Together on Mars Update - 4 Player Co-op Beta is Here!

Hello everyone!

Today is probably the biggest day for Blossom since launch.

After many months of work, I'm excited to finally say that 4-player online co-op is now available in the Beta branch!

This is a public beta test before the update releases to everyone on the main branch. If you'd like to help test co-op and share feedback, I'd love to have you join.

Terraform Mars Together

You can now invite up to 3 friends into your world and terraform Mars together.

Build bases, explore, mine, drive vehicles, automate factories, discover new life, and complete the entire game together from start to finish.

Best of all, your existing saves still work.

If you've already spent dozens of hours building your world, simply load your save and open it to co-op. No restarting required.

Up to 4 Players

Co-op isn't a separate mode. It's the full Blossom experience.

Everything is shared:

• Buildings
• Terraform progression
• Power and water networks
• Research and objectives
• Machines and automation
• Vehicles
• The story and ending

Each player keeps their own backpack, equipment, appearance, and achievements while working together on the same world.

You can also customize your own Blossom's colors so everyone is easy to recognize.

Existing Saves Are Compatible

Your current saves are fully compatible.

Continue playing solo exactly as before, or invite friends into your existing world at any time.

If you prefer playing alone, don't worry. Single-player is completely unchanged.

How to Join the Beta

To access the co-op update:

1. Right-click Blossom: The Seed of Life in your Steam Library.
2. Select Properties.
3. Open the Betas tab.
4. Choose the Co-op Beta branch from the dropdown.
5. Steam will automatically download the update.

The full release will come to the main branch once beta testing is complete.

Found a Bug?

This is a beta, so you may run into bugs or unexpected issues while playing.

If you do, please use the in-game Feedback button in the pause menu to report them.

It automatically includes useful information such as your save file, logs, and system details, making it much easier for me to investigate and fix the issue quickly.

Every report helps make the full 2.0 release as polished as possible. Thank you!

Thank You

This has easily been the biggest and most challenging update I've worked on for Blossom.

Thank you to everyone who has supported the game so far. Your feedback, bug reports, reviews, and suggestions have helped shape every update, and they'll help make this one even better.

I can't wait to see the bases, factories, and adventures you create together.

See you on Mars.
