The game was sponsored by Electronic Arts but is more of a tech demo than a commercial game. You can read about it here: http://bits.blogs.nytimes.com/2012/06/27/e-a-and-google-got-game/. And you can see a video of the game in action at the blog of the guy who led the team here: http://noahbench.blogspot.com/2012/06/strike-fortress.htm.
At the moment, the game only runs in Chrome and only on Android 4.0 (Ice Cream Sandwich) and (I assume) on the new Google Nexus 7 tablet that was unveiled today (I'm a hardware person as well as software and I salivate at the idea of a 4-core Tegra tablet made by Asus ... and only $200).
Anyway, this can do a lot to convince people to look at HTML5 and help Construct 2 grow.
