Last month The International 2015
became not only the largest Dota 2 tournament, but also the e-sport event with the biggest prize pool ever
, surpassing last year's event.
Now, the prize pool has reached the last stretch goal of $15 million, thereby unlocking the Immortal axe and a new comic. Since The International 2015 is scheduled to begin a month from now, on August 3rd, Valve could very well add another set of stretch goals to help boost the prize pool even further.
