Aurora Feint is already hailing the launch of OpenFeint on Android a success, revealing that four of the first eight titles enabled on the network have hit the top 15 on Android Market.

The second wave of 12 OpenFeint releases, set to hit Google's platform this week, will no doubt be hoping they can foster the same level of success, with Supermono's MiniSquadron and Halfbrick's Fruit Ninja having hit the top two spots for paid games within the first 72 hours.

All guns blazing on Android

"The past two weeks have proved to us that Android users are hungry for great games - and they’re willing to pay for top quality content," said CEO Jason Citron.

"Over the next few months, we’ll continue to roll out games and help establish the paid gaming market on Android. We couldn’t be more excited about this latest Android release."

Though the bulk of its userbase is naturally signed up on iPhone, launching on Android has also helped push OpenFeint through the 40 million users barrier, making the network – in its own words – the largest of its kind on mobile in the world.

In all, Aurora Feint claims 160,000 new users are signing up to OpenFeint every day, across a total of 3,100 games.

The next step

The next 12 releases to make the leap to OpenFeint on Android includes Glu's Super K.O. Boxing 2, PikPok's Flick Kick Rugby, Touch Racing Nitro and Penalty World Challenge 2010 from Bravo Game Studios, ChickenBrick Studios' Cestos 2: Party Time, Speed X from Hyperbees, Playbrains' Babo Crash Deluxe, Kamikaze Race from TastuPlay.com, Brain Twister Lite and Color Cocktail Lite from The Game Boss, ustwo's Dot Dot and SkyForce from iDreams.

All such titles will be featured as a Spotlight app post launch, giving them visibility on the marketplace and handing users a chance to enter specialised competitions.

Developers on either Android and iPhone interested in incorporating OpenFeint into their platform can sign up for the free SDK on the firm's website.
