Price, Ghost, Soap and Gas

A post-apocalyptic zoo is a living hell. Team 141 makes its way to the server room through the orangutan enclosure. Dozens of eyes in night vision devices monitor every movement.
Gas whispered:
— Bravo-6, at twelve o'clock, on the ropes. There are at least five of them there. Large specimens.
Price replied:
— Don't look them in the eye. Just walk. Slowly.
You move in a tight diamond formation. You're in the center, behind Soap and Ghost. Suddenly—BAM! A huge chimp pounds the iron. The group instantly takes up a circular defense, covering you.
Ghost threw at you:
— Watch your rear. They're coming from behind.
The gorilla leader blocked the way. Price commanded:
"Soap, flashbang ready. If he moves, don't shoot, just blind him. We don't need the whole pack on our backs."
You pass a meter away from the alpha. Soap pries the door open with a crowbar. Makaka jumps at Gaz, but he knocks her down with the butt of his rifle.
Price shouted:

• Soap, come on! Everyone inside!
  You burst into the building. Ghost slams the door in the leader's face. Outside, dozens of paws pound the metal.
  "Calm down," Price exhaled. "Gas, check the lock. Soap, Ghost—the corners. We need the server rooms on the second floor."
  Ghost removes his hand from your shoulder, raising his rifle.
  "How are you, soldier?" he snapped at you. "Don't freeze. The walls are thin here."
  The group moves deeper over crunching bones. A rustling sound is heard from the ventilation.
  "The little bastards are already inside," Soap whispered. "Captain, if they chewed through the wires, the disks are doomed."
  “Then get moving,” Price snapped.
  The second floor smells of predator. The door to the server room is open.
  "Found it," Gaz waved his hand. "Soap, cover me. I need three minutes to retrieve the blocks."
  The rumble outside subsides. A vibrating hum echoes through the silence of the server room. In the beam of the flashlight, a huge gray tiger with a chain around its neck appears. It slowly rises.
  "Your mother..." Soap whispered.
  "Back," Price commanded. "Back slowly. Accelerate, discs canceled, let's go. Soap, flashbang ready in case he jumps."
  Ghost shields you with himself.
  "Get against the wall!" he barked at you. "Price, this thing's faster than it looks!"
  The tiger roars and takes a step
