Murder on the Mississippi, fully titled as Murder on the Mississippi: The Adventures of Sir Charles Foxworth, is a 1986 detective adventure game developed and published by Activision for the Commodore 64, Commodore 128 and the Apple II computers, and licensed by Jaleco exclusively in Japan for the Famicom and MSX2 as Mississippi Satsujin Jiken (ミシシッピー殺人事件, lit.

It is an adventure game in which the player must solve a murder mystery on the luxury ship "Delta Princess".

[1][2] While heading to New Orleans from St. Louis on the ship "Delta Princess", detective Sir Charles and Watson are caught up in the midst of a murder case by chance, that they must solve.

There is also a trap in Room 16, in which a knife flies through the air towards Sir Charles immediately after he enters.

Unless the knife is dodged it hits Sir Charles in the head and kills him, resulting in another instant game over.

While solving the case reveals the true criminal, the identity of the person that set these traps remains a mystery.

Each suspect can only be spoken to once per piece of new information – consequently, if there is a piece of information missed the first time around, since it is impossible to talk to them again this can lead to the player becoming impossibly stuck in the game and unable to progress any further.

Reasons cited include that the lack of a save feature, necessitating that the game be replayed from the beginning every session; the instant-death traps being unreasonable; the specific order of steps being required to complete the game being unreasonably particular; re-interviewing characters being impossible despite the information they offer changing based on ostensibly illogical requirements; and adult themes and language being used despite the Famicom's young audience.
