PUBG Ally shipped to 141 countries and measured what broke trust

Krafton added an AI teammate called PUBG Ally to one of the world's largest live games. Players in 141 countries used it. The team collected real behavioral data at scale, using a careful methodology, on how players responded to an agent that spoke, acted, and made decisions alongside them in a high-stakes environment. Three design tensions stood out. Latency mattered more than accuracy in moments of action: a slow correct answer was worse than a fast approximate one. Trust grew when players could see what the agent was about to do, not when the agent performed well. Players who understood the agent's next move gave it more latitude than players who saw the same outcomes with no warning. Identity held weight too: players treated the agent as a teammate when it had a stable character, and as a broken tool when it did not. For teams designing agent products, this deployment offers real-world evidence that lab studies cannot. The findings on latency, trust-building, and agent identity come from a population that did not sign up for an AI experiment. They came to play a game. The agent had to earn its place in the team.
