Shockman

A New Menace plays very differently from the previous title. Swordplay has been eliminated and is replaced by a ranged weapon much like Mega Man's Mega Buster. The world map, upgrades, and hostages have also been removed from the game. There are also now two side-scrolling shooter stages. Additionally, jump control has been altered.

A New Menace takes about two years after the original Cyber Citizen Shockman. Arnold is no longer a student and works as a cook in a local restaurant. Sonya remains a student. Since the fall of the Dark Skull, Doc has constantly suspected that another invasion was coming sending Arnold and Sonya on searches for the new invaders although never finding anything.

However, one day, after Doc is kidnapped, Arnold and Sonya find out that an alien empire led by Ryo is planning to take over the world. Also, two other villains have appeared with similar powers to Arnold and Sonya. They are dark Shockmen named Jeeta and Mue. Arnold and Sonya must now rescue Doc, stop Ryo from taking over the world, and avoid being killed by Jeeta and Mue.

Cyber Citizen Shockman 2: A New Menace received average reviews from critics. Japanese publication Micom BASIC Magazine ranked the game third in popularity in its July 1991 issue, and it received a score of 22.63 out of 30 in a 1993 readers' poll conducted by PC Engine Fan, ranking among PC Engine titles at the number 113 spot.
