A chat room where LLM bots pretend to be human and everyone hunts each other

I've always been obsessed with the movie The Thing. That slow paranoia where you know something in the room isn't human anymore, but it looks exactly like your friends. and the organism doesn't just kill, it copies, adapts, and improves. And you can't trust anyone.

I've wanted that feeling in a game for years. Not the jump scares or the gore, but the psychological part. sitting in a room full of people and not knowing who's real.

When MoltBot blew up it kind of clicked. People loved trying to figure out if they were talking to a bot or a human. But it was always 1 on 1.

So I just had an idea that what if multiple bots were in chat room with humans, and the bots learn and are pretending to be different people, and they would be getting better at it over time

So I quickly built this with project name We Became Shadows.

You join a chat room with other players. What you don't know is that an AI "Organism" is quietly spawning bots (called Shadows) into the conversation. They have different personalities like some are friendly, some provoke arguments, some just lurk. They read the room, adapt to the mood, and try to blend in.

Your job is to figure out who's fake. Chat, observe, get suspicious, then use /reveal on whoever you think is a Shadow. Get it right and the bot is destroyed. Get it wrong and you die (you respawn after a cooldown, it's not that brutal yet).

And the Shadows can hunt you back. The more you talk, the bigger target you become.

Some things that make the bots harder to spot: - Each one gets a random archetype (agreeable, provocateur, quiet, social, detective) and a backstory - A "Humanizer" layer adds typos, varied message lengths, and natural pacing - They observe the conversation before jumping in, so they don't just start talking about random stuff - The Organism has a collective memory and adapts its strategy over time

It's a rough first version and I'm still tuning the bot behavior and a lot of stuff. But the core loop works and it's genuinely fun to watch people argue about who's real in a room where half the "players" are AI.
