Is it possible to make a door that can only be shot open by a shotgun, but instead of opening, the door breaks down?

Yes, make the door be a func_physbox and have it fire an output when it takes damage. Fire the output to a powerful phys_impact aimed at the door.

No, damage dealt is weapon inspecific.

Why not just use a func_breakable?

K, thanks for the help, works great!
