before you start
- the
Anywhere But Here!gobblegumequipped before you start the game. one of the three cogs is in a room with no door, and this is the only way in. without it in your pack the quest cannot be finished and there is nothing to do but start again - the
Skull of Nan Sapwe - the
KT-4and theMasamune - the
Zombie Shieldand the gas mask - every player's Trials of the Ancients finished
- a bucket and a few seeds
the steps
go down to the living quarters, the body bag room, and find the half a poster on the wall by the purple water. mesmerise it with the Skull of Nan Sapwe and the other half appears.
that is what lets the skull open the map's hidden walls at all.
tipthe two sources put you on slightly different sides of the pool, one saying the wall left of the water and the other saying across from it. it is the one piece of paper either way.
back at the bunker entrance, on your right as you would be walking out, there is a wall left of the yellow danger sign. mesmerise it.
behind it is a broken generator missing three cogs.
use the
Anywhere But Here!gobblegum. it drops you in a sealed room above Lab A with a cog on the floor.take it and either use the gum again or climb out through the hole in the wall.
the three cogs come in any order.
plant a seed, water it with blue water from behind Lab A, and shoot it with the
KT-4, once a round for three rounds. open the pod when it is grown and it might hold a flak shell.load the shell into the Flak 88 at the anti-aircraft platform from the back of the gun. then wait for a cargo plane, which comes over about every two minutes, and hold interact to fire.
the cog falls out of the sky trailing smoke, and lands in one of three places:
- outside the bunker, in front of the
Bowie Knifewall buy - Lab A, by the back staircase up to the zipline
- Lab B, near the meteorite by the green water
you only get this wrong oncethe shell is a chance, not a reward. blue water only,
KT-4only, one shot a round for three rounds, and it still might not be in the pod. plant three at once and treat it as three tickets.tipdo not rush the shot. a miss costs you the shell and the whole plant cycle again; the plane comes back round in two minutes.
- outside the bunker, in front of the
once every player has finished all of their trials, lightning starts hitting the trials platform. stand on it with the
Zombie Shieldout and let it hit you: the shield is now electrified.melee the zipline control panel between Lab A and the docks with it. then ride the zipline with the shield out and melee again while you are directly over the small dock to drop onto it. the cog is there.
tipride it from the docks up towards Lab A and melee straight away. going the other way, a mistimed drop is a long fall.
each player gets three challenges out of a pool of sixteen, and every player has to finish all three before the lightning step will work.
the pool:
- eat a fruit off a plant
- kill eight spiders with spores
- kill three zombies while they are mutating
- thirty kills with the propeller trap
- shoot the heads off five mutated zombies
- get a power-up out of a plant
- kill fifteen zombies that a plant has attracted
- twenty kills underwater
- ten headshots on spore infected zombies
- kill a Thrasher before it enrages
- twenty kills with the fan trap
- water the same plant three times
- water five plants
- shoot five spores
- use a spore to get your air back underwater
- blow up five webs
the rewards are worth having on their own: the top trial gives an extra perk slot, the middle one gives a gun, and the bottom one gives a Max Ammo.
three cogs into the generator behind the wall you opened. hold use and the lift works.
you only get this wrong oncethe lift will take you down now, ready or not. the
Masamuneand the gas mask are what the fight below needs, and going without either is a wasted trip.everybody in the lift. on the way to the arena, the player with the
Masamuneshoots the weak points in the vines blocking the path.in the arena there is a giant Thrasher chained up. the Masamune player shoots a weak point on one of its arms to start it, and then it is a siege: zombies, spiders, Thrashers and ground slams until the next weak point appears. four in total.
you only get this wrong oncethe weak points are on a timer and nothing speeds them up. damage does not bring the next one out sooner, so this fight is survived rather than rushed.
tipfinishing it hands everybody every perk on the map, and puts you back in the arena with zombies spawning, so take the lift back up rather than standing there enjoying it.
these can be done in any order
arrow keys or j and k to move, d to tick this one off.
all of it, done.
