Our fifth version of Terraforming Mars is in our new plastic line of pre-assembled inserts. It is composed of sixteen different trays and will hold premium sleeved cards. It stores the base game along with the Prelude, Venus Next, Hellas & Ellysium, Colonies, and Turmoil expansions. NOTE: It does this using any one of the Coloines or Turmoil expansion boxes to hold the player boards that came with the Turmoil expansion. If you don't own Turmoil then there is no need to use an extra box. ALSO, this insert will hold the token upgrades provided by Top Shelf Gamer. (The insert does not come with them and they must be purchased separately). They are a great upgrade to your Terraforming Mars game and can be purchased here.
