It would have to make sure that once the player has >60 damage then all items they put in their hand would be dropped.
After all, you could be holding a pistol to take the 60th point of damage, and then switch to a rocket launcher as your pointless weapon flies away.
And yeah, RTB Prefs to disable. A playertype would be kinda useless, since that just adds more playertypes to a list of many and if prefs work then that's the best way.
