Game Description: In Mega Man 4, players once again control the Blue Bomber as he battles Dr. Cossack, a new villain (though later revealed to be manipulated by Dr. Wily). The game introduces the Mega Buster, allowing Mega Man to charge his shots for more powerful attacks. Players defeat eight Robot Masters to gain their unique weapons before facing off against Cossack’s fortress. The game builds on the strong platforming and shooting mechanics of its predecessors with refined controls and level design.
