[wrecked_]

As a small suggestion for reality, you could work off of hitboxes when a player takes damage and use effects based on that.

For example, a player is hit in his left arm. You can use a clcmd (if there is one, never really checked) to change is aiming to his right side and block him from using his left arm for the rest of the round. If you're going to do something like this, though, you need to ask the client upon connection if he/she would be okay with you using clcmds to alter their shooting view.
