SentientMobs 2.2.0

Every Mob Has a Mind. Every Group Has a Strategy.

The biggest AI update in SentientMobs history is here.

SentientMobs 2.2.0 introduces three major AI pillars that fundamentally change how mobs behave:

🧠 Personality 🤝 Squads 📖 Memory

Mobs are no longer predictable machines that blindly follow scripted behavior. They now develop unique personalities, coordinate with allies, remember previous encounters, track danger, and react differently based on their experiences.

The result is a world that feels more alive, dynamic, and dangerous than ever before.
