area. Go straight left and there will be an open double door with a Pistol Melee Stunner on the floor. Behind that will be a Gallae's Electronic Signature for an Upgrade Kit. Make your way along the back side of the long room and collect the datapad on the conference table. Just next to the table will be a tall terminal. Use that. Make your way to the far end of this room and approach the broken door. Just to the right will be a small room with a safe (credits), a Sniper Rifle Spare Ammo mod and a datapad. Collect them and then go towards the broken door.
At the broken door, turn left and mantle over the barrier. Open the door on the right. In the large window room, go through the door on the right to meet an Asari Justicar (Samara if she's still alive). Check the PDA for Asari Widow Message by the dead Asari to the right in the next room for a new Citadel Mission. Go through the door to the left. Outside, go down the stairs to the courtyard.
Meet the Banshee. Try to take the Banshee down as quickly as possible. They are hard to hit because of the way they move but once they get close, they slow down. If you time your attack just right, you can stop the jumps by hitting them just as they jump. Kill her quickly and then clean up the Cannibals as they approach. Make your way to the far side of the courtyard and into the building. Inside the building, check the left side for a broken door and check right for a computer. Go through the door on the right and kill the Cannibals in the distance. A Marauder will appear to assist them but they should pose no threat at this point in the game. Kill them and then investigate the small room on the left for a Disciple and the Serrice Council Shoulder Guard. Go around the top floor to another room just before a dead end to find two computers and a safe and a workbench.
Head down the big stairs in this room and a fight will start. You'll be attacked by a Banshee and some Cannibals. Try to draw the Banshee to the stairs and up so you don't have to fight both her and the Cannibals at the same time. Once she's dead, clear out the Cannibals as they drop in from the far side. Make your way up but watch out for some modified Cannibals. They will heal a little at a time so it's best to focus your squad on them to kill them quickly. Go through the door at the other end.
In this next room, move along the wall to the left and you'll come across an Assault Rifle Precision Scope. Check the middle of the room for a dead Asari Commando. Go through the door at the far end of the room and activate the terminal inside the elevator. When you reach the bottom floor, run straight through the middle of the room and grab the Med Kit. Activate the Bomb Console.
This fight is pretty tough. You'll be attacked by two Banshees and some Husks. I recommend going for the Husks first so that you have plenty of room to move around. Once they are done, focus on one Banshee at a time. Pull the shields down and the constant fire should keep them from teleporting. Feel free to use Medi-Gel to revive teammates here because this is the last fight here. Make sure you keep backpedalling around the area and keep firing. When they are both dead, activate the Bomb Controls. When you get outside, be prepared for a Paragon Interrupt. If you play Paragon, you definitely don't want to miss this one.
