The Hell Apartment's Transformation

“Stay alive, I have to stay alive!”

Everyone who enters this apartment building is determined to survive, but how many can actually make it out alive and escape...? The fifty-year cycle begins anew, but this time, as the cycle starts, the apartment becomes even more dangerous and terrifying.

The residents are tested not only on their wits, but also on the humanity they reveal in passing words. As they lose their humanity and gradually become walking corpses, staying alive becomes an unattainable wish.

Fragments of a Rubik’s Cube! Scattered pages left behind! The sealed apartment! They have sacrificed far too much just to survive. People’s hearts are treacherous, and the road ahead is full of twists and turns... Everything is in The Hell Apartment: Mutation.
