Those with Japanese PS3 systems found an unexpected surprise when booting up a US copy of Uncharted: Drake's Fortune. Most likely to meet Japanese ratings standards, the game will be censored when playing on a Japanese system. Most notably, there is a total absence of blood when shooting at enemies. Workarounds have been possible on other censored games, but so far none have worked for Uncharted.
Of course, the game wasn't too bloody to begin with. This is a strange, but ultimately not vital omission for those that have import systems.
