Capture the Flag—a game in which two teams try to steal a flag from the other team’s base—typically requires stealth, speed, and people under the age of 12. But Newmindspace, the folks behind such bizarre urban sports as the Lightsaber Battle and Pillow Fight NYC, have teamed up with the fun-loving people of Urban Madness to bring the children’s sport to us slightly older kids. To play, you’ll need a cell phone and a flashlight if you want to see where you’re going. When they did this in Toronto, hundreds of people showed up—expect total madness.
