There should be three upgrades for astrum. One that makes the turrets be able to move 360, one that makes it have longer range on Ai cannons and use the plasma rounds with the ai cannons at any range and last upgrade should add a anti missile system kind of like abram x but can shoot down missiles faster and up to three at a time so you don't get spammed by missiles every half a second. I think the astrum should be like the ultimate air fortress
@@LEIFISONFIRE That is right, it is an air to ground offense type, but even with that the offense is weak Anyway, the Nova Blitz video is here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CXrhPZ4sqM0.html
