Insert compatible with Nemesis: Lockdown, and includes space for the Nemesis Lockdown: Stretch Goal content. The design provides both efficient storage and improved game play. The trays can be utilised during the game, and they greatly aid set-up and clear-away times. The rules and boards act as a lid on top of the trays.

The insert is arranged in up to four layers as shown below. Note that the character boards are stacked with the card holders and scanner in the top right corner. The hexagon room tiles are stacked centrally in the bottom layer.
