Co-op is part of the experience title and the official description. It is not a separate mode with published bonus rules.
What the listing confirms
- The description says "Play with your friends, CO-OP is available!"
- The experience server size is 6. That cap counts everyone in the server, friends and strangers.
- If the server is full, another friend cannot join that server.
- VIP server creation is off on the experience record, so there is no private-server switch to reserve the six slots.
- The description does not list a co-op-only reward or a solo penalty. Playing alone uses the same roll, build, steal, pet, and offline loop.
Voice chat and camera are marked not supported on the public listing.
Three places, one experience
The universe has three places:
| Place | Place id | What the record says |
|---|---|---|
| Build a Base & Steal Plants 🌱 [CO-OP] | 93801483388308 | The main listing, with the full description and a server size of 6 |
| Build a Base & Steal Plants 🌱 [New Players] | 75563752381270 | A place in the same experience. Its place description is empty |
| [Building Servers] Build a Base & Steal Plants 🌱 | 139166519351832 | A place in the same experience. Its place description is empty |
The New Players title is the reason to try that place on a first join. The game record does not spell out an automatic redirect, and it does not publish a separate player cap for that place. Building Servers is named and undescribed. Do not assume it is a creative-mode sandbox or a private base slot.
How to share a server
Join the main place, or the New Players place if you are starting, and have friends join while the server still shows open slots. Six includes anyone who loaded in before them. There is no confirmed group bonus on top of the normal loop, so a friend group still needs walls. Friends can steal from each other under the same escape rule as everyone else. Nothing in the description turns co-op into a shared plot.
