the time, and a rating of "hard", come from Mined Games at COD Zombies Guides. the pips are our own estimate, scaled against every guide here.

the steps

1. 1

   build the guillotine

   #

   opposite the side of the saloonanyone

   four parts:

   • the satellite dish, on the top balcony of the saloon, on the side nearest the guillotine bench, by the fence
   • the spool of wire, in the corner of the gunsmith room downstairs, near the catacombs entrance
   • the crystal, in the catacombs near the LUNGER UNDERMINES sign: up the railing from the saloon, left, left again, jump the hole, in the debris straight ahead
   • the antenna, downstairs in the barn towards the catacombs, in the far right stall

   both sources list the same four in the same four places, and the bench is parallel to the right hand side of the saloon.

   you only get this wrong once

   some of these parts also build Maxis' gallows, so this is where you commit. building the guillotine is choosing Richtofen for this game.

   power four red orbs with the Paralyzer

   #

   the alley, the church, the tunnels, the mazeone player with the `Paralyzer`

   hold the Paralyzer on each of four red orbs until it turns white and dings:

   • the alley between the saloon and the candy shop
   • the graveyard left of the church entrance, behind a rock
   • the tunnel system above the town, near the LUNGER UNDERMINES sign
   • behind the witches' mansion, in the foliage before its entrance from the maze. the wiki says the right hand side here and says the left on Maxis' side, for what reads like the same spot, so sweep both
   you only get this wrong once

   the two sources do not agree about this step, and it is the only place on this map where they disagree about what to DO rather than about where something is. the wiki has the two sides use different tools: the Paralyzer to power the orbs for Richtofen, the Subsurface Resonator to break them for Maxis. codzombiesguides has it as one shared step before either side starts, with the Paralyzer on both, heating each orb until it turns white and dings. take the Paralyzer either way and listen for the ding. if the orbs will not take it on Maxis' side, that is when the Resonator is worth building.

   knock the lantern down and feed it

   #

   the courtroom, then the haunted mansion, then the gunsmith roofone player

   a purple lantern floats from the courtroom to the church, or from the courtroom to the jail cell. time a grenade to knock it out of the air and pick it up.

   then kill at least ten of the ghosts in the haunted mansion while holding it. when it has enough souls, put it on the symbol on the roof of the gunsmith shop.

   you only get this wrong once

   miss it and it goes. leave it on the ground too long and it goes too. a cooked grenade is what both sources call for, rather than a thrown one.

4. 4

   decode the wall and hit three signs

   #

   the gunsmith wall, then the tunnelsanyone

   a code appears above the symbol on the wall. it is a tic-tac-toe cipher, and decoded it names three of the five tunnel signs:

   • DRY GULCHER SHAFT
   • LUNGER UNDERMINES
   • CONSUMPTION CROSS
   • GROUND BITER PITS
   • BONE ORCHARD VEIN

   all five are seventeen characters long and all five start with a different letter, so only the first letter of each has to be decoded. hit the three it names with the Galvaknuckles or the Bowie Knife. order does not matter on this side.

   the three are picked at random each game. hitting them makes the wisp appear.

5. 5

   walk the wisp to the guillotine

   #

   the tunnels and the towna player with `Vulture Aid`

   the wisp is invisible without Vulture Aid. walk through it to move it: it vanishes and reappears somewhere else, visible through walls.

   where it goes first depends on the last sign you hit:

   • G or B: in front of that sign, then the courthouse by Speed Cola, or the tunnel between the G sign and Quick Revive
   • D: in front of the sign, then the tunnel between the L and C signs, right of where the guillotine crystal spawns
   • L: in front of the sign, then the tunnel, next to the C sign
   • C: in front of the sign, then next to Quick Revive

   after those first hops the route is the same every game, with small variations.

   you only get this wrong once

   you have fifteen seconds to reach it each time. miss it and it fades, and you are back at hitting the signs.

   tip

   codzombiesguides adds something the wiki does not: keep zombies dying near the wisp to sustain it, and they glow when it is feeding. that is how Maxis' side works, so if the wisp keeps fading on a route you are walking fast enough, try bringing a crowd with you.

   find the switch in round infinity

   #

   on one of four bodies, somewhere in townall four

   put a Time Bomb on the guillotine bench, have all four players stand round it, and set it off. you go forward to Round ∞: black and white, and the zombies barely die.

   you have sixty seconds to find the switch. it is on one of the dead bodies of Misty, Marlton, Samuel and Russman, which spawn at random from:

   • directly in front of the guillotine, and just past that under the G of GUNSMITH
   • in front of the saloon steps, and left of the gunsmith entrance
   • the crevice behind the barn and the gunsmith house, where the Navcard table parts are
   • the alley between the bank and barn walls, against the bank
   • in front of the jail house entrance
   • between the general store and the box spot
   • right of the candy store entrance coming from the courthouse
   • between the big rock by the gallows and the candy store awning, by the arrow sign
   • behind the rock left of the church, where the red orb was
   • just past the church entrance, near the workbench
   • against the rock between the witch's house and the debris in front of it, half sunk into the rock

   sometimes only two or three bodies spawn. put the switch on the guillotine once you are back: it cannot be fitted during Round ∞. both sources count thirteen possible places and sixty seconds.

   you only get this wrong once

   fail and you need another Time Bomb. Arthur can be fed candy next to a Bonus Points drop to turn it into something else, which is one way to buy at a random powerup; otherwise it is the box or running rounds for a Max Ammo.

   tip

   everything you spend in Round ∞ is refunded when you come back, so use the Monkey Bombs and feed Arthur freely while you are in there.

   four coloured levers in the maze

   #

   the mazeall four

   four gates with red, green, blue and yellow levers. all four have to be pulled in the right order, and there is nothing to read it off: it is trial and error.

   no lever sparks until all four have been pulled, and then only the ones that were in the right place spark. to reset, pull all four, get everybody back to the main area, and run through the mistress's house together.

   you only get this wrong once

   yellow does not always spawn on a gate. when it does not, it is hidden in the hedges near the fountain.

   make a wish and shoot everything

   #

   the fountain, then four places at onceall of you

   use the fountain in front of the church and the mansion to make a wish. metal targets are struck out of the ground by lightning in four places, and every one has to be shot before any of them goes:

   • beside the candy store and in front of the courtroom, 20 targets
   • the left side of the mansion, in the windows, 23
   • inside the saloon, 19
   • the fourth is where the two sources part: the wiki says by the jail cell, 22 targets, and codzombiesguides says near the mystery box. only the wiki gives any counts at all, so treat all four numbers as one source's

   that is your side of Mined Games done, and everybody gets every perk for the rest of the game. the story has one more piece, and it is the endgame on this map.

   tip

   the Paralyzer works on the targets and is the fastest thing here. give Arthur candy near a crawler first so the round cannot end underneath you.
