428: Fūsa Sareta Shibuya de

428: Fūsa Sareta Shibuya de (428 〜封鎖された渋谷で〜) is a visual novel set in the Shibuya ward of Tokyo where the narrative is presented using a combination of scrolling text, live action stills and video sequences. The game shares many story and gameplay elements with Chunsoft's 1998 sound novel game Machi, the most prominent being the locale, Shibuya. Although Chunsoft does not openly state 428 is a sequel, the game contains numerous references to Machi, and an early marketing slogan reads "Breaking a long silence, Shibuya gets going again."
