Chapter 5 - part 3 K&L: DM Guide
Last update: 11 May 2016
Proceed to the stairs once you've killed all nearby guards (screen). Lynch may join you here, because you've already secured a safe passage for him. Furthermore, you will be going to the upper level, so you won't get attacked from many different angles. You will receive an updated task here. Read it.
New objective: Find An Exit To The Roof
The area in front of you should be guarded by at least two enemy guards. You will have to take them out quickly. It shouldn't be too difficult, mostly because there aren't too many civilians out here. Make sure that Lynch is staying somewhere behind. Enter this new floor carefully and try to secure it. You will have to be thorough here, so you won't get surprised by anyone later during the course of this mission. Remember that Lynch is vulnerable to enemy attacks, so you can't let anyone get closer to him.
Now you will have to turn right. You should be able to find a new staircase (screen). Go there now in order to get closer to the highest level of the nightclub. You can also order Lynch to get here, however you must be sure that he'll be safe. Proceed to the highest floor (without Lynch).
There are only a few civilians out here, so you shouldn't have any problems locating the guards. One of your enemies should be standing in front of you, near the balustrade (screen). You can surprise him if you're very lucky. Once he's gone, proceed to your right. You will have to go around the lower room using the nearby balconies. Thankfully, it's not so dark out here, so you won't have to be moving very slowly.
Keep heading towards your current destination. You will encounter several guards along the way, however you shouldn't have any problems killing them. Lynch should be moving fairly close to you. Move him back once you've reached a new corridor (screen). It's very important, because you'll probably encounter three new guards here. Use the pillars and walls for much needed cover.
As you've probably noticed, there are some signs on the nearby walls. Use them to get to the exit. Remember that you don't have to be in a lot of hurry. Go to your right and then proceed straight ahead. You will have to approach a small door which can be found to your right. Lynch may follow you right away, because you won't encounter any new guards, so his life won't be in danger.
