Metro 2033 Good Ending Guide

To get a good ending in the game, you need to follow the steps below.

• Play as stealthy, don't kill anyone just knock them (you can kill bandits)
  ⤷ If you are in a Machinegun you can kill the enemy
  
• If someone surrenders, just knock or pass
  
• Give bullets to the poor people
  
• Listen to the dark one, go to him when he calls you
  ⤷ Never shoot at him (At the end of the game, Hunter will give you a gun, there you just have to shoot)
  
• Some mutants only want to protect their own family, don't attack them
  
• If you do something good and they reward you, don't take it.
  ⤷ In one chapter you will save a little boy and his mother will give you bullets.
  
• Stop at some places and listen to NPCs, their stories, etc. (enemies too)
  ⤷ At the beginning of the game, your father will call and there is a hospital, a woman will talk and you have to listen to her.

• Don't forget to shoot with the revolver that fires missiles towards the end. (If the missiles are fired directly then it's a Bad Ending)

• You will also earn the achievement "Enlightened" when you complete the game.
