Pirates of the Caribbean: Armada Of The Damned? Looks more like Fable On The High Seas to me.
That may sound mean, but I like Fable, and if this is Fable with tall ships and zombie pirates, then that's fine by me.
The game is an action RPG, with the emphasis on action, and while it's set in the PotC universe, it's got practically nothing to do with the events of the recent film trilogy.
It's due this Fall for the 360, PS3 and PC.
