Marvel: Immortal Sacrifice

Reborn and ready to make the most of his second chance, William feels like there is something familiar about his surroundings.

His little brother James Howlett.

There's a kid named Victor Creed too.

And what is this power that lets me sacrifice body parts to gain abilities related to them?

Sacrifice a lung, get sonic abilities?

What else?
