TBH I just borrowed this from Operation Flashpoint Dragon Rising, which you can check out if you wanna see what I mean.
-Shooting at someone in the head that has a helmet(military helmet) with a low caliber weapon should induce some sort of concussion, and should add a weird effect as well as reduced weapon stability
-shooting in the arm should make actions like healing reloading, etc slower, and also reduce weapon stability
-shooting in the leg should slow someone down, and shooting both legs should require someone to crawl(stay in prone) until they heal themselves.
-if someone gets hurt but isn’t hit in the head, blown up, or damaged too much, they should lay on their backs with a wounded animation
-the player should be prompted to commit suicide, and can still use the walkie-talkie to communicate to their friendlies that they are wounded
-a marker should appear on the person, and on the map for those who are in the same group so they can still heal them and/or know they are down
-other players should be able to shoot them to finish them off, or can heal them with a medkit, which further encourages someone in a group to be carrying lots of medical supplies, which in turn encourages better teamwork
-What do you guys think of?
