Weapon Idea:
Hangman's Noose
If ragdoll is placed under and triggered within a small radious, it will be attached to the noose, and either die instantly, or slowly die.
Add a upgraded medigun, let's say I throw the doll at a wall taking it's arm off. If I use the upgraded medigun on it, it'll force the arm back on, stop bleeding, and return to full health. Plus, it'll restore health fast. It is also automatic.
There should be bruising. For example, there is something that hits him hard, but is not enough to make him bleed out or be torn apart or whatever, it just discolors, doing damage like a bruise would do.
