Yes, the fourth numbered game in the series involves pirates. And some coral reef swimming, by the looks of it.
I've never played these games, but knowing that the last one disappointed quite a few people, the cynic in me sees them tacking the premise on to what would appear to be a proven concept (except without Johnny Depp, it really isn't) to win crossover fans.
Am I wrong, fans? Does the prospect of assassinating pirates and/or sailors kick things up a notch?
Kotaku has a long list of reasons it could be pretty good.
