Description:
The Testament of Sherlock Holmes is an adventure game in the Adventures of Sherlock Holmes series developed by Frogwares and published by Focus Home Interactive.
Developers Frogwares have described the game as their "biggest and most
beautiful game". After being delayed from an original 2010 release,[2] the game was released in Europe on 20 September 2012 and in North America on 25 September 2012.[3]

Trailers were shown at E3 2011,[4] with further screenshots being released months later. More screenshots were also posted.[5][6] The game is being developed primarily for consoles, and features a new graphic engine and gameplay mechanics.[7]

Like many other games in the series, the game itself presents an original story and plot that is not based on any of Arthur Conan Doyle's works. The Testament of Sherlock Holmes is set in the London of 1898, with Holmes presented as the main suspect in a case in which he is unable to prove his innocence.
Gameplay:
As Sherlock Holmes in an open world
environment, the player faces an open investigation, and decides which
leads to follow, and which to ignore. Players can handle and inspect
clues, re-enact crimes and use the game’s deduction
system to make their own decisions about the innocence and guilt of
suspects. Different questioning approaches can change the course of an
interrogation by letting the player catch suspects off-guard, or gather
valuable information. And as more events happen that call into question
the nature of Holmes' changing character, you take on the role of Watson and are required to figure out if the famous detective is capable of such brutal actions or if something deeper is at play.

The game uses a new graphics engine, especially developed to display
complex scenes of the game's 19th century London environment, using
hi-resolution textures. The full gore will be shown in its full glory,
unlike the previous game where corpse are seen as drawings and portraits
to hone respect to the real victims. Players have the option of using a
gamepad
while playing, and the control system has been specially formatted for
consoles. The way 1898 London's visuals are rendered a leap over the
locations seen in Sherlock Holmes vs. Jack the Ripper, and toggling
between first- and third-person
views on a console gamepad. There have been a few additions made to the
title's puzzle-centric gameplay, most notably, optional "point of
interest" indicators to help Holmes discover clues, as well as a "sixth
sense" functional that can help Sherlock out when he's stumped. There
are about 20 locations throughout the game, each with unique puzzles,
that range from Baker Street, to London's slums, to a crimson-hued opium
den, and roughly 12–15 hours of gameplay. The gameplay generally
progresses as you gather clues and evidence in every form you're able to
discover, from written material and environmental clues to actual
objects that you gather in your inventory. As you gather clues, you
eventually piece together the evidence to come to a deduction.

A new game engine has been specially built for this new adventure to
immerse players in a believable, realistic and fascinating universe.
Extremely complex scenes will set the stage for the players'
investigations. They can examine every inch to look for clues.The
environments received a great amount of attention to details, and so did
the characters. Using motion capture, real actors now give life to the
new, highly detailed and finely textured models. This technique
increases realism and credibility for each action and every cinematic
scene that advances the story.[8]
The game also benefits from a new light and shadow system, various
post-treatment image effects, a high quality voice over and
cinematographic direction.[9]
