==Walkthrough==
The scenario starts in Room 301. To gain points, the player can press a button between two beds to call the nurse station. Dr. Hersh will make his entry when the survivors attempt to leave. Since the elevator power is down, exploration of the hospital for the time being is restricted only to level 3F.
 
 
Moving through the [[Raccoon General Hospital/3F passage|3F passage]] to [[Raccoon General Hospital/Room 302|Room 302]], the acquisition of the [[Male Nurse's Diary]] can serve a guide to the plot. Should the player be unarmed, a Crutch can be found against the locker, while a Handgun will be inside. The Leech Man will come down one of the air ducts and will attack the player after said Handgun is picked up. It is strongly recommended, if unable to simply evade, for the player to use their new '''Crutch '''by attacking it and getting out of the room.
 
 
Again in the 3F passage, the player must go to the Nurse's Station. Inside the Nurse's Station the player can find several items such a Hospital's blue print that the character will memorize it and will obtain a '''Map '''(unless playing as George as he'll know the hospital), the '''Repair Work Memo'''. The player must move to the barricade where a short cutscene will play where Hersh will meet his final destiny by the hands of the Leech Man. After this cutscene, a nurse will zombify and Hersh will be mysteriously missing along the Leech Man; the player now can go over the barricade to obtain a [[First Aid Spray]](normal and easy modes), two very important [[Blood Pack|Blood Infusion Packs]] and can use the elevator.
 
 
Now, the elevator will be working, however it will only head to the 1F, 2F and the B1F levels; the Rooftop and B2F are inaccessible. To unlock the B2F and the Rooftop, a player must input codes in the B1F '''Elevator''' '''Control Room'''. The code for B2F is randomly selected when the scenario starts, while the Rooftop passcode will ''always'' be '''0930'''.
 
 
Unless you already know the possible B2F codes, head to 2F and go to the '''Nurse's Station'''; in addition to a '''Handgun''', '''Handgun ammo''', and '''two blood infusion packs''', the glass cabinet contains leeches and (more importantly) the '''Chemical Code Message''' (which is crucial to finding the B2F elevator code). At the end of the 2F hallway is both a room with supplies, and a stairway down to the [[Raccoon General Hospital/1F passage|1F passage]], where they'll find a door with a shutter blocking it and an [[Iron Pipe]] near the stairs.. Go to '''Night Reception'''.
 
 
If the player has [[Mark Wilkins|Mark]], they can get the '''Security Guard Manual''' file, which is needed to earn a 100% competition rate and points.
 
 
Also, the back of this room, the player can find the '''Burst Handgun''' and an Unknown Survivor. If a player talks to him, he will ask for Hemostat, however once the player has one and returns, the Survivor will be dead (('''Note: ''' The Unknown Survivor will be sometimes in the '''Waste Liquid Disposal Room''' and dead at times the player arrives; Also in Hard and Very hard modes, the players wont find the Burst Handgun, but a simply Butcher's Knife.))
 
 
The console controls the power supply for all shutters on this floor. Turn on power to the hospital shutters and enter the shutter at the base of the stairs. This leads to the hallway seen in [[Resident Evil 3: Nemesis|Resident Evil 3]].
 
 
The hallway: the '''Office''' and the '''Central''' '''Waiting Room'''. To find the other clue to the B2F elevator code ('''Piece of Memo'''), it lies in the Office's center island. The '''Central Waiting Room''' transitions to the '''Examination Room''' (take note that a Zombie Dog it encountered in the Waiting Room). The '''Examination Room''' is where the [[Card Key Level 1|Keycard Level 1]] is found, next to a dormant zombie.
 
 
If supplies are needed, the player can go to the '''Treatment Room''' (located in the bottom right of the Examination room) where they'll find '''Four Recovery Medicine Base '''(George only), a '''Hemostat '''and a Typewriter. Now exit the room and go to the upper part of the examination room passing down the windows, but a player must be cautious as a zombie will burst from the windows.
 
 
Alternately, the Examination Room can be reached through the '''Locker Room'''.
 
 
In any event, return to the elevator from either the stairs to 2F, or through the '''Office''' and to the '''Doctor's Station'''. This room contains the classic '''Blue Herb''', an [[Anti-Virus (L)|Anti Virus Large]] and '''Handgun ammo'''. You can use the elevator in this room to move to B1F.
 
 
On BF1, there are two rooms: The Reposing room, where the player will find a '''[[Typewriter]]''', a '''Scurb Brush '''and a '''First Aid Spray'''; the other room is the player's destination, the '''Elevator Control Room'''. Inside of it, a player has to input two passcodes for the elevator in order to move on to the B2F and the Hospital's Rooftop. Inside the room, the player will find: the '''Setting Manual''', and Leeches on the console to put the passcodes; it is recommended to put the '''Blood Infusion Packs''' on the floor to draw the leeches off the console, also distracting the Leech Man, if he is present. The Blood pack will slow down the enemies for a whole minute allowing the players to put one of the following passcodes.
 
 
;Passwords
 
#'''3555'''
 
#'''5315'''
 
#'''8211'''
 
#'''0930 (Rooftop passcode)'''
 
 
After putting the right codes, the player must head to the elevator and get to B2F. As soon the player is on the B2F hallway, they shall go to the room across the [[Raccoon General Hospital/B2F passage|B2F passage]]. In the room, they'll find the '''[[Researcher's Diary]]''', the '''[[Investigation Request]]''' files and a freezer that has 2 ''' Blood Infusion Packs'''. After picking any desired items, the players shall head to door near the dried up cadaver and enter the Fixed Temperature Experiment room where they will find a '''Hemostat'''. The Leech man will be your only encounter in this room. The player will have to lure it inside the main room with a Blood Pack. After doing so, the player must head outside that room and wait for the Leech Man to go for the bait. As soon the Leech Man does so, the player must set the temperature to 'High'. After a cutscene, the player will need to set the temperature to 'Low' in order for the [[Card Key Level 2|Keycard Level 2]] to be accessible to the players. If a player presses X on the Leech Man's corpse, they'll notice its true identity and if a player presses the AB-Lib, the characters will make comments on the Creature's identity.

=== Main walkthrough ===
Once the player has '''Keycard Level 2,''' it is recommended to go back the B2F and head down to the Hall's bottom, to the door where a Zombie resides (Take note that his zombie will never despawn) and use their keycard.
 
  +
The player starts the level on Room 301, and triggers the arrival of Dr. Hersh when attempting to leave. Currently, power to the elevator is out and shutters have been raised, preventing the player from leaving level 3F. To regain power to the elevators, they must go to the Doctors' station, where Dr. Hersh restores power before being attacked by leeches. This Leech Man enemy will harass the player throughout the hospital. Its attacks will put the player in BLEEDING status, and it is invulnerable to injury from weapons. Abandoning the room when it arrives is advised, though this will also waste time on the Virus Gauge if an important item could not be retrieved.
   
  +
The new objective is now to destroy Leech Man. To do so, the player must lure it to the Fixed temperature laboratory on level B2F. Power to this floor is currently unavailable, and requires a code to be entered in the [[Elevator control room]] on B1F. There are three possible combinations in the game, which can be deciphered by comparing the colours in the Chemical Code Message and Piece of Memo (Office, 1F) files, and then adding their numbers. For example, the former file refers to several colours such as carmine and cerulean, but if the latter explicitly refers to red, this is taken to mean carmine as carmine is a shade of red. In this example, the numbers next to these two colours are "1210" and "+2345". The B2F elevator code would therefore be 3555, a product of those two numbers. The access code for the Rooftop is always 0930. If the player is Kevin or Cindy, they can recover a Submachine gun from a dying police officer.
The player can go to the Rooftop to get supplies. On the roof, the player will find several Crows as well some Herbs (In Hard and Very Hard modes, zombies will be present in the rooftop, making it a dangerous room, and after a player calls the elevator, a zombie will come out the elevator attacking the player). One of the last Raccoon City Police Department officers is in the rooftop. If a player has Cindy or Kevin as a character, the Dying police officer will mistake [[Cindy Lennox|Cindy]] with his special one "Maggie" and give her the [[W:C:Guns:Heckler & Kock MP5|MP5]] and ammo for it as a parting gift. If the player has [[Kevin Ryman|Kevin]] as the character, he will say that the last chopper left and just gives him the MP5 and dies(In Hard and Very Hard mode, the cop will give both characters the Burst Handgun with no ammo).
 
   
At any point in B1F, the player must head down the corridor and use the Keycard Level 1. As entering the South Passway, a zombie will be near the boilers as well an '''Iron Pipe''' ('''Note''': the Leech Man and leeches will be absent in this room if already eliminated, however zombies will break in the room if the player stays too long). Head to the other end and reach the Waste Liquid Disposal Room where more leeches will be waiting for the player to come, near the door, the player will find a '''Green Herb'''.
+
Now with access to level B2F, the player is to immediately head to the Fixed temperature laboratory via the Laboratory adjacent to the elevator door. To kill the Leech Man, the player must lure them into the chamber, ideally with a blood pack to keep them there. If there are no AIPCs in the chamber, the player will then be allowed to operate the controls outside of the chamber and increase the temperature, killing Leech Man. The temperature must be set back to cool, however, before they can retrieve the card key.
   
  +
As the player now has the level 2 card key, they can unlock the door to the Underpass entrance and discard the item. The new objective is to obtain the padlock key so the boat can be commandeered. The padlock key is located in the Waste liquid disposal room on level B1F, but the level 1 card key is required to get access to the rest of this floor. This card is recovered in the Examination room on level 1F. Boarding the boat triggers a boss battle with the Giant Leech. The Giant Leech will generally attack with its tentacles from underwater, so it is advised the player keep to a greater distance to avoid these tentacles. If the player has not stocked up on items before triggering the boss fight, they may head back down the tunnel and finish exploring the hospital. If the Giant Leech is lured further down the tunnel, shooting a ceiling valve while it passes under it will also cause significant damage, giving an opportunity even for players light on ammunition to complete the level.
The player must head down the stairs and grab the '''Handgun ammo''' and wade through the water until reaching the other side, where the '''Padlock Key''' is located. the player must be careful as the zombie could get the player and bite them. After obtaining the '''Padlock Key''', the player must go back to B2F and go across the hallway to enter the Underpass Entrance. When the Key is used, a cutscene will play showing how the player unlocks the chain on the docked boat. In the Room, the player can find a '''First Aid''' and '''Hand Gun ammo'''. When ready, the player must check the Boat and get in it for the final boss battle.

"A hospital transformed into some kind of hive full of squirming things. We pushed on and pushed the repulsive image from our minds."
— Localized level description

The Hive, known in Japan as "Den" (巣窟 Sōkutsu?), is the third scenario featured in Resident Evil Outbreak. It takes place predominantly in Raccoon General Hospital and the sewers below.

Plot

Three survivors take shelter at the besieged, though largely-abandoned Raccoon General Hospital. Dr. Hersh walks in them in Room 301 by accident, and suggests they leave the building immediately. With power to the elevators having suddenly gone out, Hersh leaves to turn it back on. He is attacked by leeches drawn to a zombie-bite on his arm, and is used as a vehicle in which they can assume a humanoid form, also known as the Leech Man.

After that, the team took the elevator to 1F. Once there, they went to the Office and grabbed the "Part of Memo" file, which contains the Carmine Code. Then they went back to the elevator and took it to B1F. When they get to B1F Passway, the Leeches are on the control panel. By the time the team killed the Leeches, the Leech Man appears. They used the Blood Infusion Pack on the floor to distract him. Then they quickly return to the panel and input the code. They exited the room immediately and took the elevator to B2F. Then they went to the B2F Passway, took the last Blood Infusion Pack and went to the Fixed Temperature Experiment Room. The Leech Man appears and they spill the Blood Infusion Pack into the floor to distract the monster. Then they got to the safe chamber and set the controls to "High". The Leech Man dies from the intense heat.

Once the Leech Man was dead, the team sets the temperature to "Low" and finds the Card Key Level 2. They used the Card Key to unlock the south door to the Underpass Entrance. They need a key for the padlock. After obtaining the Card Key Level 1 from the Examination Room in 1F, unlocking the south door in the BF1 Passway using the Card Key, and found the Chain Key in the Waste Liquid Disposal Room, they removed the chain from the boat in the Underpass Entrance. The three got in the boat and he started it. Something was blocking, so they got out and the boat crashes. There was a massive Leech hive, along with the "Queen Leech". After defeating the Queen Leech, they escape the sewers.


Walkthrough

Main walkthrough

The player starts the level on Room 301, and triggers the arrival of Dr. Hersh when attempting to leave. Currently, power to the elevator is out and shutters have been raised, preventing the player from leaving level 3F. To regain power to the elevators, they must go to the Doctors' station, where Dr. Hersh restores power before being attacked by leeches. This Leech Man enemy will harass the player throughout the hospital. Its attacks will put the player in BLEEDING status, and it is invulnerable to injury from weapons. Abandoning the room when it arrives is advised, though this will also waste time on the Virus Gauge if an important item could not be retrieved.

The new objective is now to destroy Leech Man. To do so, the player must lure it to the Fixed temperature laboratory on level B2F. Power to this floor is currently unavailable, and requires a code to be entered in the Elevator control room on B1F. There are three possible combinations in the game, which can be deciphered by comparing the colours in the Chemical Code Message and Piece of Memo (Office, 1F) files, and then adding their numbers. For example, the former file refers to several colours such as carmine and cerulean, but if the latter explicitly refers to red, this is taken to mean carmine as carmine is a shade of red. In this example, the numbers next to these two colours are "1210" and "+2345". The B2F elevator code would therefore be 3555, a product of those two numbers. The access code for the Rooftop is always 0930. If the player is Kevin or Cindy, they can recover a Submachine gun from a dying police officer.

Now with access to level B2F, the player is to immediately head to the Fixed temperature laboratory via the Laboratory adjacent to the elevator door. To kill the Leech Man, the player must lure them into the chamber, ideally with a blood pack to keep them there. If there are no AIPCs in the chamber, the player will then be allowed to operate the controls outside of the chamber and increase the temperature, killing Leech Man. The temperature must be set back to cool, however, before they can retrieve the card key.

As the player now has the level 2 card key, they can unlock the door to the Underpass entrance and discard the item. The new objective is to obtain the padlock key so the boat can be commandeered. The padlock key is located in the Waste liquid disposal room on level B1F, but the level 1 card key is required to get access to the rest of this floor. This card is recovered in the Examination room on level 1F. Boarding the boat triggers a boss battle with the Giant Leech. The Giant Leech will generally attack with its tentacles from underwater, so it is advised the player keep to a greater distance to avoid these tentacles. If the player has not stocked up on items before triggering the boss fight, they may head back down the tunnel and finish exploring the hospital. If the Giant Leech is lured further down the tunnel, shooting a ceiling valve while it passes under it will also cause significant damage, giving an opportunity even for players light on ammunition to complete the level.

Further notes

  • The Leech Man will haunt the players through every room via the ventilation system, regardless the difficulty, it wont be able to reach the rooftop. In easy and normal modes this would be the only "safe area" from the hospital. However, in Hard and Very Hard difficulties, zombies will come from the elevator and the Crows will respawn every minute.
  • In Hard and Very Hard modes, if a player kills a leech, another will respawn and drop from the ceiling.
  • Only Cindy and Kevin will receive the Sub Machine gun from the Dying police officer; This weapon is recommended for the Giant Leech boss, as it will cause zero damage to the Leech Man (0HP), however in Hard and Very Hard modes, they will only receive a Burst Handgun instead.
  • Randomly, players will find an unidentified civilian within the hospital's installations. If players find him before getting the BF2 card, he will be alive and request an Hemostat to stop his bleeding. Regardless of whether the player tries to get him the medicine or not, he will be found dead if the player tries to talk to him again.
  • Of all the elevator's passcodes, the only one that won't ever change is the Rooftop pass code.
  • The diaries found in this scenario serve as items, taking space in the character's item slots, however they have no use and will be stored in the Files.
  • Melee weapons are recommended to be used in this scenario, leaving the fire weapons for the boss battle.
  • If a player or AI dies at any point in the mission, after the Leech Man is killed, that AI or Player's corpse will be used to create the new Leech Man, and this one will be unkillable. It is highly recommended that you watch your teammates healths on higher difficulty, for if they die it could present problems in the future. In Hard and Very Hard difficulties, the possessed AI and the Leechman will both haunt the player at the same time.
