In this episode we find the 4th motor age of the old episode, a very good scenario, which as always makes reference to history (Blackbeard ....), the same gameplay and an awful AI (sometimes too hard sometimes too easy). As against the atmosphere of piracy is excellent, the universe is large enough to explore is rich with numerous large and small islands or have must seek treasures ... etc Freedom is total both in the islands or on his ship, despite a huge map you can arretez you or you want to dive on it ... you can go "tuning" to improve completely (change sails color, change the bow, carry more ammunition ... etc) You will also find many activities (hunting, game lady ...), in short all for single player that has a very long life (20h 20h scenario related activities) + 1h for ps3 release solo mission with Aveline ., There the online mode which is pretty well done, old game modes are back on 8 new maps, game of cat and mouse ... So despite some faults that 4 th episode is very good.
