As announced by Sony Online Entertainment, its Pirates Buddy Key program is active as of yesterday. This marketing move is nothing new, but it has proven itself as a good way of getting new users.
Everybody with a Pirates account will get three buddy keys for the game. This will allow their buddies to test the game free of charge for a period of 14 days. The keys can be used immediately, or you can save them for a rainy day, as the 14-day period starts right after the key activation.
You can get the keys on the PotBS site, here.
