Mass Effect 3 Hints
Executor's Office.
1 of 12: Go through the door in the back of the area, then open the next door to get the drop on a couple of Cerberus troopers on the other side of the room. After firing at them, hide to the left of the doorway for cover as you finish them off, plus the troopers that come down the stairs on the left side of the room.
2 of 12: Go up to the top of the left set of stairs, then wait there as troopers appear on the upper walkway of the next room. They're really easy to shoot as they drop down and briefly hover over the floor. (Note that if there's a turret up there, you'll have to take cover rather than shooting down troopers as they descend.)
3 of 12: Check the right side of the room for a med kit and an Assault Rifle Piercing Mod, then go through the door in the back of the room. Open the next door, then quickly shoot down the Cerberus guardian over on the right while his back is turned. Take cover to the left of the doorway and send your squad into the room.
4 of 12: After the room is clear, search it for ammo, a medical station, and a Recon Hood. Past the door on the left side of the room is an M-76 Revenant assault rifle and a locker you can loot for credits.
5 of 12: In the short hallway past the room, you'll need to figure out how to open the locked door.
6 of 12: Take the Sniper Rifle Extended Barrel mod from the nearby shelves and use the weapon bench if you want to, then cover-climb through a window. Go through the open door and use the control in the back to get the elevator going.
7 of 12: In the next area, check the central hallway for an M-25 Hornet submachine gun, then search the unlocked room on the left for a Pistol High Caliber Barrel mod and a Securitel Helmet. (The adjacent locked room can't be entered yet.)
8 of 12: On the other side of the hallway is a room with a Pistol Piercing Mod, and another room with two interactive terminals. One terminal will give you credits, and the other will unlock the above-mentioned locked door. In the room past it is an M-358 Talon pistol.
9 of 12: Go through the room with the two terminals to reach a spot where you can ambush two unaware Cerberus guys. Go through the door in their room, then cover-climb through the window on the right and look for some credits to salvage on a counter.
10 of 12: Move down to the other end of the room, looting the medical station on the way, then take cover next to the rightmost broken-out window. Cerberus troops will drop into the area ahead, and that's a good position to take them down from. (Note that you'll need to watch for ones going along the hallway to where they can shoot you through the side windows.)
11 of 12: Go to the end of the hallway to find a doorway labeled "Executor," then look in the area to the right of it for a medical station and a Sniper Rifle Piercing Mod.
12 of 12: Go up the stairs past the doorway and open the door to get a lengthy cut-scene and the next objective.
