iPhone social gaming service Scoreloop is now supporting the Unity development platform, allowing developers to mix fancy 3D visuals with cutting-edge connected features in their games.

"Unity is the premier gaming engine for the iPhone and Scoreloop offers the most sophisticated mobile social gaming platform for the iPhone. We simply had to combine the two," says Scoreloop CEO Marc Gumpinger, Scoreloop CEO.

"Unity developers now get seamlessly integrated support for online high scores, player-to-player challenges and Push Notifications for even more thrilling games."

We've said this before, but competition in the social platform space for iPhone games is intense. Aurora Feint, AGON Online, Gamespy and publisher-developed platforms like ngmoco's Plus+ and Chillingo's Crystal are competing to sign up developers.

By hooking up with Unity, Scoreloop is clearly trying to get a step ahead of the competition. However, the announcement doesn't mention the word 'exclusive' anywhere, hinting that the company's rivals may also look to support Unity.
