I'm currently playing DXSP withou killing anyone. I'm doing fine so far, but I dread the encounter with Anna Navarre in UNATCO HQ. I know it is possible to throw a gas grenade at her to force her to run through the door, bu I have never managed that before, how should you throw the grenade?
Also, is it possible to free Gunther in the first level without hurting anyone. And I mean not even knocking them unconsious.
