The developers of Kentucky Route Zero recently released a free interactive play that takes place in the KRZ world, written by one of the game's characters. It's a great creepy play, and a good way to get a feel for the mood of the full game.
If you don't know it, Kentucky Route Zero is a point-and-click adventure game about a delivery driver trying to find a mysterious road and deliver some antiques. The Entertainment gives a peek at the characters who live in that strange world. It's a great way of fleshing out the game world for players, but it's even better as a teaser for those who haven't tried it.
