Agatha Christie: And Then There Were None

Agatha Christie: And Then There Were None, often shortened to And Then There Were None, is a point-and-click adventure game from 2005. AWE Productions handled development, while The Adventure Company published it for Microsoft Windows. This title launched The Adventure Company's Agatha Christie series. The gameplay centers on a detective murder-mystery. Nine people, including the playable character Patrick Narracott, gather and travel to the fictional Shipwreck (Soldier) Island. Once there, two more characters appear on screen, and the story proceeds from that point.

The game largely follows the core plot of Agatha Christie's 1939 novel of the same name. Key differences involve the addition of Patrick Narracott as a playable figure and the availability of multiple endings. To strengthen the link between the game and its source, the North American PC release included Christie's novel. Two further games followed: Agatha Christie: Murder on the Orient Express and Agatha Christie: Evil Under the Sun. Because these were based on their own novels, their stories had no connection to this first game. Critical response was divided. Some reviewers considered it a faithful adaptation of the book, while others saw it as a very poor adventure game. Several critics strongly faulted the character design and graphics for being outdated, but others commended the character dialogue and engaging story.

Gameplay follows a point-and-click adventure format from a third-person perspective. Interacting with the world mostly involves questioning other characters, gathering items, and combining them. An inventory system, with screens that hold up to twelve items, lets the player carry objects. New items fill the first empty slot, and they can be examined or combined at any time. The cursor changes context; it becomes a rotating gear when hovering over something the player can use. The game uses a 2.5D graphics engine, mixing pre-rendered backgrounds with 3D-modelled characters.

The game splits into ten chapters. Each new chapter begins after a specific trigger event. The developers made sure nothing essential could be missed as the player progresses, though many sections are optional and side-quests can be ignored.
