In addition, their shots can still be reflected by shields. The massive damage increase makes their potential DPS output on par with Nyon Exists (flash only in the mobile version their damage is nerfed) however, they lack any special abilities for utility beyond simple damage. If the player manages to keep some Nova Turrets long enough for them to reach rank VII, they can be (fairly) cheaply evolved into Galaxy Turrets. Note that Nova Turret shots can be reflected by shields. Of course, as the player unlocks better units, Nova Turrets will quickly become obsolete. It is better than the Core Blaster (the only other offensive unit available from the beginning) at dealing damage due to its faster fire rate and better damage. New players will rely on Nova Turrets to kill enemies, as it is one of the only offensive options available to them at such an early stage in the game. Galaxy Turrets deal much more damage than Nova Turrets. Upon reaching rank VII, you will have the option to pay 50,000 (500 in the mobile version) to upgrade the Nova Turret to a Galaxy Turret. (rank VII, includes buffs from self-upgrades)
