In Memoriam uses alternate reality-style gameplay, in which the player receives e-mails from other in-game characters. The player needs to find information and clues to the games' puzzles on the Internet, both from real websites, and from specially-created websites that have been mixed in with other "real-world" domains. The plot centers around the disappearance of journalist Jack, and his young female companion, Karen, in Europe while investigating a series of bizarre murders. (wikipedia.org)
