What it does not have? The Assault mode that presumably gave it its name.
“Available in two iterations, the new game mode challenges players to defend a strategic location against waves of enemy ground vehicles or aircraft. For tankers, combat is fought tank to tank on the ground, with the ability to temporarily support teammates in attack aircraft or bombers. Pilots are tasked with maintaining air superiority over a zone by fending off enemy bombers approaching from all directions. As each successive wave is stronger than the previous one, players have to work together to hold out until the end, upon which they will receive well-deserved rewards.”
That mode is on the way “soon after the update 1.67 launch.” In the meantime, check out the trailer!
