Walkthrough

The solution for this puzzle is different for each playthrough. You need to use the Mutagen Combinator in Mutagen Tanks B to recreate Exitus-1 sequence by combining other mutagen reagents and then combine it into a compound and inject it into the mutagen tanks below, all this you can do with the Mutagen Combiner.

Every mutagen reagent consists of "mutagen atoms" which can be positive or negative. To recreate Exitus-1 you have to add the reagents to the sequence which have same positive atoms and you have to add them in the correct order as Exitus-1. Atoms which shouldn't be in the sequence can be removed by reagents which have the negative atom. When a reagent has an atom which is already in the sequence it won't add to it. See below for an example.

Puzzle hint locations

  • Use the Mutagen Scanner in one of the Hollow Earth laboratories to learn the sequences of mutagen reagents.
  • The computer "log #111251 - M.Brawin" in E. Mali's computer at Caerus Residential Block explaining the basics of mutagenics.
  • The terminal above the Mutagen Combinator in Mutagen Tanks B contains the log Exitus 1 and 2 - Dr. David Gerhoff which explains the role of Exitus reagents and why you cannot just use the Exitus-1 you found to weaken Tchort. Another log at the same terminal contains a list of all mutagen reagents.

Note: all these locations must be powered from Arke Power Station.

List of mutagen reagents

Reagent Location
Icon Mutagen Reagent Exitus-1 Mutagen Tanks A, deepest underground mutagen tanks
Icon Mutagen Reagent Echo-1 Mutagen Tanks B, mutagen storage near combinator
Icon Mutagen Reagent Echo-2 Mutagen Tanks A, in locker south of Tchort's gate
Icon Mutagen Reagent Echo-3 Caerus Residential, Maria Hope's room
Icon Mutagen Reagent Echo-4 Hollow Earth, third building to your right from Caerus
Icon Mutagen Reagent Helicon-1 Mutagen Tanks B, mutagen storage near combinator
Icon Mutagen Reagent Helicon-2 Caerus Residential, Maria Hope's room
Icon Mutagen Reagent Helicon-3 Hollow Earth, building south of Cytosine Outpost entrance
Icon Mutagen Reagent Io-1 Mutagen Tanks B, mutagen storage near combinator
Icon Mutagen Reagent Io-2 Hollow Earth, building south of Cytosine Outpost entrance
Icon Mutagen Reagent Io-3 Caerus Residential, Maria Hope's room
Icon Mutagen Reagent Ovid-1 Mutagen Tanks B, mutagen storage near combinator
Icon Mutagen Reagent Ovid-2 Hollow Earth, building south of Cytosine Outpost entrance
Icon Mutagen Reagent Ovid-3 Mutagen Tanks A, in locker south of Tchort's gate
Icon Mutagen Reagent Solis-1 Hollow Earth, third building to your right from Caerus
Icon Mutagen Reagent Solis-2 Hollow Earth, building south of Cytosine Outpost entrance

Note: You may not need all reagents to synthesize Exitus-1. Exitus-1 itself is necessary so its sequence can be scanned.

Example

Let's assume the Exitus-1 reagent consists of the following sequence of mutagen atoms: GG WQ GP L7 H2 S2 AZ AX CS CN AP W1. And here are all the mutagen reagents which are used to recreate the sequence (not all reagents are listed because only these are needed in this example):

Echo-1: AA S2 AZ VM H2 -AP -AX -BL
Io-1: GP S2 GG AP W1 -DW -PQ
Io-2: L7 H2 WQ AX -CS -W1
Io-3: GG WQ GP AX -VM -AA
Solis-2: CS CN GP AP WQ AX

Left is the reagent added to the sequence, right is the new sequence. In the beginning your sequence is empty.

Io-3    → GG WQ GP AX (the negative atoms are not present because you are creating a mutagen compound which only has positive atoms)
Io-2    → GG WQ GP AX L7 H2 (WQ and AX are not added to the end because they are already present in the sequence)
Io-1    → GG WQ GP AX L7 H2 S2 AP W1
Echo-1  → GG WQ GP L7 H2 S2 W1 AA AZ VM (AX and AP are gone because Echo-1 has them as negative atoms)
Io-2    → GG WQ GP L7 H2 S2 AA AZ VM AX
Io-3    → GG WQ GP L7 H2 S2 AZ AX
Solis-2 → GG WQ GP L7 H2 S2 AZ AX CS CN AP
Io-1    → GG WQ GP L7 H2 S2 AZ AX CS CN AP W1

And that is the same sequence Exitus-1 has.
