What a cluttered field it's become, eh? In this instance, the one-man project Bohemian Killing [official site] tells a tale of Alfred Ethon, accused of a grisly murder in a steampunk 19th century Paris rife with racism and tension. It then sets things in two time periods, the present day of the courtroom in which you are trapped, surrounded by the evidence against you, building your case, and working out what approach you'll take, with flashbacks to the year previously when the crime was committed.
Apparently decisions made in the flashbacks will affect how the court case goes in the future, which all sounds potentially very exciting. Quite what this trailer has to do with any of that is mystifying, looking like a weird tech fly-through with some dodgy voice acting.
One of those voice actors, the less ridiculous sounding one, is Stéphane Cornicard from off of Spectre and Saving Private Ryan.
There are a bunch of different possible endings, reached by the different paths you take through the story, leaving room for you to "lie and manipulate evidence", which sounds fun. Apparently it is but a few weeks away.
