No. Project Tomorrow is single-player only, with no online co-op, local co-op or multiplayer of any kind. Its solo developer wants co-op too, but is concentrating on the single-player campaign for now and has not ruled it in or out.
Project Tomorrow, a terraforming and tower defense survival game from Advance Nine, entered Early Access on Steam on November 9, 2026. Co-op comes up often on its Steam forums, where a “We want Coop Online” thread has been running since May 2026. Here is where things stand.
What the Steam Store Page Lists
Project Tomorrow’s Steam features are Single-player, Steam Achievements, Full controller support, Steam Cloud, Save Anytime, Adjustable Difficulty and Family Sharing. There is no Online Co-op, Shared/Split Screen, LAN or Online PvP tag, which is how Steam marks multiplayer support.
Family Sharing does not add multiplayer. It lets someone in your Steam family play the game on their own account, in their own colony, not alongside you.
What the Developer Has Said About Co-op
The developer, Ryan, answers in the co-op thread directly. When players first asked, Ryan joked that “100% of the dev” wants it, then added: “I’m a solodev and 100% of me wants this too.”
Later in the same thread, Ryan set expectations:
“I want coop too but I’m concentrating on a kick butt single player campaign at the moment. Not ruling it out but I want to be realistic about what I achieve with my time at the moment.”
So co-op is not planned for any date, and it is not off the table either. Adding online play to a game built for one player is a big job for a single developer, and the stated priority during Early Access is content: “My next big priority is bringing you a new region and more content to explore,” Ryan wrote in the launch week patch notes.
What Early Access Adds Next
At launch, Project Tomorrow has three regions, 20 buildings, 75 items, 18 enemy types and 20 modifiers. On the forums, the developer has laid out what comes next:
- A new region with a jet, expected next month (December 2026).
- An endless mode, also expected next month, for players who want to keep fighting waves after a region’s objectives are done.
- More regions, buildings, enemies and ways to play through Early Access.
The plan is to stay in Early Access for 6 to 12 months, and Ryan has said the hope is for “closer to 6 than 12.” Co-op is not on that list, so if it is a must for you, waiting and watching the store page’s features is the safe move.
Playing With Friends Anyway
Without co-op, the closest thing to playing together is competing. The Modifier System, which unlocks after the tutorial region, lets you equip Challenges to make a region harder, and the more Challenges you equip, the higher your potential region score. Pick the same modifiers as a friend and compare scores.
