Time Diver: Eon Man Nintendo

Time Diver: Eon Man is a Nintendo Entertainment System video game developed by Atlus for Taito. Despite being completed in 1993, it was never commercially released. The game is completely finished, receiving a four-page strategy guide and review in issue 45 (February 1993) of Nintendo Power. Despite this, the game eventually disappeared from the Pak Watch section and was subsequently unproduced. Time Diver: Eon Man started life as a sequel to Wrath of the Black Manta, according to an interview the Game Developer Research Institute conducted with the game's planner.

Earth, 60 years into the future. The world is virtually crime free thanks to the Clear System invented by Kane Nelson, scientist extraordinaire. That is, until a secret organization called Romedrux decides to challenge the system by unleashing a plague of crime. In order for them to succeed, they'll need to prevent the Clear System from ever being invented, and that means eliminating Kane or his ancestors. Los Angeles, 1993. Dan Nelson thought he was an ordinary student living in LA until the day he found himself under attack by Romedrux warriors. During the attack, Dan learns about his future son, Kane, and vows to protect his family past, present, and future. It's a race through time in this new sci-fi thriller from Taito!

Time Diver: Eon Man had five levels set at various points in time. These include: the opening Peaceful (1993), Wild West (1882), Devastated (2052), Devastated (1993), and a Peaceful Utopia version of 2052. For the time, an unusual feature was a randomized stages order, with the exception of Level 1; allowing for some variation when playing through the game multiple times.
