World of Warplanes is the upcoming airborne shooter from Wargaming, the maker of World of Tanks. Following a long Closed Beta stage that has seen over 2.7 million registrations from all around the world, Wargaming is adding new features to the game before the launch of the Open Beta. Closed Beta testers will receive rewards for the OBT and the new Unified Premium Account feature will be introduced at a later stage. UPA gives players the chance to purchase one premium account that works for all Wargaming titles.
