Logistics is the 4th level, and is the second-to-last floor.
Quite high. Due to the size of most rooms, expect heavy spawn rates of turrets, and many high-level bots.
One item of note is a unique boss, The Egg Scrambler.
Logistics is composed of the spawn, three (possibly four) large random rooms, and the boss room.
It has a green color scheme, with the walls appearing to be made of circuits.
