"Its been a roller-coaster ride beginning with one of the earliest MMOG launches to growing and supporting a fiercely-loyal player community all the while trying to continue the innovative and unique approach to development that's seen WWII Online stand alone as the ultimate PvP MMOG available", says Al "Rafter" Corey, executive producer for Playnet. "We're so proud to stand up and say that we're still here and thriving after 5 years. This promo is just a small way for us to say thank you to the thousands of players, past and present, who helped make it possible."

All players who take part in the celebrations from June 22 will be in the run to win prizes as well, including t-shirts and year-long subscriptions to the game.
