Dead Island: Riptide Walkthrough Part 22 – Science News Daily: Way Of Science
The survivor's camp has officially moved to Halai now. This will open up Dr. Jane Hanson's Team Quests so you should look into it when you can. You will also get the side quest, "Stop The Madness" to find Marcus Villa and stop him from hurting anyone else. Still, the first thing to do is go talk with Harlow to learn more about Dr Kessler and about getting to him.
Head to the North from the Survivor's Camp and grab a car. It is just a lot easier to get there on 4 wheels opposed to your 2 legs. Drive along the road to the Destroyed Road. Go over to the West of there and you will find the entrance to the BioSphere where Dr. Kessler is. Deal with the few zombies around the entrance and get inside after that. Head on up the slope in front of you on the other side of the door.
Dr. Kessler is surprised that someone has made it in but he is not about to objective to getting some help once he learns what you are after. He will ask you to go into the green house and collect 4 reagents from his lab assistants. Time to start the next part of this.
Head through the double-doors behind Dr. Kessler. Be sure to search the room thoroughly as there is another Secret File to be found in this room. When you are ready go on through the next set of double doors and into the green house itself through the sanitation room.
Once you make it into the green house itself it is time to get ready for more fighting. You will also be introduced to a new type of zombie: Grenadiers. They are in bright yellow Hazmat suits. This means that they are immune to fire damage so do not even try to roast them a distance. They also have a nasty habit of tearing off chucks of themselves and throwing it at the Immune with Toxic results. You can find the 4 Grenadiers that you need to kill by looking at your map and locating the red skulls. You will also encounter Mutated Scientists. They are much akin to Walkers: slow and easily knocked down. All they will do, given the chance is grab and bite you.
The first reagent is not too hard to get a hold of. Head on down to the right of the door you came through. Climb on up the red ladder and you will find Mutated Scientists but also one of the Grenadiers that you are after. Take out the Scientists quickly so you can focus on the Grenadier. He is a lot harder to kill than the others so move in quickly and attack with some of your best weapons. Loot his body after the first and you will the first of the four samples that you need.
Head over to the right and up the stairs that the Grenadier came down. Go on over to the left after that and down the stairs toward the next pair of Mutated Scientists that you see. Kill them, loot the area and look on the wall behind where they started. You will find a switch. Use it to open the nearby door so that you can get through. On the other side of that door you will find another Grenadier and more Mutated Scientists. Kill of the scientists then go after the Grenadier to claim the reagent from his re-dead hands.
