Explore places, combine items, and experience tales in Adventure Games, a series of co-operative games from German publisher KOSMOS. In each of these titles, players are presented with a mysterious story that they must unravel through the course of play. Working together, players will explore common areas, talk to people, look for clues, and combine various items to reveal the secret of the story. Depending on what decisions players make, the course of history changes and there is no going back!

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

In Adventure Games: Grand Hotel Abaddon, you want to find out 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.
