A number of Gameloft iOS games have dropped to $0.99, which is extremely good value for some of their titles. As far as I can tell the sale is for iPhone and iPad, so if there is a separate 'HD' version of the app it too is discounted to $0.99

Too many 0.99 games at the moment but too little time.
BTW, Jelly Defense also 0.99 on iphone and ipad. Great game I have it on Android free.
For myself I prefer this kind of games on iPad instead of FPS.
FPS I would prefer back to my PC.
