Update 2.1.2 introduces the American Grumman F5F Skyrocket heavy fighter, new experimental equipment, a unique supply crate, as well as an increased chance of reward drops for existing supply crates.
From November 16, the game will host the Crimson Dawn global event. Here you will see the return of the Bomber Escort, Invasion, and Attrition modes in which you try to achieve a common goal together with the other players. Reaching this goal will double the number of supply crates that you can receive. In these supply crates, you can find operation orders to obtain the brand-new heavy fighter as well as many other rewards.
