What players are asking for
"pliss add coop online" is the busiest thread in the Steam discussions. Players The requests are specific:
- One player handling artillery and air strikes while another runs the ground fight.
- Each friend running their own base on the same map (a separate thread, "Coop with friend, each with his base").
- Playing as a group of friends, the way some already do in other co-op zombie strategy games.
Not everyone agrees. Replies argue the solo developer should finish the single-player game first, and one doubts a horde this size can be synced online at all. Players
Why it is a "maybe"
Ebbtide simulates a horde the store describes as "a million zombies, perhaps more" on one continuous map where nothing is auto-resolved. Official Keeping that many units in step across players is a much bigger job than a typical RTS skirmish, and it falls to one developer. That is our reading, not the developer's; the official line is simply that the focus is single-player and co-op is considered, not promised. Dev
If you want co-op, the developer asks for feedback on the official Discord. A +1 on the Steam thread is also visible to them.
FAQ
Is Ebbtide multiplayer?
No. Ebbtide is a single-player game. Steam lists only the Single-player category, and development is focused on the single-player experience.
Will Ebbtide have co-op?
Maybe, later. The developer said co-op "is being considered for a post-launch update, but I cannot promise support yet," and added that it is a feature they would personally love to add.
Will Ebbtide have PvP?
Nothing has been announced. A player suggestion thread asks for PvPvE, but the developer has not mentioned competitive modes.
Can I play Ebbtide with friends at launch?
Not on current plans. Launch is single-player; any co-op would be a post-launch update.
