Curse: The Eye of Iris is a survival horror game that pretty much fits the style set by others in the genre. You are trapped in some large building (The Museum of Great Britain) with monsters coming after you and a limited amount of weaponry as you work through puzzles and try to figure out some sort of mystery.
In The Eye of Iris, you play as two characters, Darien and Victoria. Darien received a letter from his friend (Victoria), who works at the museum, to meet her and get a preview of the new Iris exhibit. Mind you, this is an exhibit that Darien's dad helped to uncover before his mysterious death. Unfortunately, before Darien can get to the museum, a thief breaks in and accidentally releases a curse upon the place.
Early in the game, Darien finds out that this curse is somehow linked to his father and his family. Now you and Victoria must explore the museum in search of a way to break the curse and put the evil back in its place.
Along the way you can collect various items; these pick-ups include documents (letters or notes from people that help explain exactly what is happening), weapons and ammo and other items for use in puzzles or health. Like in most survival horrors, you can combine various items if you don't have exactly what you are looking for.
The story is an interesting twist to the genre-typical style, but it still fits the pattern all too well. Because of this, Iris tends to be more like a 'me too' game then anything truly innovative.
