Deaf and Hard of Hearing gamers will be happy to know that all dialogue is subtitled. Although it's not always evident which character is speaking (names aren't indicated), this doesn't really affect gameplay or the hokey story, and in-game hints have matching text—but can be hard to follow when the action is heavy.
