Use multitouch to spin and zoom entire worlds in Star Defense, the highly-anticipated strategy title created exclusively for the iPhone and iPod touch. Maximize your recon and plan carefully - each planet has unique pathways to protect, weapons to deploy, and enemies to overcome.

Survival depends on your ability to respond to the S'rath invaders in real time and build a mixture of towers that counteract all known alien units and resistances.

Once you've mastered taking on the S'rath, put your skills to the test in Challenge Mode and compete against your friends over Twitter, Facebook, or email.
