The insert is arranged in up to three layers. Note that the character and intruder boards are stacked in the top right corner, and the hexagon room tiles are stacked centrally in the bottom layer.

The component types are split by type organizing all the game components. There is space for all cards to be sleeved and the door tiles can be stored with their bases attached.

The insert includes one large card tray which goes in the base of the box. This tray is removable and also has space for sleeved cards. The tray has space for the base game  cards and those from Nemesis: Aftermath & Void Seeders® expansion.

When packing away the game, first place the game board on top of the trays. Then add the room sheets and rule book on top. This fills the box to the top and allows for vertical storage, as well as easy transport of the game.
