The app Achilles Defense by PTT-Solution is still live on many european appstores, in fact they updated the game and added more stolen content. They only removed the app from the us store.
You can check how it is still live on other stores :
Germany, France, Japan, Indonesia, Mexico, Netherlands, Norway, Taiwan, Belgium, Bulgaria, China, Denmark, Estonia, Poland, Portugal, Russia, Romania, Sweden, Singapore, Thailand, Turkey.
We have contacted apple again and will seek legal aid because it seems the only way to deal with this.
EDIT June 1st, 2011:
Gladly the app has been removed from the above stores.
