It's great then that a sequel is almost ready to be launched with Sky Force Reloaded hitting Android, iOS and Apple TV soon.
Curiously enough, there was a Sky Force Reloaded back in the Java era of mobile. And was even ported to the iPhone. I'm sure the title is a reference to Sky Force's lineage and, as such, becomes a testament to how far mobile has come.
Sky Force Reloaded will still be free to play and will feature a new card system that should shake up the structure of the game.
