This is the best route to take to get to the end of the Shadow Corridor, as it allows Shepard to get away from the Agents and Virmen for a little while. You will have to cope with a lot of Agents and Engineers, though; it is impossible to avoid them.
Grab the terminal on the left for the loot here. Then, at the end of the room, you can get out onto the ledge and climb to the top. Use the lasering laser to tag the Assassin on the far right, then hack around to take him on head-to-head.
Until some time later, you will see in the main menu that the Overlord has not been entirely destroyed; much of it has simply fallen apart. You may be able to open up a small section to reveal a new area. Shepard can clean up a lot of the data from the Shadow Broker's fall by entering the Data Core, where the majority of Sarifall's data is stored.
Combat Strategy: The first room will contain Engineers and Shadow Broker Agent with some Combat Drones. Kill the Engineers first, using the Siphon to get the Hardpoints quickly. After that, put your focus on the Shadow Broker Agents. You are finally going to get some action.
Combat Strategy: Whoever is guarding the hallway is missing, because there's a squad of Shadow Broker Mercs, some Black Widow, Blades and Vanguard at your feet. Make sure to kill the Vanguard first, because they can't be revived, since there is already a Shadow Broker Agent alive for a revive.
Combat Strategy: There are now about a dozen Engineers and Shadow Broker Agents in here, including a Black Widow and Vanguard. Take care of the Engineers first, by killing them all in this room. After that, deal with the Vanguard quickly with the Assault Rifle. The Black Widow can be locked down with the Kinetic Field, so she's not much of a threat. 7211a4ac4a
