This XBox 360 game is an excellent example of the detective game genre. Holmes and Watson have to find and analyse clues, deduce their meanings, outwit people in conversation, and complete many puzzles in order to solve the mystery.
There is an excellent storyline to this game, wherein Holmes himself is suspected of being the criminal mastermind. All of the "chapters" to the story are well thought out, with some good dialogue from the characters to progress the story without too many cutscenes.
The gameplay is very straightforward, and the game helps the player by marking clues that have been seen, those that have not been found yet, actions that can still be performed, characters that can be spoken to. The characters even have a Sixth Sense, as even with the assistance some clues can be hard to find. None of this detracts from the gameplay, in fact it very much helps the story to move along at a decent pace. Deduction boards confirm when you have reached the correct conclusions, and puzzles can be skipped after you have been trying them for a while without success.
Skipping puzzles can lead to missed achievements, but most of the achievements seem to be picked up through straightforward gameplay.
This is an excellent game, fans of other detective games like the CSI series, or the earlier Sherlock games, will find a lot here to enjoy.
