PlayStation CAMP's downloadable action adventure Rain is available starting tomorrow, for $14.99.
Today's launch trailer tells the story of an invisible boy and girl, who can only be seen when they stand in the rain. They are pursued through a rain-soaked gothic city by a monster. Their allies are cover and each other.
"Players must understand that at times what they are able to see isn't everything," according to publisher Sony's game-page. "They must use their imagination to interact with the environment and solve puzzles, and to help them along their journey to safety."
