Back in early March we told you about Zynga’s upcoming Temple Run-style game called Running With Friends, which was just entering a beta period in the Canadian App Store. Early today, Running With Friends (Free) bid adieu to its limited beta launch and is now available in the US App Store and internationally. VentureBeat has uploaded an official trailer, check it out.

So, endless runners, ya’ll. By now you know what they are, you’ve likely played many different kinds, and here’s a new one from Zynga. I’m not really sure what else there is to say on the matter. Running With Friends is free for iPhone or iPad, so you can just download it and try it yourself if you’re dying for a new endless runner, or check out the forums for discussion.
