SilverPlay announces Louisiana, a detective-themed adventure game set around the turn of the twentieth century. The game will feature full 3D graphics and RPG-style dialog branching, though it does not have a set release date at this point. Here's a thumbnail:

The lazy summer sun is slowly penetrating the gloom of the local marshes, and yet the city is being overcast by a heavy creeping cloud of doubt and anxiety. There have always been a lot of murders in this neighborhood. Now, however, the situation is different. These killings are somewhat strange, lacking any apparent motive and too complicated to have been committed by a raging insane maniac. Before long, they catch the attention of the government authorities.
