DeepMind AI uses teamwork to defeat human 'Quake III' players

After developing an AI system that can beat Go and chess, Google-owned DeepMind started tackling a different class of games: multiplayer ones, which usually require teamwork. In a paper published by Science, a group of DeepMind researchers have detailed how they designed an AI system that was able to master capture the flag mode in Quake III. The system uses "AI agents" to represent its players in the game, which can play with or against human opponents. DeepMind trained those agents with 450,000 rounds of capture the flag, which total four years of gameplay completed over the span of a few weeks. The AI agents started out doing random movements, but after playing again and again and again, they eventually figured out the strategies and techniques that work.
