Although its name should be "Regia Marina" due to the introduction of the Italian Fleet tech tree — only for those who buy preorder early access packs at this stage or complete various missions, as usual — War Thunder 1.99 comes as "Starfighters" thanks to the F-104 jets that have been added to the game as well. Obviously, there is much more to it than just the above.
