What? You don't have a Sphero? Well, you're going to need one to play this amusing free game. Sphero is a neat little ball-shaped robot that rolls around in response to things going on inside your phone. In this case it rolls around your floor killing augmented reality zombies with fireballs. That's got pretty much all the makings of something awesome.

So you point your device's camera at the Sphero, and the undead will attack. As you guide your sphere of death around in real life, the virtual zombies respond to it. You can play the game anyplace there is a flat enough surface for the Sphero to roll around on.

There are a number of other Sphero apps, but the device itself is $99 (down from $130). Kidding aside, this one does actually look kind of compelling.

    Laugh it up, but when Sphero 2.0 releases with built-in flamethrowers, you'll be happy to have it in the zombie apocolypse.

      Suggest it. I need a few fiery balls.

      • Mr E

        I know a girl you can get those from....

    On a more serious note though, why is the sphero thing even necessary here? Based on the video, you don't interact with the real-life ball at all. It just rolls around, harassing your pets and housemates while you play the actual game.

      Because they need to sell more balls and make balls more lucrative. Wait, what were we talking about?

      Augmented reality with Sphero is simple and seamless for two reasons – Sphero is a robot, and Sphero is round. This allows us to employ a robotic fiducial, which provides never-before-seen freedom in characterizing the visual environment (since by definition a robot is a reprogrammable machine). With no auxiliary fiducial markers, Sphero can be effectively found and tracked at a distance, at any angle, and when partially obscured. A ball is the same from every angle, after all.

    Makes me glad I own a Sphero!

    Interesting Sphero article I read yesterday: http://www.forbes.com/sites/jordanshapiro/2013/06/03/a-fathers-day-gift-thats-narcissistic-but-not-self-indulgent. I am still not buying it, but I understand its appeal more and more as more apps/games come out that support it.

    Four times while using this app it simply returned me to the menu screen for no reason.

    It finds the sphero right away but once the zombies come out the lag begins to hit, The on screen target for your sphero starts to lag big time.

    I was never able to figure out how to kill a zombie and controlling the sphero well enough to actually run up to zombies was quite difficult since the sphero can not turn on a dime. It requires a wide arch to turn and start going the other direction, which makes game play less than enjoyable.

    Some features like detecting where the sphero is looked really cool at first glance but this app seems to need more refinement. I will just stick to driving my sphero around like a remote control car for now.

      David - What device are you using? We're working on a few fixes now.

      • David Becker

        I posted this to the review section on the app as well. I am using a Galaxy Nexus. I am running the latest sphero firmware as well.

    I really wish I had a practical excuse to buy one of these. I'd like to play with it and use it to entertain my cat, but I'm trying not to spend very much on the extra stuff right now.

    I have a funny feeling that I'll get a brilliant app idea that uses Sphero at about 1am tonight.
