Remember Ingress, the Google-developed project that entices you to get outside with the promise of some light gaming? On top of iOS and Android, it now works on Android Wear, meaning you can join in the fun with your smartwatch rather than your smartphone (though you'll still need that too, of course). To get you up to speed, you play either on the "enlightened" (establishment) side, or as a rebel on team "resistance." The idea is to attack, defend or reinforce "portals," which are local landmarks like village squares or statues. The game notifies you when friendly or enemy portals are in range, and whether or not they're under attack.
