Official Description[]

Gerard's retrieve team has successfully reclaimed the research sample from Frozen Terror. And finally, he joined Jim's transportation team. Gerard and Jim recovered damage from repeated battles and rearranged the battle line and started to move to the transaction place to deliver the research sample to a secret client.

Countless pain and troubles are waiting for them while they are making their movement in the polar regions. However, they settled themselves down to achieve their own goals. Who is the secret client? What does the client need from it? Finally, they reached at the transaction area and the thing which welcomed them in the place is...


  1. Jim and Gerrard finally arrive at the lab where they will deliver samples.
  2. As soon as the sample is delivered to the research center that seems to be hidden in the polar region and is about to withdraw, a large number of zombies appear and engage in combat.
  3. Anomalies are witnessed, such as zombies showing interest in samples, and as the zombies attack intensify, a rescue helicopter is called to escape, but fails.
  4. While searching the research center to hold the client accountable, he follows a mysterious voice and engages in a fierce battle with a huge infectious organism he encounters.
  5. CF. It turned out that part of the Rex virus was left behind in a sample Gerrard was carrying. Why zombies react to the Rex virus is still being studied.
  6. CF. The new Gluttony is a boss zombie with a huge mouth that devours everything it sees before its eyes. If you do get eaten, you should quickly install a C4 on Savaging Glutney's stomach and pray that you can escape. In addition, the skin of the Glutonny cannot be damaged by standard firepower, so the weak point on the top of the body must be attacked.

Round 1
Zim msg
Gerrard msg
  1. Jim: Finally, we are here! It is not easy to find the laboratory.
  2. Gerard: I never thought the laboratory is in such a remote area. This place is the best place to hide anything.
  3. Jim: Let's pass the sample to the client and leave this place!
  4. Gerard: Fine! Laboratory! Can you hear me?
  5. Gerard: We've brought the 'item' here. We are in front of the laboratory now.
  6. Jim: Why is there no response? Is it a wrong radio frequency?
  7. Gerard: No, this is the correct one. I also don't know why we don't have response from them!
  8. Jim: Hey, client! We are in front of the laboratory now! Open the door!
  9. Jim: The 'item' that you requested is with us now!
  10. ???: I want you to leave it here and go...
  11. Jim: What? Hey! How can you treat your guest like this?
  12. ???: Okay, be my guest...
  13. Jim: What? Gerard! What is he saying now?
  14. Gerard: Zombies! Countless zombies are coming here!
  15. Jim: How come there are zombies here? Is this your way of welcoming guests?
  16. Gerard: Soldiers, we are having a battle here!
30 seconds after the battle
  1. Gerard: Wait! Their movements look different now.
  2. Jim: What do you mean? Try to kill more zombies!
  3. Gerard: They are attacking the 'item'!
  4. Jim: What? Darn it! Kill the zombies that are attacking the 'item' first!
  5. Gerard: Soldiers! Defend the 'item' from the zombie' attack!
2 minutes after the battle
  1. Jim: Gerard! This will never end like this.
  2. Gerard: The zombies keep coming in! Jim, call for an air support! We are going out of here.
  3. Jim: Roger.
  4. Jim: Eagle One! Can you hear me? I'm sorry, but please come here again.
  5. What's up?
  6. Jim: We cannot move from this place. We are stuck here.
  7. Okay, we'll be there in 1 minute!
  8. Jim: Okay! Let's buy some time, everyone!
After the helicopter has arrived
  1. This is Eagle 1. We cannot see the clock clearly due to the snowstorm!
  2. Jim: Err, they cannot make a landing yet. Let's try our best to buy more time before they can make a landing.
  3. Gerard: Watch out!
Helicopter is shot down
  1. Mayday! Mayday! We cannot control the helicopter! Argh!!
  2. Jim: Eagle One! Eagle One! <grunt>!
  3. Gerard: Jim, are you okay?
  4. Jim: No choice, but we can't really get out from this place.
  5. Gerard: The outer wall of building collapsed while the helicopter is crashing.
  6. Jim: We can enter there! Let's go!
  7. Jim: Payback time to the client!
Entering the corridor
  1. Jim: Darn it! It scared me!

In front of pipe
  1. Gerard: We can only crouch to proceed with this path.
Operating the door room
  1. Jim: The door is not working. Destroy it!
  2. Gerard: I don't think we have enough power to destroy it. The steel door is too strong to destroy.
  3. Jim: Then, explode the door!
  4. Gerard: Fine. Let's plant the bomb in front of the door, everyone.
  5. Jim: It's going to explode. Step back, everyone!
Crane scene
  1. Jim: Oops... this is a dead end.
  2. Gerard: There is another way to go!
  3. Jim: I think we can operate the crane to climb up there.
  4. Gerard: Fine, let's operate the crane!
  5. Jim: Don't even think to jump down, otherwise, you will die.
  6. Jim: Stop the zombies while crane is operating!
  7. Gerard: Let's move, everyone. We'll climb up there!
  8. Jim: Ah!? What's wrong?
  9. Jim: We're falling down!! Argh!!!
  10. Gerard: Are you guys okay!?
  11. Jim: I think so. By the way, where should I go now?
  12. Gerard: There is a gate but, it's stuck.
  13. Jim: There is some kinds of device. Let's explode it!
  14. Jim: Fine ~ this way!
  15. Jim: I don't like a narrow place like this... Hey! What are you doing at the front?! Move now!
Drain pipe
  1. Gerard: It's too dark. I think we can light it up.
  2. Jim: We are surrounded by pipe. We should sit down to move!
Zombie dog appeared
  1. Jim: Whoa, look down! The zombies look strange.
  2. Gerard: Yes, you are right. Their movement is fast and looks dangerous.
  3. Gerard: Be careful and not to fall down, everyone!
Front door
  1. Gerard: I don't think we can pass through it. We must find a way to turn off the steam.
  2. Gerard: Now, we can move.
  1. Jim: The shutter over seems not working.
  2. Gerard: Let's move to the machine room over there.
  3. Gerard: Now, let's move to the shutter.
Container room
  1. Jim: Whoa, I don't think we can survive if we fall down there.
  2. Gerard: I think we can operate the container device to pass through here.
  1. Gerard: Operate the elevator!
  2. Jim: We need to wait till the elevator is arriving! Let's do our best, everyone!
  3. Jim: Come on, everyone. Take the elevator! We are going down now!
  4. Gerard: I don't know what will be there at the bottom.
  5. Jim: No matter what I need to see that client's face!
  6. Gerard: Yeah, me too.
Round 2
  1. ???: I didn't want you to enter inside the dead land.
  2. Jim: Are we still able to contact him? Turn it off!
  3. Gerard: Why is he saying that this place is a dead land? Is it because of him?
  4. Jim: I don't want to think about it. Let's go and catch him first!
30 seconds after boss fight
  1. Jim: Darn it! Is the leather very thick? It's not moving!
  2. Gerard: There are some responses from the shining part at the back. Fire the place!
  3. Jim: I can't see from here. We need to climb up!
  1. Gerard: Let's move to the place where the gas is coming from! Let's go up now!
  2. Gerard: If you don't want to die, use every bomb that you have now!
  3. Jim: The insect is going to suicide! Stop it not to approach here!
Boss death
  1. ???: You are still alive.
