Rough outline:

Killer 7, directed by Suda Goichi of Grasshopper Manufacture, is a "hard-boiled taste" action-adventure game. Mr. Suda's masterpieces include "Moonlight Syndrome" and "The Silver Incident", which also incorporate his unique outlook on the world and sense of vision. Along with scenario developments that draws the player into the game, these are traits of his works.

The player becomes Harman Smith who is the main character - an assassin who has 7 personalities residing within him. When he takes the form of his 7 personalities, he can use their weapons as well as their special abilities at will. He opposes Kun Lan - a man who possesses the "power of God" and plans to bring down the United States.

The lives of the man who plots to overwhelm the world with indiscriminate terror, and the man who attempts to put an end to this wave of violence, are intricately intertwined in a tragic tale of vengeance. Stylish cell-shaded graphics, dark and thrilling visuals with unique characters make up this fresh and stunning new game style.
