In news that apparently somebody asked for, it has been confirmed that you can complete the upcoming game CyberPunk 2077 without killing a single person/robot/part person part robot...I'm not really sure what they identify as in CP77. Moving on!
According to Pawel Sasko, the lead quest designer for CP77, you can get through the whole games without killing anybody stating that there are weapons designed to kill and others will be non-lethal.
The decision to add non-lethal options into the game came after a survey CD Projekt Red handed out at E3 2018 with multiple ideas being asked about. The option to get through without having to kill was wildly popular with the survey takers so it was added to the game.
Now that's listening to your fans!
