[Free-$1] Score another victory for Android gamers: Fieldrunners HD launches today on Android-based devices! In typical Android fashion, it’s like nine years behind the iPhone launch. But that’s ok! Better late than never. The popular tower defense game will be available starting at 12 AM Pacific Time on the Amazon Appstore for free for the first 24 hours! It will also be available on the Android Appstore for a discounted price of $1 for 24 hours. After that, price jumps up to a mortgage-inducing $3. Screenshots of some gnarly tower defending action below, but you probably already know how the game looks because all your buddies with iPhones have been cramming it down your throat since 1997. No matter, we’re still pumped to play it on Android!
