Earth Force AR

Your mummy always said there were no monsters. No real ones. But there are!
Earth has been invaded by alien lifeforms. Diplomacy has failed. They have refused to co-exist with us. They just want us to die!
Only you can save Earth in this high octane Augmented Reality experience, that brings the classic arcade games into the modern age.
Travel around the world saving cities from devastation. Fight aliens as they evolve into new stronger lifeforms and destroy the end-of-level bad guy to progress to the next chapter in this saga.
Keep your distance! Don't let them touch the cities - these things bleed acid and contact results in immediate death. And then... it’s Game Over, man. Game Over!
You can use harsh language, but you can also deploy multiple super weapons to defeat the different formations. All super weapons can be obtained for free in-game, no need to spend endless money buying supplies.
Share your high scores with the world and become the greatest fighter in the Earth Force Academy.
This AR game pushes the iPhone to the limit using hundreds of thousands of polygons per second.
This is a very very hard game to complete, I can't lie to you about your chances, but... you have my sympathies!
Great new features from all the excellent feedback I have received.
Top tip!
