The game should be releasing this fall (in the UK, at least), and centers around a rookie detective. He (and therefore, you,) must figure out the circumstances behind the disappearance of aspiring model Betty Blake. The game will focus on the one overarching storyline, but will include other mysteries for you to solve as well (à la Hotel Dusk). In fact, the press release boasts that there are eight different cases to solve.
Also like Hotel Dusk, you'll have to pay close attention to detail so that you can answer questions later (in addition to point-and-click adventure gaming and action-packed shootouts). Check out the new screens in the gallery below for more of an idea of what to expect.
