(7) Going down into the sewers Deus Ex: HR Guide
Last update: 11 May 2016
You will be informed of the next step in a while, but you can choose to go to the sewers at once. The most obvious solution is moving the crates #1 to find a switch #2. Interacting with it will lead to opening the secret passage on the right.
Reward: 750 EXP.
Head down the stairs #1. You need to be cautious, as there are two enemies waiting below #2. If you don't mind killing them both, you can shoot now and use the element of surprise.
If you prefer to only knock them out, go down to the very bottom and wait for one of the guards to get near the stairs #1. Try to surprise him. The second guards should be sitting on the bench #2 - you need to carefully approach him. It would be good use the chance and look into the local lockers.
If you want to avoid the enemies, stop by the two green barrels while going down the stairs #1. Note that here you will be able to jump to the yellow metal supports, using them to pass above the enemies #2 who of course won't consider looking up.
An alternative route implies finding a fragile wall fragment inside Sandoval's apartment #1. In order to destroy it, you would of course need the Punch Through Walls augmentation. Carefully jump down the pipes below you #2.
After reaching the very bottom, crouch and go through the small hole #1. You need to be careful, as there are two enemies in the area. Use the moment and take a look inside the lockers.
Reward: 950 EXP.
Regardless of the previously made choices, you need to reach the big red container (screen above). Get inside and you will find a ladder leading into the sewers.
