where he is manufacturing copies of Light's robots. After defeating replicas of the Robot Masters, as well as several robots designed specifically by Wily to defeat him, Mega Man confronts Wily in a final showdown and defeats him before returning home to his family. The initial Western release of the game, while keeping the same basic plot, significantly changed some details from the original Japanese manual. In this version, Dr. Light and Dr. Wily (who is portrayed as Dr. Light's former assistant) co-create the humanoid robot Mega Man alongside the six Robot Masters, each of whom were designed for the benefit of Monsteropolis's citizens (no such place existed in the original plot). Dr. Wily, angered by Light taking credit for their work and desiring to use his creations for criminal purposes, steals the Robot Masters and reprograms them, then creates his own army of robots to seize control of Monsteropolis and declare it his own personal empire. Dr. Light, horrified by Wily's betrayal, sends Mega Man to destroy the Robot Masters and free Monsteropolis from Wily's machines. Gameplay Mega Man consists of six side-scrolling platformer levels freely chosen by the player. In each level, the player-character, Mega Man, fights through various enemies and obstacles before facing a "Robot Master" boss at the level's end. Upon defeating the boss, the player assimilates the Robot Master's signature attack, or "Special Weapon", into Mega Man's arsenal for the rest of the game. Unlike the standard Mega Buster (Rock Buster in Japan), the Robot Master powers have limited ammunition replenished by collecting ammunition cells dropped by defeated enemies at random. Enemies also drop energy cells that replenish Mega Man's health gauge. While the player is free to proceed through the game in any order, each Robot Master is especially vulnerable to a specific weapon, which encourages the player to complete certain stages before others. The player can also revisit cleared levels. Besides the weapons taken from the Robot Masters, the player is able to pick up a platform generator item known as the "Magnet Beam" in Elec Man's stage. Mega Man also features a scoring system where players score points for defeating enemies, and earn extra points for collecting power-ups from fallen enemies and for clearing each stage. Each Robot Master was worth a random number between 50,000 and 100,000 points whereas Dr. Wily was always worth 200,000 points. The scoring system was removed
