T1:
Complete all, since they're unlocked by default
Farm Beach and Lookout
- Obtain Arid Lake and Pen
    - You can now unlock Flooded Mines, Marshes and Alleways

T2-T5:
Farming Flooded Mines, Marshes and Allways
- Obtain Cells, Leyline, Burial Chambers and Port
    - You can now freely unlock all T2, T3 and T4 maps
    - A small note about unlocking T4 maps; Aim to unlock Chateau first as it's the adjacent map for Toxic Sewer which we need to farm soon
A note about T3:
- It is adviced that you first unlock Flooded Mines and maybe Alleways, as it's 1/3 chance to find the last map you need to farm from those maps
- After that unlock Marshes, as it's 1/2 chance that the +1 map is Burial Chambers, so finding the other T2s won't hurt your chances nearly as much as finding Marshes while trying to look for the last 3rd map from Flooded Mines or when looking for Port

T5:
The first T5 map you should unlock is Toxic Sewer, as the next hard-to-obtain map is Phantasmagoria
Farm Toxic Sewer untill you obtain Phantasmagoria

T6:
First a note about Shaper/Elder influence:
As Elder influence starts at the earliest from T6 maps, if you have Shaper influence in your Academy when you run it and you have completed enough Shaper influenced maps,
you will get your first Memory Fragment and Elder influence will start in Academy and some of it's surrounding maps
- If you really wish to start Elder influence in a different corner of the Atlas, you can run a T6 or higher map in a different corner, however it will hurt your progression a bit at this point
Unlock Academy
- After you unlock Academy, you can unlock rest of the T5 maps
- Farm Academy untill you obtain Gardens

T7:
After obtaining Gardens, unlock Underground River
- After unlocking Underground River you may unlock rest of the T6 maps
- Farm Underground River untill you obtain Mineral Pools

T8:
After obtaining Mineral Pools, unlock Courtyard
- After that, you can unlock rest of the T7 maps
- Farm Courtyard untill Temple

T9:
After obtaining Temple, unlock either Estuary, Tower or both, as they both are adjacent to Shipyard
- You can unlock rest of the T8s after that
- After obtaining Shipyard, unlock rest of the T9 maps

T10:
Unlock Bog
- Farm untill you obtain Primordial Pool
