As of right now you can now go and purchase a ticket to The International, Valve’s very own Dota 2 tournament sporting a massive $1.6 million prize pool, and then some thanks to the Interactive Compendium. If you want to be there in person between August 7th-11th, then you’re going to want to buy a ticket. They’re selling faster than a charging Spirit Breaker.

You can buy a ticket from here although expect the store to grind to a halt as everyone piles in for a ticket. Tickets go for $49.99 and the new Interactive Compendium sells for $9.99.
