Get the vials from mutated assistants | Chapter 4 - Dr Kessler DI Riptide Guide
Last update: 11 May 2016
Open the nearest door and head for the glasshouse, getting through a quarantine zone. When you get there, ignore Kessler assistants on the upper balconies - you can't hurt them for now on. Instead, begin exploration of the lower level: beware of mutated scientists.
Your actual target is a red ladder shown on the screen above, which is behind the stairs you've used to get to the greenhouse. Grab it and climb.
Eliminate the closest zombies and head right. Soon, you'll run into a first Grenadier, which is one of Kessler assistants. They are distant fighters, throw part of their bodies at you. So try to shorten a distance ASAP and use a melee weapon to kill him.
When you get him, search his body and pick up a vial. Attention: if body of any of assistants fall down, localize it at the end, because you'll go back there after all.
Heal up (there are energy drinks and med-kit nearby) and resume wandering. Defeat more mutated scientists and use a panel (screen above) what pulls out a bridge. Run through it and get to the second Grenadier. After killing him, pick up another vial.
Now go left. In this area you find two last Assistants, so be careful. Run forward and kill the third one.
Return to the previous balcony and go left. The last one Assistant is stronger. If you can't eliminate him in melee fight, move back and use grenades or molotovs. Pick up vials.
