Get your magnifying glass out: there are murders to be solved in Agatha Christie: And Then There Were None, a new adventure game for Nintendo's Wii console. The single-player game was created by United States-based developer Awe Productions and released by Canadian publisher the Adventure Company, having been ported from their original personal computer game released in 2005. And Then There Were None retains the plot from the best-selling source novel, first published in 1939. Eight people are invited to a weekend party at an estate on isolated Shipwreck Island. Through a recording, their mysterious host accuses each of his 'guests' and his two servants of murder - then becomes both judge and jury. The tension mounts and dark secrets are revealed as one by one the number of surviving guests dwindles, following the ingenious plan of the unseen killer. Paranoia kicks in as those who are still alive realise the murderer must be one of their number. Players take on the part of the game's 11th character, the boatman Patrick Narracott, who ferries the guests across to the island. He ends up trapped with them after his boat is scuttled. Gameplay is fairly simple; players can control their character using the Wiimote, with actions that include using a digging motion to unearth clues. But it gets pretty dull after an hour of play. Most of the action entails going back and forth between locations and talking to characters in the hope of finding evidence. Frustration occurs when a player has to backtrack to find something that was missed before. This is an unsophisticated ploy to extend playing time. The game attempts to convey the mood and atmosphere of 1930s England, and it succeeds in most aspects. Unfortunately, there has been no attempt to improve on the original 2005 PC game. The graphics are dated and the characters look stiff. The high points include the appearance of the bright and welcoming mansion, which contrasts with the gloomy stormy weather. The background music suits the ambience but wears thin after repeated play. Multiple endings are possible but this whodunnit would be too mind numbing to play all over again just to see a different outcome. Pros: It's Agatha Christie, the master mystery author. Cons: There's too much back-tracking.
