1
You wake up to an alarm. You feel asleep when you were supposed to be watching the monitors. You're not doing your job very well as a security guard, but nothing has ever occurred at the lab before.
2
You go outside to properly see what is going on, but because of the blackout that just occurred, lights are now ineffective so you are forced to use your flashlight. You walk around to inspect the area, with the occasional screams of terror sounding the halls. You eventually start to come across dead bodies. As you see that whatever is going on, it is clearly lethal. You pick up your gun so you will be able to defend yourself from whatever did all this. You hear a sound coming from behind you.
3
The scientist, whose name is Larry, leads you toward Subject Zero's cell.
"And remember that the only way to kill them is to shoot them through their heads. That's where the Reanimators are and killing the hosts doesn't ease their control over them," the scientist advises you.
"How do the Reanimators still get blood from their hosts despite the fact that the hosts are dead?"
"When the Reanimators take command over the body, they can keep all the body parts intact and can have the heart continue to function after the host is dead."
"What about Subject Zero? A bullet to the brain for him as well?"
"I don't know."
"What do you mean, you don't know?"
"Look, Subject Zero has suffered a massive mutation. We don't even know if the brain is in the head anymore. His original Reanimator has completely altered his anatomy. The only way to make sure that Subject Zero dies is to either annihilate every cell in his body or use the bionic weapon. Only one of those ensures a confrontation with the monster."
"You're right. Going for the weapon is our best bet."
You reach Subject Zero's cell with minimum trouble, having only to deal with a few infected people.
4
You realize these people must be dangerous, but you still don't want to kill them and so you run away. You realize you have to get out of here, but without knowing more about the situation, you could find yourself in a very bad situation.
5
You enter the room on your right, but as soon as you open the door, you are snatched by a horde of people, dragged into the fray, and eaten alive.
6
As you try to walk past the dead corpses, they start to come to life and bite you. Even though you can shoot them, there are far too many for you to kill, and so they devour you.
7
Deciding not to take any chances with the closet, you leave the room.
8
You try to insert the antibiotics into Subject Zero's mouth. However, getting that close to his mouth is one of the last things you should do. He kills and feeds on you.
9
You try to find something in the shelves, but Subject Zero extends his hand and snatches your head clean off.
10
You hit the Abomination with the broom, but it breaks and the Abomination quickly kills you.
11
You turn on the lighter, but the Abomination hears the sound you made and unfortunately, the fire doesn't start immediately. The Abomination lunges at you and kills you.
13
Selfish Ending
You charge through the group of zombies in front of you and because you have thinned their ranks, you manage to get through the group and run toward the door. You get outside and into the city. You are free and have survived the horrors inside. Dealing with the situation so it doesn't get out of the lab is someone else's problem.
14
You leave the room and immediately try to escape Subject Zero. However, after he has finished with Larry, Subject Zero hunts you down, following your scent, and kills you.
15
You look around. The storage is filled with various different things, but what is most important is the element of surprise. You see a broom, a bucket, some weird liquid, a rope, a metal plate, a pair of scissors, and a lighter.
16
You throw the glass at Subject Zero's face. The glass breaks and shards fall to the ground. Subject Zero looks at you.
17
You stab the Abomination with scissors. The wound quickly heals and the Abomination kills you.
18
You take a look at the sight behind the shelf and see an almost completely devoured human carcass on the floor. The vent cover is open and you guess that the creature went there after it was done feeding.
19
You start to shoot the zombies in your way. You notice that only the bullets that hit their heads cause them to permanently fall down, so you focus the rest of your bullets at their heads. You soon run out of ammunition, but you have thinned the group blocking your path severely.
20
On the shelves, you see antibiotics, bandages, an empty glass, and a rope.
21
You try to grab the bionic weapon that Larry dropped, but getting so close to Subject Zero proves to be lethal and he kills you.
22
You leave the storage and see the exit just a few yards away. You look behind you and see all the monsters that were blocking your path before reanimated and following you. They don't seem to be very fast, so you can probably outrun them, however, you see corpses coming from the rooms around and blocking your path.
23
As you see no way out of here and you don't want to be eaten alive, you decide to shoot yourself in the head.
24
You splash the Abomination's face with the strange liquid, hoping it kills it. It doesn't kill it, but the Abomination does give an agonizing shriek. It will most likely be immobilized for some time now.
25
You completely stop, hoping that the creature doesn't spot you. The disgusting sounds coming from the other side of that shelf indicate that whatever it is is far from being human, and the sounds also indicate that it is feeding. That is lucky for you, if the creature could smell you, the scent of its current meal is probably enough to overcome yours. Eventually, the sounds stop.
26
You shoot the people around you as they charge for you, leaving no one alive. Now you have to make a choice, do you try to find out more about the situation or do you just make a run for it?
27
You try to sneak toward the door, but you underestimate the creature's senses as it kills you before you can even see it. At least it was a swift death.
29
Hoping you can outrun whatever is lurking behind the shelves, you make a break for the door, but the unknown creature kills you before you can even see it. At least it is a swift death.
30
You run for the exit but come across a large number of dead corpses. Remembering what you witnessed earlier, you know that sooner or later, they will stand up and try to attack you.
31
As you know something must have killed those people and it is possibly behind you, wasting no time to turn around and see for yourself, you immediately run away. After you have escaped whatever was behind you, you stop to catch your breath. Now, you have to get out of here, but instead of just running, you could try to find out more about the situation. But that could prove dangerous as you have no idea what is lurking in the dark corners of the lab.
32
You hit the Abomination with the metal plate, but it is ineffective and the Abomination quickly kills you.
33
You enter the seemingly empty room. It seems to be some kind of lab. You notice a closet at the other end of the room. You know you can't ignore the closet, but you also don't know what's in there.
34
The Abomination is eating up an unlucky human, but fortunately for you, its scent overpowers yours and so the Abomination doesn't smell you. It eventually opens and crawls up an air vent and leaves. The coast is clear for you now.
35
You make an attempt to forcefully charge through the group of zombies in front of you, but there are too many and they devour you.
36
You slowly move to see what is making that noise and you see a creature, the likes of which you have never seen before. It has big black and red eyes, giant teeth, razor-sharp claws, and its saliva seems to be possessing some kind of acid as things it lands on start to vaporize. The Abomination is wearing torn jeans, so whatever it is, it seems to be a human, or at least it used to be. This creature could be what started this mess. You could try to kill it, but you have no idea how much it could take.
37
You hit the Abomination with a bucket, but it has no effect and the Abomination quickly kills you.
38
You remember a different way you can go to reach the exit. Through the storage facilities. It is risky, but it is the only path you can take without certain death. You enter the storage and see a bunch of shelves filled with stuff you have no idea what it is for. As you start to walk to the other door in the storage, you hear a strange sound coming from the other side of the shelves.
39
You decide to turn around and you see all the dead corpses in the room standing up and approaching you.
41
You open the closet with your gun aiming toward it. Inside, you find a panicking scientist, who yells when he sees you.
"Wait, you... you're human, aren't you?" he says.
"Yes," you respond.
The scientist looks relieved and stands up.
"Thank you. It seems we are on the same side then. We're going to have to work together if we want to get out of here alive."
"What's the situation here?"
"Alright. I guess you should know."
The scientist says, "For the last few years, we've been working on something called the Reanimator. It's a small symbiotic organism that enters and feeds on our blood. It doesn't drain enough to have any actual impact on people, at least not when it comes to blood quantity. In return, the Reanimator does what it is named after and reanimates dead cells within us. With this thing, the average human age could become more than three hundred years and it would completely wipe out any known diseases."
"I'm guessing it doesn't work quite like you had hoped," you say.
"You've got that right. Subject Zero, the subject we had infected with the Reanimator, seemed to be uncontrollably violent and mutated for some reason. The Reanimator seemed to be greedy and wanted more blood to feed on, but if it killed its host, it would die. So it caused a mutation. Why that is, we have no idea, but the Reanimator took control of the host and mutated Subject Zero to make it capable enough to escape its confinement and feed its hunger."
"It started eating people?"
"Yes. And with it, it contaminated the corpses with Reanimators as well. Now, all the dead people in this godforsaken place are mindless slaves to the Reanimators and constantly thirst for blood. And then there's Subject Zero. He's out there somewhere. I saw him enter the ventilation systems. We should stay away from the vents."
"How do we stop it?"
"In Subject Zero's cell. We have a bionic weapon there that specifically targets Reanimators and annihilates them. It makes the air poisonous for them."
"Wait, there is a monster out there, and you want me to go to its home?"
"Not its home, but otherwise, yes. You can choose to leave, but I'm going to try to kill it, with or without your help."
42
Sacrificial Ending
With the Abomination distracted with the unknown liquid, you turn on the lighter. It takes a few tries to get a fire, but you have enough time with the Abomination in pain. You throw the lighter at the Abomination and it catches on fire. The liquid appears to have been flammable and you watch the beast burn to death. The screams of the Abomination, however, alert every zombie in the vicinity and you are quickly surrounded.
43
You try to shoot Subject Zero, but any bullet that goes through him is ineffective. It does, however, anger him and he kills you.
44
You try to strangle Subject Zero, hoping that he requires air and dies when he doesn't have it. However, if you had paid any attention to what Larry had said earlier, you would know that he only needs blood.
45
You return to the monitoring area, but a large number of zombies approach and they eat you alive.
46
You go behind Subject Zero, hoping that it gives you an advantage. That, however, is not the case and he kills you.
47
You run away back into the storage to escape the zombies, but in front of you is a large, bloodstained creature with razor-sharp teeth and claws. Before you can act, the monster kills you.
48
Heroic Ending
You punch Subject Zero hard enough to get him off the bionic weapon. You grab the canister and activate it. Immediately, you see Subject Zero and Larry, who has just stood up with a Reanimator in his brain, fall down, motionless. You have survived the horrors of the lab and saved the entire earth from a potential doomsday scenario.
49
You sit up as it is probably a good idea to see why the alarm sounded. You see a dozen people running around, panicking, but before you can make out what exactly is going on, a blackout occurs, rendering the monitors useless.
50
You figure it must just be a bird so you decide to go back to sleep. However, you wake up with a dozen people around you that devour you before you can do anything.
52
Subject Zero slowly approaches you, as he doesn't see you trying to do anything. He steps on the glass shards and they drastically stick through his foot. Subject Zero is now screaming in pain. This is your chance to do something, but Subject Zero is standing directly above the bionic weapon.
53
You and Larry enter the cell, finding it empty, much to your relief. Larry approaches a strange canister and takes it. You figure that is the bionic weapon that is going to kill all the monsters. As soon as Larry grabs it, the vent above him breaks and a giant monster lands on Larry. You figure it must be Subject Zero. As Subject Zero is eating Larry, you have to decide what to do.
