An unsuspecting afternoon outing ends in a nightmare: a mixture of chance and curiosity leads you deep underground to an abandoned underground station. Suddenly screams. Cries for help! You follow the sounds... but someone else is following you. There - the glow of a torch! Get away quickly! Where's the exit? And then the water rises. None other than the master of psychological thrillers, Sebastian Fitzek, has come up with this scenario as the setting for his third board game, Underground. And what he has put on paper has been congenially transformed by renowned game author Marco Teubner into a 3D thriller game that is in no way inferior to its two predecessors, ''Safehouse'' and ''Killercruise''. Special game materials such as large puzzle pieces for walls and walkways as well as high-quality acrylic tiles for the water form a spectacular 3D structure that rises up out of the box as the game progresses. The game principle is catchy and intuitive, and each game can be varied again and again thanks to different starting scenarios. The ideal game for all Fitzek fans and anyone who loves well-made board games! How to play: + The players have two tasks: Determine a door code and escape through the exit. + To do this, they place path pieces and run across the playing field with the game piece. + At the same time, the hourglass runs along the edge of the box and puts the players under pressure.
