In 1995, Teresa Moontyners, a private investigator, was sent to a remote place in northern Italy on the Swiss border to investigate the disappearance of some researchers. In this place after the melting of some glaciers, a cave was found that, seen from the outside, gave the idea of the snout of a beast, hence the name the lair of the beast. So Teresa was left near the installation from which the latest news came from the research team. Alone... This adventure will take you to the heart of the lair, inside an intricate labyrinth of tunnels, chasms and ancient works forgotten by time. Suspended between snow and fire, solving mysteries and puzzles, as you search for the exit you will discover you are not alone in the caves. An old-fashioned point-and-click adventure immersed in a 3D world, which tells its story alternating between ironic and tense moments, use wisely the resources you will find during the search, can lead you to the desired end of the story, but be careful... just a little distraction will be enough and you will get a more bitter conclusion.
