Then, how did Phin Mason die?
After Miles uses his bio-electrokinetic powers to absorb the reactor's energy, Phin sacrifices herself by using her programmable matter boots to propel herself and Miles high up above Manhattan so Miles could safely release the reactor's energy stored inside his body, killing her in the process.
Also Know, what happened Phin's brother? But Phin is overcome with rage and resentment, still reeling from the death of her engineer brother, who lost his life trying to eradicate NuForm, which he invented but subsequently discovered made people sick.
Secondly, is Phin Mason really dead?
The blast, of course, will kill Phin, but she accepts her fate, taking responsibility for her actions, and begs Miles' to let go. But Phin dies, seemingly vaporized by the blast.
Is the tinkerer alive?
The Tinkerer, the game's main antagonist, turned out to be Miles Morales' own friend. One of his best friends, in fact. A common occurrence for superheroes, it seems. She is most likely dead, but this is a superhero medium.
