Nier: Automata

City Ruins: Deep Cave

An optional side-area that becomes available upon completing Emil's Memories.

You have to talk to Emil near Desert: Camp after every time you use chapter select to unlock the door to his residence.

The cave can be reached by entering a pipe in the upper northeast corner of the crater (where the edge of the crater is closest to the overpass), and taking the elevator down.
