GameBot Inc. deployed a supervised learning (SL)-based AI solution for Mobile Legends: Bang Bang (MLBB). We developed highly human-like game bots that stably match player capabilities across all skill levels. Beyond adaptive combat performance, our framework enables autonomous AI chat functionality, allowing in-game bots to actively respond to player pings, commands and text interactions in real time. The upgraded interactive experience effectively boosts player immersion and stickiness. The project delivered outstanding measurable results: achieving over 6% retention growth among less active users, and bringing a more than 50% increase in player engagement for mid and low-tier players after the launch of AI chat features.
