The Dota 2 [official site] cooperative campaign Siltbreaker concluded with the launch of Act II on Friday. The campaign, which is only available to folks who buy Dota’s latest Battle Pass tournament sticker album, is a bit bum but it does at least now have an easier mode. Those who want treasures and cheevies can still grind their faces against Siltbreaker’s boring difficulty but girls who just wanna have fun can play in the easier ‘Adventure Mode’. It still won’t be good but it will be less of a chore. (more…)

Something very interesting happened in the world of Dota 2 this weekend, and it wasn't The International. (Although that was obviously pretty big too.) As reported by The Verge, a self-taught AI bot took on pro player Danil "Dendi" Ishutin of Natus Vincere—and won convincingly.
The bot was designed by OpenAI, a non-profit AI research company founded and funded by, among other people, Tesla and SpaceX guy Elon Musk, who shared his satisfaction with the outcome on Twitter.
And that's true, but only to a point. It turns out a few conditions heavily arranged the match in the bot's favor, meaning we don't have to worry about robots taking over competitive esports just yet.
The OpenAI game was played under a very specific set of rules: It was a 1v1 contest rather than 5v5, which dramatically reduces the complexity of the gameplay, and both the bot and Dendi played with the same hero, Shadow Fiend, who as this Verge analysis explains relies on "accurate timing and placement of his magical attack ability" to succeed—the type of precision that bots naturally excel at. In fact, that's the only type of game the bot is capable of playing.
The AI also had access to Dota's bot API, meaning that it would have access to information like the distance between characters, as well as hard-coded player "techniques." So while a human player has to learn and judge distances on the fly and react accordingly, bots can execute the appropriate attacks exactly, every time.
While that may appear to diminish the significance of the bot's win, Greg Brockman of OpenAI said that it remains a big deal because of the way the AI learned to play the game. Previously, bots have built their knowledge from records of past victories won by humans, but the Dota bot learned primarily through experience.
"You have this system that has just played against itself, and it has learned robust enough strategies to beat the top pros. That’s not something you should take for granted,” Brockman said. “And it’s a big question for any machine learning system: How does complexity get into the model? Where does it come from?"
The full story behind the AI victory won't really be known until a thorough analysis is released, but it is worth noting that once players were able to see the bot in action and got to know its tactics, they were able to compensate and beat it fairly handily. Even so, it's unquestionably a step on the path toward bigger and (maybe) better things, a point Musk mused on immediately after tweeting about the OpenAI's Dota 2 victory:
Dendi, who was a good sport about the competition, is on the same page.
