The guide is currently representative of the most recent patch 0.90v.

....And they've changed the UI again, so i have to update all the pictures again along with the newly added companions

New UI



Recruitment/Upgrading

Recruitment has changed. It appears you now buy a type of troop and that troop levels up. They dont upgrade into a new type i.e. Militia upgrading to Rifleman. Instead they level up and their stats increase accordingly.

Each have their costs and you can buy them with or without equipment from all towns, villages and mercenary camps

Found randomly in the bar of each town. They cost varying levels depending on their skills. I'm not sure whether Companions are randomly generated or specific builds. Given each one has a story that you can ask about (increasing familiarity), i'm assuming they're not random

You can level your companions up in the companion tab

Anastasia
cost $2000


Ivan
cost $5000


Ludmila
Cost $3000


Maxim
Cost $5000


Yevgen
$5000
