StorylineEditA mysterious virus spreads throughout the Earth. Animals exposed to it are transformed into hostile, grotesque mutants and humans attacked by them fall into comas. Alex, the protagonist, is a biologist whose family has been infected. Suiting up and jumping into S.O.P.H.I.A., Alex seeks out to destroy the source of the virus beneath the planet's surface.
After the viral menace is destroyed, the Earth recovers and Alex's family revives. The game ends with a sequel hook, with a scene of a purple meteor heading towards the Earth, followed by the declaration that, "the battle has just begun."
Despite Overdrive being billed as a "re-imagining," much speculation can be made about the plot, especially in its relation to the rest of the series. Overdrive's Alex doesn't seem to be the same Alex Bufoni from Worlds of Power: Blaster Master, but there's no official word. If so, then it explains why he had the Sophia ready to go so soon, having perhaps borrowed it from Jason or Roddy. It is likely that Overdrive's Alex is simply a homage in name to the Worlds of Power book, much like how Eve was adopted into canon with Blaster Master: Blasting Again.
Alex may be the father of Jason and the grandfather of Roddy and Elfie. His young, unnamed son resembles Jason, and the fact that he possesses Sophia would explain why Jason eventually found the tank hidden near his home several years later. S.O.P.H.I.A. also appears to be the most primitive version of Sophia in the series, with no allusion to the version of the vehicle in its name, unlike Sophia 3rd and Sophia 4th. This could signify that S.O.P.H.I.A. is the earliest and original incarnation of the tank, and gives time for Alex to upgrade it to Sophia 3rd over the years before Jason finds it. If this is true, this would conflict with the previous continuity established when Blaster Master: Blasting Again adopted the Worlds of Power novel as canon. Sophia 3rd was a creation of Eve's home planet and belonged to her, and arrived on Earth when she did not too long before Jason discovers it. Overdrive makes no attempt to explain where S.O.P.H.I.A. came from, though the virtual manual claims that Alex built it.The identity of the purple meteor is impossible to discern from the game; it may be the arrival of a new antagonist, or it could be the Plutonium Boss on his way to burrow into the Earth, setting up the original Blaster Master and giving credence to the theory of Overdrive as a prequel and Alex being Jason's father.
S.O.P.H.I.A. and Alex have substantially less Life than in previous installments, but have the potential to have much more.
Here, Alex pilots the S.O.PH.I.A. through the various areas. If Alex steps outside of his tank, he'll take constant, minor damage until he enters Chambers or hops back inside the vehicle, which instantly restores his HP.
Alex can move and shoot in eight directions; he can also strafe.
Alex has four different weapons to choose from, each of which with their own power levels.
Overdrive contains many homages and subtle references to every previous game in the series. Among them are:
- A doppelganger boss from Blaster Master Boy
- A mutant bat boss from Blaster Master: Blasting Again
