Orbital Defender Full for the iPhone and iPad
In the game, you control a small orbital satellite that spins around one of the various planets in our solar system starting with Mercury and advancing on. Each planet has multiple levels of play. As your satellite orbits, you shoot your various weapons at the attacking enemy ships, some more powerful than others.
This is where the games unique controls come into play. You can tap the enemy to shoot your basic weapon at them, being careful to not shoot at your own planet. As you gain additional weapons, you use other gestures like swiping to fire them.
The game has a very good help system that explains visually and with easy to read words on exactly how to play which is a nice change of pace.
The game does lack a few controls you would expect like being able to turn off the music and sound effects. It’s easy enough to just mute your phone, so this isn’t a huge issue. The game seems supports OpenFeint, the social game system for tracking high scores and achievements though it does appear to have an independent score keeping service.
The main issue with the game is there is a Game Center popup that pop’s up from time to time letting you know the game isn’t recognized by Game Center. The developer does not advertise Game Center compatibility, and this is probably an artifact of OpenFeint trying to integrate with Game Center.
The game is fun and challenging. Based on the first few levels of play, the later levels have to be really tough.
