This Campaign 3 insert is designed to be compatible with Founders of Gloomhaven®. 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 insert is arranged in three layers. All cards can be sleeved. There are separate trays for the tier 2 & 3 buildings and two trays to split the prestige building tiles. The prestige building trays are designed so it is easy to move the top ones around and see the titles of the other building below. The boards and rules go on top of the trays acting as a lid, allowing the game to be stored vertically. First the adviser/proposal board and the player mats are placed in the recess on the left hand side of the insert. This is followed by the main game board, and then resource tracker board and rules. This product consists of a flat-pack of 6 Evacore sheets. The trays require assembly, which is quick and fun, using ordinary PVA glue. Detailed instructions are included in the package.
