In each of these titles, players are presented with a mysterious story that they must unravel over the course of play. Working together, players explore common areas, talk to people, look for clues, and combine various items to reveal the secret of the story. Depending on what decisions the players make, the course of history changes and there is no going back!

Unlike the EXIT: The Game series, titles in this series focus on the telling and discovery of the story with no time pressure. That said, many different paths can be experienced during play, with more than one correct resolution to the story waiting to be discovered. Each title consists of three chapters, each taking about 75 minutes to play. Nothing is destroyed, so the games can be played multiple times.

In Adventure Games: Grand Hotel Abaddon, you want to discover what strange events are happening in the old building, slipping into your role on the team to follow tracks and decide how the adventure game should proceed.
