OnLive’s been picking up a lot of steam this year, thanks in large part to a fairly substantial marketing campaign and promotions like giving out free consoles at the Penny Arcade Expo. That said, the service has just come to Android (and is coming to iOS soon, pending certification), meaning that mobile gamers will be able to play the latest big-name video games on the go.

The service has just launched a mobile app that will allow you to enjoy all the benefits of cloud gaming that the physical console does, except you don’t need the OnLive console and a TV to enjoy the games. The app is available for free, but will only be available in the U.S. and the U.K.

It’s being reported that “more than 25” of the OnLive titles will include touch-oriented controls. That means you won’t even need the OnLive controller to play these titles on the iPad. However, the majority of the OnLive library will be available to play with the controller (all you have to do is pair the controller up with the mobile device). The touch-friendly games include Assassin’s Creed: Revelations, Batman: Arkham City, and L.A. Noire.

I’m not going to lie: I haven’t spent much time with OnLive since I picked it up, mainly because I tend to use other consoles for my AAA games. I’ll certainly be willing to give it another go, since I’ll be traveling a fair amount over the holidays, will be lugging my iPad along with me, and love playing as Batman.

You can download the app on Android Market, and it sounds like the iOS version will be available shortly.
