Based on Defender, one of the best retro arcade games of all time, Planet Defence is now available for the iPhone and Touch.
Planet Defence is a fast-paced horizontal shoot'em-up featuring Tilt or Touch control to maneuver your space ship.
Defend the planet by protecting the humans that roam on the planet surface.
Green aliens skim the planet surface and pick up humans, when they reach the top of the screen they mutate and the human they carry is lost.
When there are no more humans left the planet explodes. New humans are dropped off every fifth level and the planet is restored.
How many levels can you survive?
