If you're a pacifist, don't worry, you'll still be able to enjoy Kojima's Metal Gear Solid: Rising. According to producer Shigenobu Matsuyama, you'll be able to complete the entire game without taking a virtual life, continuing the tradition of non-violence in Metal Gear games.
"I believe that MGS has a key stealth element in not trying to kill anyone," Matsuyama says. "You could actually have a no-kill completion [in Rising]. There will be a lot of mechs and cyborgs, but if you slice them up, that will be considered as a no-kill as well. You'll have the freedom of killing humans, of course, but you can proceed through the game without killing a human being, but slicing up mechs and cyborgs."
I don't have the patience for no-kill completions of any game that offers that option. I may begin a game with the best intentions, but eventually, I'm going to get fed up and empty a clip into a bothersome enemy. I don't feel bad about it either. I will, sometimes, go for the "kill everything" option, and meticulously extinguish the life from everything in a game, whether I need to or not.
Any pacifist gamers out there who plan to play Rising without killing when it comes out?
