I just discovered this great game on the app store. I've been mildly addicted to Infinity Blade II for the past few months, so this makes a pleasant change. The game play is very similar to the Infinity Blade series, and is fiendishly difficult until you start leveling up!
Speaking of Batman - issue 2 of Batman Arkham City: End Game is now out on the DC Comics app for .99c. It looks great on the iPad, so treat yourself to some eye-candy! You can find some of my flats here.
