Mega Man 10 is a
side-scrolling platform game following the
gameplay formula established by prior
Mega Man games. The player is initially tasked with completing an octet of levels, which can be completed in any order. Each of these
2D side-scrolling stages contains obstacles and traps to overcome and enemies to shoot. Various power-ups such as health and weapon ammunition can also be found or picked up from defeated enemies. The end of the stage presents a
boss battle with a Robot Master. Victory over the boss will earn the player its special weapon, which can be used throughout the remainder of the game. An in-game shop allows the player to use
screws picked up in the stages to buy
extra lives, energy tanks for refilling health and weapon power, and other useful items. Like Mega Man and Proto Man, the third protagonist, Bass, has unique abilities. He has a rapid-fire arm cannon that can fire in several directions, but each shot does half the damage of one of Mega Man's shots, his shots cannot pass through walls, and he cannot move while shooting. He also has a dash maneuver for longer jumps and the ability to summon his wolf Treble to allow him to fly, provide him with power-ups, and save him from bottomless pits. The three Special Stages are based on levels in the
Game Boy Mega Man entries and have bosses named "
Mega Man Killers" from three of those games: Enker from ''
Mega Man: Dr. Wily's Revenge, Punk from Mega Man III, and Ballade from Mega Man IV''. Out of the three playable characters, only Mega Man is able to acquire their special weapons and use them in the main game. When the game was later integrated as part of
Mega Man Legacy Collection 2, all of the former downloadable content from the original release was included in the game. These newly incorporated sections are unlocked either by completing the game once or by entering the secret code at the
Mega Man 10 title screen. ==Plot==
