War Thunder - B17 squadron
Gaijin Entertainment has announced that its War Thunder World War II-based online flight sim has officially entered open beta. The title, formerly known as World of Planes, has been in development for over four years. The open beta comes almost a year to the day after Gaijin's announcement that the game had evolved "beyond pure aerial combat."

Gaijin previously developed Birds of Prey, a console-based entry in the long-running Sturmovik series.

The company has released an open beta teaser trailer that you can view after the cut. You can also join the beta test via the game's official website.
