honestly, I was thinking of adding a new punching system, with the addition of blocking attacks from surely one of those white shirts, and adding kicks as well. Not only does this allow for a new way to defend yourself or fight, but kicks will also allow you to break down doors, like the cops who are criminal a criminal or finding a criminal inside his room. This allows the cops, detectives etc. to have a very realistic rp experience, similar to 80s/90s action movies. Also, everyone else can use kicks, but only for a good reason that has a motivation that makes sense.
The fatality/glory kill should be removed because it's too powerful and you risk being killed repeatedly. However, the neck-breaking ability can remain, but only if you're part of a faction. For example: there's a traitor in the family or someone who killed one of your family members. After a couple of minutes, if you don't want to shoot him, you can break his neck. If you think about it, this can be a very realistic rp game, similar to the Mafia.
