Naomi Hunter did not die in Metal Gear Solid 4.
Nano machines can like heal Vamp after being shot a million times but can’t cure cancer???
Bullshit she’s alive and was lying about cancer cause she knew Snake and Otacon would believe her.
I always thought she faked her death so no groups would continue trying to use her for their own ends, and that most people didn’t consider that likelihood because they didn’t want to really put much thought into Naomi as a character.
