SCP-049

SCP-049 is a plague doctor that wants to rid the world of the "pestilence" in reality, he wants to turn the player into a zombie, you don't need to require a keycard to get into SCP-049's chamber, he will also be a playable SCP soon.

You can use SCP-049's chamber as a way to travel through HCZ, like SCP-939's area, there are no items or keycards you can find in his chamber.

Although he makes SCP-049-2 substances in SCP:CB, he cannot make them in SCP:AB, perhaps it is still a W.I.P.
