That's also not the Kindle Fire. It's the iPad 2 running Assassin's Creed: Recollection, whose liberal use of screen real-estate makes a great case for gaming on a 10-inch tablet as opposed to a 7-inch one.
That's not the Kindle Fire. It's the Samsung Galaxy Tab 8.9 running Shadowgun, which we easily downloaded from the Android Market. Not so easily done on the Kindle Fire. In fact, unless you have access to the game's APK or are interested participating in some illegal activities, it's damn near impossible to get.
