Pirate101, and the development team is in a celebratory mood. it's understandable considering how many games don't make it to a year or even out of beta. So from now until October 31st it's time to revel in all the birthday celebrations you want, starting with an entire game decked out in birthday regalia. Which will look a little odd next to the usual pumpkins, but whatever.
The game is also offering two bits of accoutrement for players, veterans and novices alike. All players are eligible to receive a free birthday hat, and the game will also sell a birthday cake eyepatch in the cash shop for a limited time. (The eyepatch looks exactly like you would expect something with that name to look, if it was unclear.) So kick back and enjoy some piratical birthday bliss with a new hat.
