The Android market is slowly gaining steam. One of the original iOS hits is now making its way to Android devices. If you don’t have iOS, now is a good time to jump in. The game can be had on the Amazon App Store for free for the first 24 hours. After that, it will be sold for $2.99.

From the press release:

    SUBATOMIC STUDIOS has officially launched Fieldrunners HD, making the hugely popular Tower Defense game available today for Android users worldwide. Fieldrunners HD can be downloaded for free for the first 24 hours in the Amazon Appstore, while non-US Android owners can grab the game for $1 for the first day in the Android Market. After the first 24 hours, the game will continue to be sold in both stores for $2.99. The game will be available to US based Android users in the Android Market two weeks after its initial launch.

    “Amazon and Google have been very helpful,” said Jamie Gotch, CEO of Subatomic Studios. “Releasing in the Amazon Appstore in the US while simultaneously launching in the Android Market for international customers is something we are very excited about. Hitting both marketplaces in the same day allows us to reach our whole, international fan base and we wouldn’t have been able to do it without the support of both Amazon and Google.”

    Subatomic Studios had originally planned to release Fieldrunners HD for free in the Android Market, however their agreement prohibits developers from launching a game for free then transitioning it to paid. After hearing about the situation, Amazon approached the studio with a two week exclusivity agreement in exchange for allowing Fieldrunners HD to launch for free in the Amazon Appstore. Upon this news International fans voiced their concerns, since the Amazon Appstore is not available outside the US. Amazon listened, eliminating their international exclusivity agreement so that Fieldrunners HD could launch on the same day in the Android Market for fans outside the US.

    “Once again, Amazon has shown that they care about our fans and our studio,” said Alec Shobin, Marketing and PR Manager of Subatomic Studios. “After announcing our exclusivity with Amazon, our fans outside of the US became very vocal about how this arrangement delayed the international release of Fieldrunners HD. Amazon took note of this and allowed us to break international exclusivity, and that flexibility is allowing us to launch in a way that will really please our whole fan community.”

    Fieldrunners HD, the most anticipated and visually stunning game in mobile Tower Defense history, is coming to Android with updated hi-definition graphics. You will be able to defend your base and control the field using a diverse selection of upgradeable towers in an epic adventure and master a wide array of tactics and strategies to help you stand victorious against countless waves of unique land and air combatants. Do you have what it takes to defeat the fieldrunners and rise to the top as the ultimate Tower Defense champion?

    One of the first runaway successes on the iPhone, Fieldrunners has won an assortment of awards, ranging from the prestigious “Best Mobile Game” and “Achievement in Art” awards at the 2009 Independent Games Festival, to being featured on the cover of TIME Magazine as one of their Top 10 Games of 2008, where it was listed amongst such titles as Grand Theft Auto IV, Little Big Planet, Gears of War 2, Rockband 2 and Spore.
