Note: insert designed for game with external box dimensions of 28.6 x 28.6 x 7.6 cm This Campaign 2 insert is designed to be compatible with Mysterium® and the Hidden Signs® and Secrets & Lies® expansions. There is space also for any promo cards you might have. The design provides both efficient storage and improved game play. Many of 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 card decks are all removable from the box and have space for all cards to be sleeved with quality sleeves. There are two trays for the psychic's sleeves and the other irregularly shaped pieces. The other two trays are for the player pieces with separate slots for each colour. These are the remaining card trays which form part of the bottom layer of the insert. The rules board and other tiles go on top of the trays. First go the clairvoyance track and epilogue progress board together with the clock. The clock face needs to be placed face-down so that the dial fits into the top of the card tray below. Next go the rules from the main game and the expansions. Last goes the game screen with the other four progress boards go in a stack next to the screen.This product consists of a flat-pack of 4 Evacore sheets. The trays require assembly which is quick and fun using ordinary PVA glue. Detailed instructions are included in the package.
