We’re back with another devlog to keep you in the loop as we continue improving and expanding Co-Op mode. There’s some great news this time — a long-awaited feature has finally made its way into the game… and it changes a lot!
We’re happy to confirm that the Tech Tree now works in Co-Op mode — and it’s a game changer!
Players can now earn experience and unlock new technologies together, but it also revealed how many systems are interconnected — scanning, drilling, growing plants, recycling, and even sleeping can all impact tech point generation.
We’ve already implemented the core synchronization and fixed several edge cases — like points only going to the host, or desynced XP values between players. We’re still refining balancing and interactions, but overall… it's working, and it’s fun!
This also means Co-Op is feeling more like a full-featured game mode now — not just a sandbox playground.
We’ve addressed a broad range of issues in the past week, including:
Stuck players after respawn or save/load scenarios
Invisible players, broken interactions or ghost items
Desynced incubators, plants growing at different speeds
Issues with grinding, planting, or harvesting mechanics in multiplayer
Camera bugs, incorrect UI states, or “skybox” glitches
We’re still working on polishing more subtle bugs — like occasional desyncs with cables or panels not updating correctly for all players. Some systems are being reworked to better support Co-Op logic long-term.
We’re inching closer to opening up multiplayer testing to more players. Once internal builds reach the stability we’re aiming for, we’ll begin inviting groups to participate in public tests. As before, Co-Op will eventually launch as a free update for all owners of the game.
The Steam Sale is live, and Occupy Mars is currently 40 % off. If you’ve been thinking about grabbing the game — or gifting it to a friend you’d like to explore Mars with — now’s the perfect moment.
Every week we’re getting closer to completing the Co-Op upgrade. It’s a lot of work behind the scenes, but your feedback, patience and enthusiasm make it absolutely worth it.
We’ll be back soon with more news — stay safe, stay curious, and keep watching the Red Planet.
