Into the abyss
The most violent criminals are convicted and sentenced to Kletka. Your punishment is to descend into the depths of the Gigastructure while controlling a live and hungry elevator. If you don't want to get eaten alive, never forget to feed it. Kletka is omnivorous, so be prepared to feed it both fuel and meat.
The Gigastructure is an infinitely expanding structure. The corridors are full of traps and abnormalities. Any stop you make may be your last. Samosbor is a weird oddity that destroys everything in its path. This horrific occurrence is feared by everyone since no one has ever survived it. When you hear the siren, drop everything and rush to the elevator as quickly as you can. Kletka is the only thing that will keep you safe from this abnormality.
