Official Description[]

Norman msg

Jim, I advised you before but now you had ruined all the work by yourself! If you are really the leader of Red Lizard, you shouldn't lean to one side. I couldn't do much things due to your selfish decision.

Why this situation turns out like this? It is pretty bad. By who? And why? Since when it started to be wrong, it is already too late to blame each other. Don’t forget this although we are not in the same team anymore after we had decided to walk in our separate way. Soon, you will get a clear thought of knowing which decision is right and wrong.

- Norman has stopped in writing a letter to Jim when the guards entered and he left the house immediately after receiving an urgent report from them.


  1. Norman was Jim's subordinate, but joined the Vanguard Company, and in exchange for his betrayal, was given the position of Commander in Chief.
  2. In order to be recognized for his status, he independently conducts Dr. Rex's research, but the result is a virus leak due to a virus mismanagement.
  3. Norman, while working in his office, heard about a virus leak from bodyguards and tries to escape, but the Vanguard Company lab is already full of zombies.
  4. Even the Ospreys, the last remaining means of escape, is sent away due to the betrayal of his colleagues, and he remains completely isolated in the panic room and asks the AFC crew where he usually trades for his rescue.
  5. CF. Norman was the headmaster of the red lizard. He is very greedy for money. He doesn't understand Jim's refusal to accept the request of the giant company, the Vanguard Company, and in the end, to satisfy his greed, he betrays the Red Lizard mercenary and sells his garrison to the Vanguard Company.
  6. CF. Fallen Titan is an infection of a new Titan being developed by the Vanguard Company. It was larger than the existing Titan, and it was manufactured as a fusion weapon rather than a simple gear. It is known that there are various types of weapon loading depending on the type. However, after being infected with the virus, it begins to act independently without carrying out the given commands.

Steel Door Open
  1. The zombies are migrated to here. That’s very annoying!
  2. Be careful when you walk as there is electricity overflow on the floor unless you want to be barbequed.
  3. These zombies are quite strong. Be careful if you don’t want to become as part a part of their meal!
  4. It was expensive to hire those researchers but my money went wasted like this...
  5. Shoot all of them! Let’s move to the hanger!
Monorail Zone 1
  1. This is bad. We can only move to the next zone by blocking the electricity.
  2. We should investigate about the reason why the electricity control device in the Laboratory has a problem.
  3. Let’s detour and head to the Electricity Control Room!
Electricity Control Room Entrance
  1. It seems like the highly-paid researchers have been killed while evacuating to the ventilation area..
  2. At least I don’t need to pay for their gratuity. I believe they have insurance covered. Anyway we should move now!
  3. Destroy every electricity control device to block the electricity!
Aseptic Room
  1. Is that security door locked? Oh it can be opened.
  2. There will be a researcher’s card key somewhere. Search it now!
  3. Hmm, this aseptic room is so bad as I thought.. We should close this place as well.
  4. Yes. Those dirty things need to disinfect..
  1. Umm. That zombie is... Yes! It’s the 'Siege'-type as I read from the record!
  2. Use the large space to fight against zombie wisely!
Laboratory Room
  1. The electricity has been cut off so the door doesn’t work properly.
  2. If you destroy all the four cylinders that contain Zombie Virus, the entrance door will open!
  3. Announcement: A poisonous gas has been activated! Researchers, you should evacuate now!
  4. Have you exercised CBR training before? Wear your gas mask and evacuate from here as soon as possible!
  5. This entrance door has locked.. You should destroy all the cylinders like what you did just now!
  6. This time the cylinders don’t look easy to destroy due to its thick-glass wall.
  7. Destroy it using a cylinder explosive device. Do it right now!
Raiser Defense Room
  1. The device didn't betrayed us. It works very well..
  2. A laser defense system that has been prepared for an emergency situation is in operation now!
  3. You will be barbequed if you touched the laser, so watch it out!
Monorail Zone 2
  1. Umm.. It’s here again? I can’t find the way out.
  2. Let’s secure a shortcut for an emergency case!
  3. Listen to me, those soldiers who will join from the back line.
  4. I will open the shortcut, so look at the coordinate to join us!
  5. Fine. Now, we should move to the missile hanger to secure the escape route. Hurry up!
Missile Hangar Entrance
  1. I heard that the engineers have been infected from this place.
  2. I don’t need anyone who has been infected with the virus so kill everyone!
  3. Don’t hesitate and remove all of them!
  4. We delayed too much time here. Let’s work together to remove them quickly!
  5. Target at the head! I don’t believe your shooting skill is bad like this.
Ventilation Facility Passage
  1. This way is blocked! Hmm, this is not good.
  2. You are quite skillful! At least, I don't feel that bad for paying you just for that!
  3. Let’s go through the large ventilation facility. Plant the bomb.
  4. I hope we are in the right track.
  5. Don’t relax yourself yet! You can die anytime once you relax your mind!
  6. I wonder what kind of Zim's decision that would make in such situation.
  7. I guess he had made a wrong choice and the situation becomes even worse.
Ventilation Facility
  1. This place looks safe.
  2. The operating ventilation device’s temperature is high! Watch out and try not to burn yourself!
  3. We can make use of the strong wind from the ventilation device to fly and escape from the zombies.
  4. The gas leaked from this place. This place might be the beginning of everything.
  5. We have some difficulty in moving due to the strong wind from the extractor fan. Let’s quickly move to the opposite direction of the wind!
  6. Darn it! What is this?! Zombie dogs?!
  7. They did not take care of those guard dogs.
  8. They can also spread the Zombie Virus. Kill all of them!
  9. They are not the guard dogs anymore and they had became monsters now! Don’t look down on their ability!

  1. We can escape from here once we passed this place and go to the aviation shed to take the Osprey. Hurry up!
Aviation Shed
  1. Hey! Stop there!
  2. How dare you leave your Assistant Chief of Operations behind!? I will definitely find you to take on the revenge.
  3. Don’t swing your emotions. Let’s move to the panic room, everyone. We can open the entrance of the panic room by destroying all the security turrets in the aviation shed.

  5. I will request for support to AFC in the panic room.

  6. Oops.. The new Titan is also infected!
  7. It’s great. We would able to use it as a living weapon.
  8. Oh yeah, this is not the right time. I don’t think this will be easy to deal with it. Please be prepared, everyone!
  9. That type is specialized in melee attack!
  10. That type is specialised in long-range attack!
  11. Did we manage to defeat all of them? Now, we can take some breathe and wait for the Rescue Team to save us.

  13. Darn it! They are calling for the other zombies again!
