This is file is named PVP cove and the little part that can be seen seems to have to oppsite forts. This island is possibly an island in which the Spanish and French fight for and we're forced to join sides once we dock on the island. This would be just like SvS in the sense that you're on a team.
This would be a much better idea than a free-for-all PVP island, in which guilds and grouped pirates could attack incoming pirates before they get a chance. The Spanish Vs. French would also force people to act like teams.
All I have is a picture and all I know is that the name is PVP_Cove. No ideas on what the future holds for this model, though.
