[4] Jason's new vehicle, the G-SOPHIA, is functionally identical to its predecessor SOPHIA III, but has a new GAIA-System feature that allows it to recharge its subweapon energy from concussive impacts, like that of long falls or enemy attacks.

[3] Jason is also given a new Blast Counter technique when in the overhead areas, which lets him immediately shoot or dash into enemies when crosshairs appear on them before they attack.

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.

As they approach the last sector, Jason and Eve discover an enormous planet-sized Mutant who guards the dimensional tunnel to Sophia within its surface.

The emblems are activated and summons the other Metal Attackers from earlier in the journey, who assist Eve by distracting Drolrevo as she charges up ANDREIA's Acceleration Blast and fires it at the Mutant's cocoon.

The blast destroys the cocoon, inadvertently heals Eve of her infection, and frees Jason and G-SOPHIA, allowing him to finish off Drolrevo as his true form emerges.

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.

Calling the game a "ton of fun", he goes on to state that the "very nature of what makes Blaster Master gameplay so excellent has never shone so bright and wonderful".

Stating that most aspects, such as the graphics, story and soundtrack, were superior, he called the game "well worth exploring for fans of Inti Creates and Blaster Master".
