Blaster Master Zero 2

The game plays similarly to the previous game. Players control the SOPHIA vehicle in the side-scrolling levels, exploring environments and defeating enemies using the tank's various weapons. The player character Jason can also hop out of the tank to enter various passages and doors, where the view switches to an overhead perspective. Players can find various upgrades to the tank that may allow access to previously inaccessible areas. Throughout the game the player also encounters various boss characters that must be defeated to progress to later levels.

The levels of Blaster Master Zero 2 are now separated into a world map. Each sector consists of a single planet with an interconnected overworld similar to that of the previous game, though smaller in scale. There are also several planetoids which are unlocked by collecting map items. Though optional, the planetoids contain small levels where Jason can obtain new upgrades for G-SOPHIA and himself.

The storyline continues several months after the events of Blaster Master Zero, in which a young inventor on Earth named Jason Frudnick encountered a frog-like creature which he named Fred. He was led underground by Fred to SOPHIA III, an armored tank known as a Metal Attacker. It was owned by the android girl Eve, who had traveled from the planet Sophia to destroy the evil Mutants, alien invaders that seek to consume planets and assimilate the native lifeforms. Together, Jason and Eve destroyed the Mutants and their Overlord, but the Overlord's core had infected Eve and SOPHIA III, forcing Jason to destroy the contaminated vehicle in order to save her.

In the months that follow, Jason creates GAIA-SOPHIA (G-SOPHIA), a new and improved version of SOPHIA III capable of space travel but the remaining Mutant cells in Eve's body have multiplied and are threatening to destroy her. Unable to find a cure on Earth, Jason, Eve, and Fred travel to Sophia to seek medical attention.

Developer Inti Creates was the team who created Blaster Master Zero, a reboot of the 1988 Sunsoft game Blaster Master. They went to work producing a sequel, using experienced staff from this game to finish development in nearly one year.

The game received "generally favorably reviews" on Nintendo Switch according to review aggregator website Metacritic. Fellow review aggregator OpenCritic assessed that the game received strong approval, being recommended by 92% of critics.

Mitch Vogel of Nintendo Life rated the game 9/10, calling it a "masterclass in retro game design". He stated that while "few could’ve predicted the surprise release of an original sequel", it exceeded its predecessor in every way, and praised the game's addition of a limited open-world. He also praised the addition of counterattacks to top-down shooting segments that increase the degree of skill-based play required and allow the difficulty to go much higher while still being fair.
