How to unlock the Archpocalypse achievement in Monster Train - Definitive Guide

The game has been updated since this solution has been written. Keep in mind that step by step instructions might not be spot on anymore.

This is rather simple with a custom match but to streamline it even more I have created a custom challenge which you can use to replicate this. You can also find Talos during this run for the Ta-ta Talos achievement.

Challenge name: MacroTramadolJumping

---Limbo---
Take Handheld Totem upgrade for Champion
Take Sap Tap artifact

After battle #1:
Take Crypt Builder card

---Level 2---
Take the right path.
Upgrade Crypt Builder with Freezestone and Powerstone.
Take Guard of the Unnamed from the Stygian Banner.

After battle #2:
Take Ice Tornado card

---Level 3---
Tale the right path.
Upgrade Ice Tornado with a Powerstone (+10 Magic Power).
Re-roll and apply another Powersone to Ice Tornado making it 40 damage.
Purge a Train Steward.
From Caverns take "The small shard" and apply it to Guard of the Unnamed.

Battle with Talos
Turn 1
Bottom Floor Lineup: Champion -> Guard of the Unnamed -> Train Steward.
Use Energy Siphon on Talos.
Use Sting on bottom floor.
End Turn

Turn 2
Use Energy Siphon on Talos.
Use Frozen Lance 2x on bottom floor.
End Turn

Turn 3
Use Crypt Builder on Talos

You should get the Ta-ta Talos achievement here.

After battle #3:
Don't take any cards.
Take Fel's Remorse for +1 ember per turn.

---Level 4---
Take the right path.
Take Light's Gift artifact.
Purge 2 Train Stewards.
Take Handheld Totem II upgrade for champion.

After Battle #4:
Take Urchin Spines card

---Level 5---
Take the right path.
Add Permafrost to Urchin Spines.
Re-roll and add Eternalstone to Urchin Spines as well.
Take Precious Plating artifact.

After Battle #5:
Don't take any cards.

---Level 6---
Take the left path.
Don't take anything from Caverns.
Apply Doublestack and Embverstone upgrade to one Energy Siphon.
Apply Surgestone upgrade to a Sting card.
Purge 2 Restore cards.

Battle with Archus

Turn 1
Middle floor lineup: Champion -> Guard of the Unnamed
Use Urchin Spines on bottom floor with Archus.
Use Energy Siphon on Archus.

Turn 2
Use Ice Tornado on bottom floor.
Use Frozen Lance and Stingon middle floor.

Turn 3
Use two Energy Siphon cards on Archus.
Use Crypt Builder on Archus.

This should end the battle and pop the achievement.

Great guide, thank you! Just a heads up that there is a typo under "Battle with Archus, Turn 2." Should read "Use Frozen Lance and Sting" instead of "Use Frozen Lance and Spikes." Not a big deal but could potentially trip someone up.

The @Tan Coul solution worked for the Archus and Seraph for me, the lefts & rights were a bit messed up so pay attention to what you need to be doing on each level.

The OP's seed still works but the actions required are different.

But the same basic strategy applies: get a bunch of spell weakness on the bosses, use saptap for card draw, purge your deck of all but one train steward, high damage spells to nuke the bosses.

I forgot that Serpah has this achievement as well. I just posted the full guide for him as well. Thanks for the heads up!

Great guide. Following this steps, however, left Archos with 170 hp instead of killing him. I don't think I could mess up those three turns, but in any case, if this happens to someone else, Archos will move in one or two turns to the empty top floor and you'll have spell weakness and Crypth builder in hand, so It will be achieved.

As the above solution no longer fully works after the DLC release, I've created StickyBufferLogos that will get this very easily. This will work for Archus and Seraph.
Artifact - Lightstone Casing
Champion - Eternal Flame
Always try to kill your champion each turn to pump it up for the boss, especially in later rounds.
1st battle (The Gathered Clergy)- take subsuming blade, take left path and make it cost less and gain Holdover.
2nd battle (Pyre Absorbers) - take right path to get Waxer Snuffer and Bounty Stalker.
From now on, kill Bounty Stalker with Subsuming Blade at the first opportunity, bringing it back with Primitive Mold for this fight.
Talos - collect Rationing Scales and Fel's Remorse, take left path, upgrade Bounty Stalker with Multistrike, reroll and upgrade again with Endless. Start purging your Primitive Molds and choose Eternal Flame II on your Champion.
From now on, kill Bounty Stalker with Subsuming Blade at every opportunity, rinse and repeat.
4th Battle (Clipped Collectors) - take right path, make Subsuming Blade zero cost.
5th Battle (The Harpy's Guard) - take the left path and duplicate your Bounty Stalker, which should now be over 200*3 damage.
Archus - Bounty Stalkers on the top floor should do it on turn 2.
