Use quick saves
In case you mess up you can always load back

Try to knock out as much enemies as you can

If they start shooting you, you are allowed to shoot them back(kill them) wont endanger the results, but in some chapters you must not shoot them at any
circumstances only knock them out,and those chapters are- The Taiga(Pioneer´s) and The Caspian(Slaves)

They are free to kill, won´t affect the outcome of the ending

The reason for keeping these 3 people alive(down below), you´ll find out so i don´t spoil out too much of the game´s story

Trough combat if enemies surrender DO NOT kill them, just knock them out

White/Black screen Flash


Every time you did a good thing you will notice a white flash on your screen

On "The Winter" chapter there is a slave captured in a cage near the train track

Black flash is just the opposite i just said

VOLGA CHAPTER
How to save Duke so he won´t get wounded and die-

Do NOT Kill anyone at church once u get there,escape stealthy, you can knock out people but do no stealth kill them or shoot them!

No killing when stealing a boat!

Once you stole a boat youre gonna immediately continue to the bridge gate where the chapter ends, and there comes the most important part. When you will come to the bridge duke will want to compete who will be the first at the top, that doesn`t mean you have to rush trough! Same thing, do not kill anyone cuz if you kill atleast one guy ,Duke dies, captain commands to shoot!

CASPIAN CHAPTER
Damir joins Crew

No killing the slaves anywhere on the map, respect them cuz they don´t have choice they´re fighting for a cause that dont necessarily belive in.

Get a photo from a bunker for GIUL ,and you´re gonna find that when you´re trying to get to the ventilation shaft you´re gonna climb trough that in order to get to a map room, once you get trough, there is a room with a dead body holding a photo.

Anna gives you side missions

Oasis - Top left corner of the map
You have to do it stealth to free one slave and steal a truck with water tank, after that you will get ambushed outside, you´re free to kill.

Shipwreck

Go there and kill everyone, once you do that you´re gonna go to the control tower and pull the switch to free 3 slaves at the bottom, and one more switch at the top close to the cage where slave is inside,ride down the zipline, you´ll see the switch behind you on the metal pillar

When you go into the sewer damir opens it for you you have to go stealth again or knock out slaves

You literally need to release all the slaves and not kill them in order for Damir to join the team
You´ll know he joined your team if he hops on the zipline with you.

On other 2 side missions its just important that you don´t kill the slaves

TAIGA CHAPTER

Dont hurt pioneer´s, consider stealth

You´ll know the result, while ziplining down if he passes out you failed, if he makes it down on his own 2 feet then you succeeded

If you get trough the whole chapter unoticed without killing anyone you will get a achievement "A Forest Child"
