Saga CEO Rebecca Liao Explores AI Agents for Mobile Game Engagement

Rebecca Liao, co-founder and CEO of Saga, recently hosted the Sidekick event at GDC 2025, where she unveiled the company's latest advancements in AI agents for gaming. Saga, primarily known as a blockchain protocol, is now leveraging AI to enhance user acquisition (UA) and retention in mobile games.

Key Announcements

• AI-Powered Game Characters: Saga introduced AI agents for existing games, including Titanus from Hero Hunters, marking the first mobile game character to become an interactive AI agent.
• Partnerships: Collaborations with major IPs like Disney XD Latam (Karl) and OV Entertainment (Shalune from Metaphora) were announced.
• AI Mods Platform: A new platform compatible with games like Fortnite, Elden Ring, and Minecraft was revealed, featuring AI-generated in-game assets.

Titanus, a character from Hero Hunters, is now an interactive AI agent.

How AI Agents Work

AI agents are autonomous programs that can perceive their environment, make decisions, and interact with players. Unlike traditional NPCs, these agents evolve over time, learning from player interactions and game lore. For example, Titanus was trained on Hero Hunters' gameplay and lore, making its interactions feel natural.

"This is not a chatbot! This can think for itself," said Liao. "It’s been trained on the gameplay and the lore of the character, but so much of the interaction feels natural because it’s absorbing conversations it’s had with the fans."

Business Benefits

Liao emphasized the cost-effectiveness of AI agents compared to traditional marketing campaigns:

• Cheaper UA: AI agents reduce the need for expensive ad campaigns on platforms like Meta and TikTok.
• Improved Retention: Blockchain-powered games using Saga's infrastructure have shown higher retention rates, with players staying engaged for 3-6 months.
