Time Diver: Eon Man

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![2]

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.

There are three known versions of this game. The first two are identical except that the title screen is slightly different. The third was silently released into the Asian game market as Time Diver: Avenger, which was developed and published by Nitra, short name of Nitra Semiconductor Company (九統半導體股份有限公司).[3] The only differences were the title screen, instances of "Eon Man" altered to "Avenger", the copyright listed as 1994 and the Taito logo changed to Nitra.[4] It is unknown if Nitra was another company that bought the rights, a subdivision of Taito developers, or simply a group of hackers (without a Nintendo and Taito license) who got a hold of a prototype copy of the game.
