Killer7 (Japanese: キラー7 Hepburn: Kirāsebun?) is an action-adventure video game for the Nintendo GameCube and PlayStation 2. It was developed by Grasshopper Manufacture and published by Capcom. The game was written and directed by Goichi Suda, also known by the nickname Suda51, and produced by Hiroyuki Kobayashi. Killer7 features first-person shooter elements and a unique "on rails" control scheme, but the core adventure-style gameplay has been compared to Myst and Snatcher. The game follows an elite group of assassins called the "killer7". The assassins, physical manifestations of one man Harman Smith, perform hits on behalf of the United States government. Through these missions, the killer7 uncover a deeper conspiracy regarding the role of Japan in US politics and secrets about the nature of their organization. Killer7 was Suda51's first game released outside Japan. It received polarizing reviews due to its unconventional control scheme and complex noir plot. While some reviewers appreciated the stripped-down controls and stylized "arthouse" approach, others panned it as confusing and restricting. Jack Thompson, an outspoken video game activist, alleged that the game contains "full-blown sex sequences", but his claims were ultimately refuted. Despite these setbacks, Killer7's cult appeal led to remakes of Suda51's older works and the successful launch of No More Heroes.
