How to unlock the Old Friends achievement in The Witcher 2: Assassins of Kings - Definitive Guide
**Spoilers**
Old Friends
Finish the game by sparing Letho.
In the Epilogue, you will walk through the city and kill a couple of guys before getting back to the front door. Save your game here. For this achievement, you must talk to Letho as much as you want to learn everything, then select "Let's Finish This" and choose to let him go. When he leaves, the achievement will unlock.
Reload your Save to unlock "Avenger - Finish the game by killing Letho."

As the achievement states, this is at the very end of the game. You will engage in a dialogue with Letho, who will offer a toast to the end of their grievances. After there will be another choice in the dialogue to either fight Letho or to let him walk away. For this achievement (you will absolutely want to do this on Dark), you will need to spare him and let him walk away.
For "Avenger", you will need to kill him. I'd suggest doing this on easy, just because the fight is incredibly difficult on Dark, but it's identical to what it is in Chapter I.
