Above and Below Hamburg
GPS Mission on TV
(Tunnel below river Elbe, Hamburg; picture via wikipedia)
GPS-Mission even works in the tunnel below the river Elbe - as has been shown by the German TV show "Rund um den Michel" on NDR.
Yesterdays edition of the Hamburg based show was themed around "traces and tracing". Yago, a Hamburg based player and his friend were chased through town in a nice mission the TV team came up with - going deep down under the Elbe and high up to a bar with an excellent view over Hamburg as well as exploring an old Bunker.
In the tunnel they had to find out how deep it is at its deepest point - and surprisingly they could send their answer right away from down there. Which of course was a trick - in reality players have to get out of the tunnel until they can post the answer to the riddle since there is neither internet nor GPS reception down there.
By the way, this was the second time GPS Mission was on German TV - a few weeks ago it has been on 3Sat, in a short feature on Location Based Games which can be watched online.

If you take a look at the GPS-Mission map of Bremen, you´ll find quite a few missions that either make you play a gangster or a police officer.
