Frankly I think whether or not V survives is largely a headcanon thing. Maybe you head off into the sunset with the Caldos and find help. Maybe you knock over the space casino and buy yourself something like the Relic with all of your stupid new wealth. Maybe you turn into an AI and become a ghost in the machine.

Or maybe you develop natural charisma and an impressive cock, who knows.

Point is they left it vague and uncertain on purpose in several of the good (ish) endings. I get why, but it always felt kinda cheap to me. But it IS a noir story and those aren’t known for fairy tale endings.
