the shape of this one
before you start
- the power onthe scientist and the spider cage both wait for it
- an electrified
Zombie Shieldone of the three Masamune parts is behind a cage that only opens to a shocked control panel - the
Skull of Nan Sapwe, for the upgradethe seed planter the third part needs is behind a wall you have to mesmerise
the steps
once the main power is on, a scientist zombie starts turning up around Lab B at random. kill it and take the yellow vial.
the three
KT-4parts can be collected in any order and at any point in the game.with the power on, the cage at Lab A can be lowered. lure a spider inside, then raise it: a syringe goes in and the venom comes out into a vial for you.
the deepest part of the flooded section of the bunker, right of
Mule Kick. it is further down than one breath goes.tipshoot the spores underwater and swim through the burst to get your air back. that is what they are for, and it is the difference between this being awkward and being impossible.
take all three to the
KT-4bench in the bunker and interact with it. it mixes, and you pick the gun up.once it exists, the mystery box can give one to everybody else, so the whole group does not have to build it.
shock the control panel of the cage in Lab B with an electrified
Zombie Shield. get in, and it goes down into a room with skeletons in it. one of them is holding the liquid divinium vial.you only get this wrong oncein co-op somebody has to work the panel from outside: once to send you down and once to bring you back up. alone the cage does both on its own after a while.
behind the blue water pool near Lab A there is a cave sealed with webs. shoot the webs with the
KT-4to open it.kill the giant spider inside, then interact with its mouth to take the fang.
mesmerise the wall right of where the
KT-4plant was with the Skull of Nan Sapwe. behind it is a seed planter.plant a seed there and water it once a round for three rounds with rainbow water, which is in the sewer pipe fast travel, on the right hand side.
tiptake the sewer pipe from the bunker to Lab B and hold interact the whole way through. that is the only reliable way to come out of it with a full bucket.
the Masamune bench is right of the
KT-4one. all three parts on it and the upgraded gun is yours.the boss fight is done with this and nothing else, so whoever is going to shoot the weak points is the one who wants it.
these can be done in any order
