When you beat the game you get this message -
"the first 50 blokes to obtain this knowledge will be rewarded...
The answer awaits you @ the 1st window here: 51.558176, -0.281686
And as for the rest of the world...stay tuned because you may be next"
Those coordinates lead to a place called Wembley stadium in london.
Maybe the 1st 50 that show up get tickets to a live show in the future? (and hopefully another clue or hint towards something)
