Description
Bside is a cozy multiplayer character simulator where your BIIBIT grows, explores, builds relationships, and develops a life of its own.
Design your BIIBIT, shape their personality and appearance, and watch them grow through stories, adventures, friendships, and everyday moments.
Whether you're exploring Adventures, creating stories in Playground, or chatting with your BIIBIT, every experience helps shape who they become. Every conversation, every gift you give, and every choice you make leaves a lasting mark on their journey.
At its core, Bside is about creativity, self-expression, companionship, and sharing your characters with others. Create the BIIBIT you've always imagined, tell their story, meet new friends, and watch your relationship grow over time.
Your BIIBIT remembers your conversations, reacts to your choices, and grows through the experiences you share. AI powers character conversations and optional creative tools, while your BIIBIT's personality, stories, Bonds, progression, and adventures are shaped by you.
