Nintendo are treating attendees to Cologne's Gamescom 2011 event to some Zelda goodness...

If you're near Cologne next month, you may want to consider dropping into the Cologne Trade Fair Center. The Gamescom trade fair is coming back into town for its third year, and Nintendo will be on the scene with its Legend of Zelda 25th anniversary celebrations.

As well as having playable demos of The Legend of Zelda: Ocarina of Time 3D and the upcoming Wii swansong Skyward Sword, there will also be a Zelda cosplay gathering for the slightly more creative attendees. The first 111 people there will also be given limited edition T-Shirts.

Also expected are a host of demos that were playable at this year's E3, an autograph session with the 'voice of Mario' Charles Martinet and good old Mario Kart Wii tournament.

Gamescom runs from August 17th to the 21st. You can buy tickets from the official website here.
