ZETSUBOU NO SHIMA

Cleanse 4 Skulls by completing 4 Rituals around the map. The Skulls are on a Pedestal to the right when leaving Spawn. Each skull has a symbol corresponding to one of the 4 Pedestals.

During each Ritual, zombies, spiders, and Thrashers will spawn — protect the Skull. After each Ritual, return the Cleansed Skull to its original Pedestal:

• Spawn
• Near Propeller Trap, left of Spawn
• Near Zipline by Docks, leaving the lab power room
• In Laboratory near the KT-4 Tables, near Mule Kick

Once all 4 Cleansed Skulls are placed, lightning will strike and remove the log. Head down the stairs and interact with the skull to start a lockdown. Kill enough Keepers until the lockdown ends, then pick up the Skull of Nan Sapwe.

Collect the 3 KT-4 parts:

• Spider Venom: Lower a cage in Lab A. Lure a spider into the cage so it closes with the spider inside. Raise the cage and grab the Venom after it is extracted.
• Green Vial: Wait for and kill a glowing green zombie near the Green Water. It will drop the Vial.
• Plant: Swim to the bottom of the underwater cave near Mule Kick and grab the plant at the bottom.

Build the KT-4 at the table in the back corner of the Lab near Mule Kick.

Collect the 3 Masamune parts:

• Spider Tooth: Use the KT-4 to disintegrate the webs near the back of Lab A and enter the area to start the Spider Boss Fight. After the boss is defeated, run across the bridge and interact with the spider to grab its tooth from its mouth.
• Blue Vial: After everyone completes all 3 challenges, stand on the Challenge Pedestal to get your shield electrified. Melee the control panel in Lab B with the electrified shield to open the cage. Get inside — in co-op have someone lower it; in solo it lowers automatically. Grab the Vial from the skeleton, then raise the cage back up.
• Rainbow Plant: Obtain Rainbow Water by going into the Sewer System and grabbing water when you see a 115 meteor in the sewer pipes. Mesmerize the wall in the underwater caves (where you got the original Plant) with the Skull of Nan Sapwe. Plant a seed there and water it with Rainbow Water for 3 rounds to grow the Rainbow Plant.

Build the Masamune at the table right next to the KT-4 build table.

Obtain the Skull of Nan Sapwe (see build section above).

Use the Skull to Mesmerize the poster in the Cocoon Room.

Use the Skull to Mesmerize the door next to the Elevator to open the wall.

Obtain 3 cogs and place them in the room behind the Elevator. They can be obtained in any order.

Cog 1: Use the "Anywhere But Here" Gobblegum. This should teleport you to a secret room with dragon eggs — grab the cog on the ground.

Cog 2: Water a plant(s) with blue water 3 times, shooting it with the Masamune each time. If you get lucky, an Artillery Shell will drop from the plant. Load it into the AA Gun and interact again to fire — shoot the plane down when it flies over and aligns with the gun. The Cog will fall somewhere on the map — find and pick it up.

Cog 3: After all players complete all their challenges, go to the Challenge Podium with your shield held out and wait for lightning to strike and electrify it. Then go to either side of the zipline (side closest to the Docks is recommended):

• Solo: Melee the zipline purchase box with the electrified shield to electrify it. Ride the zipline and when over the Docks, melee to drop down. If you fall you will die. Grab the cog on the Docks.
• Co-op: One player rides the zipline. When they are over the Docks, another player melees the purchase box with the electrified shield to drop them onto the Docks. If they fall they will die. Grab the cog on the Docks.

Have everyone enter the Elevator and use it to enter the boss fight. Shoot the branches blocking the way with the Masamune to get past them.

Shoot the 4 branches around the boss when they glow — one at a time. After each one, more enemies spawn and you must wait for the next branch to open up. After shooting all 4 branches the boss fight is over.
