Gain access into the keep | Chapter 4: A Friend in Need Thief Guide

Exit the demolished square

For the time being, you can take your time so, I recommend that you take a careful look at the demolished square. At the guard corpses, you will find a total of four Coin Purses - 11+13+16+18G. Take the only available passage, by turning left. While following the corridors, collect the Poppy. After you reach the end part of the ledge, jump to a platform below [The Keep - Pipeline] and proceed to the East.

Start running as soon as the flames disappear

Go Eastwards. If you do not want one of the planks to collapse under your character's weight, crouch and start moving ahead slowly. This will allow you to reach the fragment of the balcony with a Gear - 3G. Fortunately, even if the plank collapses, this will pose no threat to Garrett's life (you will only miss the opportunity to collect the gear. In such a situation, walk over the pipe to reach a ladder, thanks to which you will return to the upper level. In both cases, you will reach a section with flames. You need to watch out, because your character mawy catch on fire and, as a result, he will lose a lot of health points. You can use Swoop to avoid the flames, or simply run. At the very end, enter the sprinting mode, because you need to reach the tunnel entrance before the pipe, on which you walked, falls down. Follow the very short tunnel and wait for a good moment to run towards the exit [The Keep - Engine Level] that you can see in the distance. You need to time it well, or otherwise Garret will be squashed.
