Uncharted once resembled Bioshock according to dev
According to a developer at Naughty Dog, the original Uncharted bore a surprising resemblance to Bioshock at one point early in development.
The co-president of Naughty Dog, Evan Wells, said that early in the development process Uncharted: Drake's Fortune took place inside an underwater facility which he compared to Bioshock.
It was apparently still in this state when it was pitched and accepted by Sony.
He joked about the irony of the fact that Bioshock once took place on a tropical island early in its own development.
