1: Get The Bunker Open

Use the zipline and throw a grenade at the power symbol to turn on power
Find a bucket and collect irradiated water in front of the blue 115 rock to pour into the 2 funnels in front of each bunker door. Open the door.

2: Electric Shield Bash The 3 Brown Transformer Machines

Build the shield and turn on the trap. Bash the electricity coming from the trap and this will electrify your shield. The time it stays electrified is limited so run to the brown transformers and bash them to turn them on. Locations: Next to the flogger, next to the spike trap, next to the zipline in blue rock area near the fence.

Open the door leading to the basement in the bunker.

3: Talk with the trapped gentleman behind the door and pick up the key card from the machine.

4: Collect 3 Fuses

Fuse 1:

Interact with the computer at spawn. It will give you a color combination. You need to shoot the crystals in that combination. The crystals are the rainbow colored balls ontop of the poles like in Shangri La. The crystals will have a light underneath them representing what color they are. Shoot them in the order the computer showed you. In our game we had to do it twice. After this is done, you will get a treyarch symbol above each one of the crystals.

Now go to pack a punch and collect souls next to the crystal there. When finished, a panel will open below it and give you the fuse.

Place the fuse in the bunker basement machine and talk with the trapped gentleman again.

Fuse 2:

Pick up a sacrificial flag underneath pack a punch. You need to take the flag to 3 out of a possible 6 areas. These areas will have skulls on the ground with a stone tablet. Locations: Next to the blue 115 rock by the zipline, just outside of spawn near the flogger, bottom of the zipline in spike trap area, near the weapon trading table, near the pentagram in the lab, and the other side of the lab with the hole in the floor.

Place the flag at one of these locations. They are in a specific order so you need to find the right one. You will be locked in. Wait about a minute and the flag will turn red. You can then pick it up. It is just timed and no zombies will spawn so you can do this with a crawler.

After youve done 3 locations, go to pack a punch and pack the flag. It will give you a fuse. Go place it in the machine and talk with the gentleman.

Fuse 3:

Find lime colored letters floating in the air and shoot them. There are 6 letters. They spell SPIDER. Locations: Near the flogger, above spawn building, on a grassy hill in the zipline path, in a window near the trading table in the bunker, near the boat outside the map, and near the zipline entrance outside the fence in the spike trap area.

After collecting all the letters, flip the round to a spider round.

5: Kill A Spider On The Pentagram In The Bunker

This will light it up and activate a teleporter. Be prepared. Its a spider boss fight from zetsubou! After defeating the spider, you will be granted perkaholic!

Pick up the fuse on the ground after defeating the spider.

6: Place The 3rd Fuse And Talk With The Gentleman

After talking with him, interact with the fuse machine and the door will open.
