The Testament of Sherlock Holmes, and we may have to revise our policy of ignoring any and all residents of 221B Baker Street.
Developer Frogwares have seriously upped the budget for this 360, PS3 and PC release, providing a big bump in graphical fidelity, as you can see for yourself after the break. With a new hint system and a more controller-friendly interface, it's also the first Sherlock game made specifically with console gamers in mind.
Also, Sherlock Holmes dies in it. It's right in the trailer. Go figure.
