We heard last month that Dota 2 is due to be previewed in a competitive tournament at August's Gamescom 2011 in Germany. In a new announcement on the official Dota 2 blog, Valve has now revealed the incredible details of this massive tournament. 16 of the world's top classic DotA teams will clash in a bid to win a staggering $1,000,000 US top prize. Confirmed commentator Tobi has been referenced as saying that the total prize pool is actually $1.6 million US, leaving a potential $600,000 for runner-up prizes. This tournament will be the first time Dota 2 is publicly shown, and every match will be streamed live across the internet in four languages. The five-day tournament will run between August 17th and August 21st.
