I had this idea for a doors entity called "duck":
It's a giant swarm of glowing red bat creatures that appear from the cieling almost without warning (Maybe lights flicker first) and cover the entire room you're in.
When it appears, you have to crouch down to avoid its hitbox. If you fail to do so you will be killed instantly (Possibly with a jumpscare of a red face that bites your head off)
Corpses of players killed by duck have no head

Just a little Idea of mine!
