To get a good ending, the obligatory condition is to keep Alyosha and Damir alive from the Prince's brigade! Alyosha cannot take any damage. The only way! To achieve this, do not touch ordinary people in the Volga, Caspian and Taiga chapters. The playthrough script should adhere to positive actions. Once you kill at least one civilian, the Prince will inevitably lose his life! Do not kill wounded soldiers in the battle for the Lighthouse in the Caspian Sea and do not harm the slaves during the task, where you need to steal a water tanker.
Having received a large dose of radiation in the Dead City, Artem almost dies, but he is saved by Melnik, who sacrifices himself and gives him his antirad. As a result, Melnik dies, but Artem remains alive. He successfully delivers the cure to Anna, who also survives. The game ends with Melnik's funeral. Artyom, Anna and other Spartans get together to say goodbye to Melnik. Artyom is appointed commander of the Order, after which he intends to fulfill the last will of the colonel - to save people.
We allow by our actions to leave the team of Prince Damir. It is possible in the head of the Caspian Sea, where he can stay with Gulnara. Either we kill the unarmed on the Volga, the Caspian or the Taiga, in which case the Prince dies. Well, or let Alyosha get injured in the Taiga. Under these conditions, a bad ending is guaranteed to you!
What will happen:
While searching for a cure for Anna in the Dead City, Artyom dies of radiation. The game ends with his funeral. Anna survives, but she still cannot forgive Artyom for leaving her alone.

How to save Alyosha?
Stick to the tactic of good deeds! Do not kill any pioneers or pirates. People who do not have weapons must live without exception! The finale of such actions will be Olga's gratitude.
Throughout the Caspian Level, you will meet slaves, and so, they cannot be killed, even those with weapons! The maximum damage that can be done to them is a stun. If these conditions are met, Damir will remain in the Prince's team until the end of the game.
How to save the Prince?
First: Save all the slaves in the Caspian.
Second: Find and bring the guitar to Stepan
Third: Do not kill unarmed sectarians and civilians.
Fourth: Find and bring the bear to Nastya.
How to save the slaves?
The slaves are inside the ship of the Oilmen's gang. His location will be indicated by Anna. On the ship, go upstairs, and going into the captain's cabin, find the exit, near which you will find a special lever. By pulling on it, all the cells will open and the slaves will be free. Then the gate will close.
