Last year Perfect Cell was released at a fair price of $5.99 considering the content and originality of the game. The premise of Perfect Cell is that you are a man made creation that needs to escape from a facility and destroy soldiers in the way while avoiding traps. The game is now priced at only 1 dollar for either the Ipad or Iphone. The game is very fluent and well worth a dollar at this point. I doubt the sale will last long so grab it while you still have the chance.
