Come play MapAttack, a real-time urban geofencing game for iPhone and Android! Bring your device (iPhones running iOS 7 and new-ish Android devices). Teams will start at Backspace and collect points around the city blocks of Portland. Teams that get the most points win! Built on the Esri Geotrigger Service.

After much work, the game is working very well and is very fun to play. We'll have PacMan ponchos if it's raining out, but you should bring running shoes or warm clothes if you feel you need them. Come with phones pre-charged!

Meet at Backspace around 12:30pm! Game will start shortly after! We'll have multiple games, so don't worry if you can't make it at the exact time.

What to expect: Games will last from 20-30 minutes and can be played on bike, by foot, or even by public transit.

Forecast for Portland this Sunday! Partly Cloudy with a high of 66 and a low of 43 °F.
