War Thunder

The game is set to contain aircraft, armored vehicles, and ships from the pre-World War II era to the early Korean War era. Some maps in the Historical Game mode are similar to real life WW2 conflicts. i.e Pearl Harbor.
The average size of maps in the game, currently range from approx, 100km x 100km to 200km x 200km. Although the engine powering the game is likely to archive larger map sizes in the future.
