428 is a visual novel adventure game where players take part in events from the perspectives of multiple protagonists, all acting in parallel with no knowledge of each other. Set in the modern Japanese city of Shibuya, Tokyo, the characters are involved in a mystery that cannot be solved without their interactions, and the plot is advanced by following clues found within the game's text and accompanying video sequences and making decisions on which path each protagonist should follow. Depending on the player's choices, a number of new scenarios become available, which ultimately lead to different outcomes and endings. The game has up to 85 different possible endings.
