Walkthrough
Biohazard continues the storyline after the Plague City quest. The plot deepens as the player uncovers the truth behind the plague.

To start the quest, the player must talk to Elena in the house Northwest of East Ardougne, Northeast of the pub.

She will tell the player that she was able to collect some good samples of the plague, but unfortunately the Mourners took all of her equipment.

She now needs someone to sneak back in to try to find it. She suggests that the player should go talk to Jerico, since the tunnel used to get in before has been sealed off.

Getting into West Ardougne
Jerico lives in a house just south of the northern bank in Ardougne and just north of the church. He will tell you that he has arranged for Omart to help create a rope ladder to get over the wall.

Omart is found west of Ceril Carnillean's house in East Ardougne, just south of the castle. He is located outside of the south-east corner of West Ardougne's walls. He will tell you to talk to Jerico.

Return to Jerico and talk to him, then search the cupboard nearby to find some bird feed and grab a pigeon cage from the back yard.

Now head to the watchtower, directly North of Omart. Stand in the corner where the two spiked fences meet and use the bird feed on the watchtower fence.

Open the pigeon cage to release the pigeons. They'll immediately fly into the tower to eat the feed. This will distract the guards.

While the guards are distracted, go back south and talk to Omart. He'll help the player get over the wall.

Finding the Mourner Headquarters
Head to Martha Rehnison's house (first used in Plague City). It is located to the north of the dungeon in the middle of West Ardougne.

Pick up the Rotten apple on the east side of the house, and squeeze through a gap in the fence on the west side of the Mourner's Headquarters. You will now be standing in the back yard of the headquarters.

Right-click to use the rotten apple on the cauldron. Accidentally eating the rotten apple does not cause damage. However, you will need to go back and get more if this occurs.

The apple will dissolve into the cauldron. Squeeze back through the fence and walk around to the front of the building, and attempt to go inside by clicking on the door. One of the mourners will tell you that the player is not permitted inside because several mourners are ill with food poisoning, and are waiting for a doctor.

Using a medical disguise
Head to Nurse Sarah's house (which is in the large building south-west of the West-Ardougne church), and search the box in the house to obtain a doctor's gown. Players may obtain two by using the drop trick.

Equip the gown and go back to the headquarters. The medical professional attire will allow the player to enter freely. The gown must be equipped each time the player needs to enter the headquarters.

Infiltrating the headquarters
Go upstairs and kill a Mourner (level 13) while still wearing the doctor's gown. A key will automatically be placed in the player's inventory. Use the key on the gate to get inside the caged room. Search the crates to find Elena's distillator.

Exit the Mourner Headquarters and head back to Omart at the south-east corner of West Ardougne. Kilron will help the player get back over into East Ardougne. Alternatively, players can head through the sewers because they are no longer blocked. Go to Elena and give her the distillator.

Obtaining the samples
Elena will extract a sample of the plague, but the results of her test are strange. In order to get further results, she needs more help. Elena will give the player a plague sample, liquid honey, sulphuric broline, and ethenea. (WARNING: The plague sample will disintegrate if you teleport)

The plague sample is extremely fragile! Any of the following will cause the sample to break.
 * Any combat
 * Teleport spells
 * Teleport tablets
 * Teleport house portals
 * Spirit trees
 * Teleportation jewellery (Amulet of glory, Ring of dueling)
 * Skull sceptre teleport
 * Cabbage port
 * Clan Vexillum Teleport

Any of the following will not cause the sample to break.
 * Charter ships
 * Fairy Ring teleporting
 * Failing agility shortcuts
 * Balloon transport system
 * Canoes

Note: If any of the samples break, players can get them replaced by talking to Elena. It might be wise to use the Drop trick to get a second set from Elena. The extra set can be banked. This prevents the need for a trip back to Ardougne in case of an accident.

An easy method to accomplish this step is to bank only the "Plague Sample" in Ardougne bank. Then walk/run to East ardougne docks and take the boat to Karamja (30 coins); on the same dock you arrive at there is a charter service. Take the charter service boat (at a charge of 1,600 coins) to Port Sarim, where you can then walk due West to the Chemist. You are then free to teleport to Varrock. Pick up the plague sample and walk to the gated area for the next step.

Another easy method is to bank everything in Ardougne, tele to Falador, pick up the three vials, then continue to Rimmington to speak with the Chemist.

Traveling to the chemist
Take the samples to the chemist in the western-most building in Rimmington. Talk to him with the four items in your inventory. Say that Elena needs some touch paper for Guidor. DO NOT mention the plague sample or else he will take it away. The chemist will give the player touch paper.

Ask the chemist if he has any ideas on how to get the samples past the guards in Varrock. He will suggest giving a vial to each of his three helpers: Chancy, Da Vinci, and Hops. They are located right outside the chemist's house crowding around a fire.

Give Chancy the liquid honey, Da Vinci the ethenea, sulphuric broline to Hops.

''Be extremely careful in the next few sections! Read the steps ahead of time. They require lengthy walks, and errors can drastically increase the time it takes to complete the quest.''

BE SURE TO GET THE ROBE BEFORE YOU GO TO THE DANCING DONKEY OR YOU WILL HAVE TO GO BACK TO ELENA AND START THE QUEST OVER FROM THERE.

Preparations
The samples and paper need to be taken to Elena's mentor, Guidor, in Varrock.

But before you head there, buy both parts of the Priest gown from Thessalia's Fine Clothes located on the west side of Varrock square for 10 coins. These are NOT the same as Monk's robes!

Next, go to the south-east part of Varrock where one guard stands in front of a gate. Try to use the gate. The guard will search the player, but he won't find the plague sample. Use the gate again, and the player will be allowed to pass.

Head to the Dancing Donkey Inn (marked with a on the minimap) and talk to the chemist's assistants to get the vials back. '''Your inventory MUST have space for the three vials. Having a full inventory will require you to obtain a new set from Elena.'''

Note: The guard does not check players leaving the area, but does when they attempt to enter. There are ways to leave the area and get back inside without the guard confiscating the samples. Players can use the Telekinetic Grab spell by dropping the vials before entering the gated area and then casting the spell from inside the gate. If the spell is too high of a level, drop the vials inside the gate before leaving. Players have two minutes to run to the bank and return before the items disappear.

Guidor's house
Equip the priest gown and head to Guidor's house in the south-east corner of the gated area. If attempting to enter, Guidor's wife will tell only let the player through while wearing the robes.

Talk to Guidor and give him the vials and sample. After analysing the sample, he will come to a surprising conclusion. He tells the player that they have been lied to, and questions why.

Returning to Ardougne
Return to Ardougne and talk to Elena. She will tell the player to talk with King Lathas. The king is located upstairs in Ardougne castle, just south of Elena's house.

When told that the plague is in fact a hoax, the king replies that he did it for the best of his people, and that it protects them from a "far greater danger". He then tells the player about King Tyras's (the king of West Ardougne and Lathas's brother) journey towards the west. That he has been corrupted by drinking from the Chalice of Eternity and so the wall has been erected to protect East Ardougne.

Trivia

 * Da Vinci is a reference to the famous multi-talented Italian, Leonardo Da Vinci.
 * One thing that lends credence to the fact that the plague is fake is that an adventurer can talk to or fight any citizen of West Ardougne (without a gas mask), while not receiving any damage whatsoever from disease.
 * The tunnel to West Ardougne can be used to leave the city, but the game states it is closed when trying to go back in.
 * Guidor's wife, even when playing as a female, will still refer to the player as "Father".
 * Even though the vials received from Elena disappear upon teleporting, after talking to the Chemist the player is able to teleport with the vials without them disappearing.

 * When talking with the chemist's assistants, players can say that it is always sunny in RuneScape. This is a reference to RuneScape having no other weather.
 * Before Underground Pass was released, the player was given a Lathas' amulet which had a green centre gem. When the quest was released, the gem turned red.
 * If you tell Elena that it is hard to say good bye after she gives you the samples,she will reply by saying that she has feelings for the player too.
