Stellar Wars is like a swiss-knife of mobile gaming. The types of gameplay one will face include space shooting, planetary defense, arcade action, endless running, and more. What's even better is that you will also fly a spaceship (always an excitement), build robots and control them directly, battle the huge bosses sci-fi games can never do without, and indulge in hours of gameplay.
Unless you hate sci-fi, don't miss on Stellar Wars, as free games hardly get better than this. The game requires iOS 5.0 or above, and is compatible with iPhone 4 and later, iPad 2 and later, and iPod Touch 5th generation. Head to the link below if you want to get it.
