Valve attending (only in business area)
Valve also powers a "wave" event:
You can go wild on the gamescom wave powered by valve. It is in the outdoor area, but don't worry, you won't even get wet. A rotating carpet gives you the feeling of truly surfing a wave. The gamescom wave powered by valve is right next to the beach and extends the beach area with another highlight. Grab yourself a board and surf the gamescom wave powered by valve.
