Horror on the Orient Express: The Board Game New Monstrosities Expansion adds three new monster types to the core game, giving players more ways to customize threats and shape each scenario. During setup, players can select monsters from either the base game or the expansion, allowing for flexible combinations and more replayable sessions. Red Anthramors, Blue Veakhiras, and Green Dronzurs each bring their own behaviors and challenges, increasing tension and forcing players to adapt their strategies. This expansion is a strong addition for groups who want more monster variety and fresh danger aboard the Orient Express.
