shadow challenge

Not much is known about the void (sovereign but he's kind of cool or something, and one of its forms is a pitch-black wall. The void will appear 10 rooms behind. If a person opens a door, the void will consume the room in front of this wall . If a person touches the void, they will instantly die)

If you have died from any of the above entities, then you will encounter one mysterious entity Overseer is a entity that he is responsible for the creation of the entities within the shadow challenge, hes also responsible for the revival of d-180 now known as SHA-180. Overseer won't help in any way. He will sarcastically talk about you and your deaths and openly mock you, and will only yapping how proud he is of his creatures, if you die at the hands of an ordinary uninfected entity, he will irritably and sarcastically say that they are imperfect or something like that, He will also ridicule you for your deaths
Overseer is the result of a willing humanoid being a test subject to the shadow infection.
Said humanoid gained a lot of power from the infection, creating Overseer
He doesn't like Void and he'll tell you not to die from Void because Void has a "big ego"

The remaining infected are (they purple or black too) include : SHA-30 , SHA-35. SHA-55 SHA-60, SHA-85(will spawn in front of the main room's door and wait there for about 2 seconds before teleporting away. After 18-22 seconds, or after the door is opened by the player, SHA-85 will either rush from behind the void wall, or from behind the main room's door ,in short walks back and forth sometimes it can summon SHA-200), SHA-120(he walks back and forth and leaves behind dark puddles that cause a shadow plague effect), SHA-140, SHA-150 SHA-180(it has a chance to summon either SHA-1 or SHA-2) , SHA-200 (if you hide from him, then besides the locker, you will die because a minigame is about to happen in which he will try to break into your locker)

The action takes place in section A (abandoned office) There are also other sections - D section, M section from there some entities

The Shadow Challenge is a Secret Challenge, that makes every room purple and make some entities infected with the shadows, 2 of them being forced to spawn atleast once (SHA-85 and SHA-200). it also has 3 exclusive main entities, those being SHA-1, SHA-2, SHA-3 and SHA-4 (it summons shadow entities)
