A member of m.e.g has escaped the backrooms only to fall right back into it. Upon arriving he woke up in a void which had two doors, one said BR while the other one said EX, curiosity got the best of him and he entered the EX door. Big mistake. The moment he entered he had to run away from creatures that looked like hounds and skin stealers only they looked much more ominous, the level he was on also looked like level 0 only everything was black and red as opposed to yellow. Two minutes later his dead corpse landed into the m.e.g base through a red portal, some ripped notes were discovered on his corpse and m.e.g scientists soon theorized that harder backrooms levels existed somewhere out there, ones even harder than any of the ones ever seen in the normal backrooms. Soon they decided to name those levels the EX Levels. This accidental return and death marked the discovery.....of the Backrooms true challenge, the EX Levels.
