Featuring a robotic protagonist that could siphon the abilities of his adversaries, Mega-Man ロックマン2 Dr.ワイリーの謎 Rokkuman is a side-scrolling platformer that begins the never-ending struggle between cheeky hero Mega rock-man and the evil roboticist Dr. Wily humanoid robot Mega-Man ロックマン2 Dr.ワイリーの謎 Rokkuman created, by genius Dr. Light, alongside seven other robots (each designed for a specific industrial task, with the exception of housekeeping robot Roll). When Dr. Light's assistant, Dr. Wily, takes control of the robots (with the exception of rock-Man and Roll) with plans to take over the world, it's up to robots to venture through Monsteropolis, dispose of the rogue robots, and stop the plans of the evil roboticist.
