Mega Man IV is an action-platform video game by Capcom for the Nintendo Game Boy. It is the fourth installment in the handheld version of the Mega Man series. The game continues the quest of the protagonist Mega Man in the struggle with his long-time nemesis Dr. Wily, who sends out a disruptive radio signal to cause a rampage, citywide destruction from dormant robots. 

Mega Man IV features the traditional action platforming gameplay of the prior games while introducing one new feature, the ability to purchase items with power-ups found throughout each stage. As with previous Game Boy releases, the game incorporates gameplay elements and bosses from two sequential Nintendo Entertainment System (NES) games: Mega Man 4 and Mega Man 5. The plot of the game once again involves the protagonist Mega Man trying to thwart the world domination plans of the infamous Dr. Wily.

On a seemingly peaceful day in a large city, Wily appears in the sky in his flying saucer and sends out a radio transmission that causes all the robots at the annual Robot Master Exposition to go on a rampage. He then sends eight new rebuilt robots of his own to different parts of the city to lead the destruction. Having resisted this reprogramming signal, Mega Man responds by defeating all four of these previous foes in battle and chases Wily to a large tank.

Inside the tank, the hero encounters Ballade, yet another robot specially designed to kill him. Mega Man defeats this new enemy, pursues the remaining enemies in the city, and returns to the tank. At its core, the gameplay is still the same as the previous 3 Mega Man Game Boy games. The player takes on the role of Mega Man as he traverses a series of two sets of selectable action/platforming stages in any order desired. The player’s initial weapon, the “Mega Buster”, can fire both small shots and much larger and more powerful, charged blasts.

Each stage is populated with various types of enemy robots and a single Robot Master exclusive boss. Beating the Robot Master will earn the player its special “Master Weapon” for use throughout the rest of the game. Clearing 2 of the Robot stages also gives the player access to abilities from Mega Man’s dog Rush, who can transform into a springboard for reaching high platforms or a jet for crossing large distances. Also, the game’s first four Robot stages each house a letter (“B-E-A-T”) that spell out the name of the bird Beat.

Collecting all 4 letters endows the player the ability to summon upon Beat to assist by attacking enemies. On the other hand, the game’s latter four Robot stages each house letters that spell (“W-I-L-Y”) which would be imperative to collect in entering to the first part of Dr. Wily’s fortress. The stages also contain hidden passages where the character Proto Man leaves the player items, often giving “Super Tanks” that refill all weapons energy and health energy.
