I think Black ops should include a feature were you could put a gun to yourself and blow your brains out. Why would this be usefull you ask, its great for escaping being killed or maybe you want to change you class ect. I dont know if it should be a perk or essectial but it would be helpfull. It does add on to your deaths.
P.S it would be awsome looking to for people who like to make cod movies on their capture cards
No. The amount of violence in a game is enough, we're already on the border line. Suicides is just over kill for video games. You might as well include prostitutes and heroin because it was in Vietnam as well, it's that ridiculous.
As far as having an option to "Respawn" like many other games and simply drop to the floor making a groaning noise seems much more reasonable. I'd approve of that idea.
Although I would expect more players would rather try to get a kill in their life span or just use a grenade.
There are ways to do it now. Did it all the time in MW 2 and gave plenty of assisted suicides. Not sure if a kill counted for them though but at least I made an effort to prevent them from getting KSR's.
