The grand-daddy of endless runners, Temple Run 2, is now available on BlackBerry by way of the Android build on Amazon. The gameplay is as smooth as anything you could expect in a native version, and the graphics are remain stellar. Follow these steps, and you'll be fleeing demon monkeys in no time.
Step 1: Install and log into the Amazon Appstore
Go to the Amazon Appstore download page in your BlackBerry browser (http://www.amazon.com/getappstore). Tap the "Download the Amazon Appstore" button. The Downloads window should pop up asking you where you want to save it and what the filename should be; just tap Save in the top-right, then tap the file when it's done downloading. If the download window isn't there, tap the overflow menu button in the bottom-right (three little dots), and tap Downloads.
After installation, open the Amazon Appstore, enter your Amazon e-mail and password, and tap the "Sign in with my Amazon account" button. If you don't have an Amazon account, tap the "Create account" button and follow the steps.
Step 2: Download and install Temple Run 2
Tap the magnifying glass in the top-right of the Amazon Appstore, and type Temple Run 2 into the search box. It should pop up in the results below; just tap the Free button to initiate the purchase. You'll have to tap another Install button after that, and confirm app permissions to complete installation.
Step 3: Open Temple Run 2
Tap the Temple Run 2 icon in your home screens to open it. Just swipe from right to left on your home screen until you find it, or tap the Open button in the top right of the installation window.
I've had good performance with no glitches to speak of, though your mileage may vary. Things take a little while to boot up, but once you're running, the game is extremely responsive to the frantic dodging you have to do to survive. Let's hear your top Temple Run 2 scores in the comments!
