Developed by SCE Japan Studio, rain is a Sony PlayStation 3 exclusive Action-Adventure title released on the Play Station Network in the fall of 2013. A nameless boy, upon seeing the silhouette of a girl being chased by an unknown entity, wanders out into the rain of the city until he begins turning invisible like her. The boy discovers various other transparent creatures roaming around town, hostile to the girl and him. He must find a way to her among the endless rain, walking in a newly-discovered world only revealed by it.
The uniqueness of rain is the setting itself: the boy can only be seen while standing in pouring rain, as is the girl and the mysterious creatures. By walking towards shelter, players will only see the boy's footprints, so it's up to them to utilize the boy's visibility in the rain to navigate the city, solve puzzles and evade the creatures.
Compare Lost in Shadow, except it uses a Living Shadow in place of rain.
rain provides examples of the following:
- All Just a Dream: The boy and the girl eventually make it to the one house with light coming from it and find the girl asleep in bed. Combined with the fact that the boy was also sick in bed at the beginning of the story, this implies that he and the girl are having a shared fever dream.
- Animal Jingoism: The unknown bugs don't seem to get along well with anything; They'll swarm and leech the boy and the dog unknowns to death if they see either. They're the only unknown creatures that don't coexist peacefully with the other unknowns.
- Another Dimension: Chapters 7 and 8 take place in the dark, twisted world of The Unknown.
- Controllable Helplessness: Averted; despite the Unknown catching up to the boy at certain points in the game, the girl will invariably ensure he gets around by giving him an additional platform to reach higher positions and escape it.
- Determinator: The Unknown; even though it's trapped in a seemingly inescapable cage, it manages to get out and continue hunting the boy and girl.
- Escort Mission: Averted. The boy and the girl work as a team and mutually assist each other.
- Human Ladder: The boy and the girl regularly use this to reach things that are too high for them.
- No Name Given: The actual names of the boy and the girl are never specified.
- Super Drowning Skills: The unknown bugs don't seem to be capable of swimming or breathing underwater, vanishing completely as soon as they slip under the surface. It's common for puzzles involving them to end with the bugs being dropped or lured into the ocean.
- Weakened by the Light: The Unknown is vulnerable to light. At the end of the game, the boy and the girl kill it by dragging it into the sun.
