The people in charge have defunded hospitals so you decide to help. With your squad of volunteer medics, plan your tactics, schedule actions and optimize the team strategy to heal as many patients as possible. 1-8 players, only the host needs to have the game installed. Modding support integrated.
The patients arriving at Lonchester hospital have ongoing medical and life issues. You can help them by administering the right kind of medicines. They will gradually reveal and share aspects of their lives with you.
Coordinate your volunteer medical squad, schedule your turns and enjoy figuring out the optimal strategy to heal each patient. Tabletop gamers might know this as "Action Programming". Decide which hospital equipment to upgrade and where to place items for maximum efficiency.

Similar to the Jackbox series of games, only the host player needs to have the game installed. Guest players join an online session by entering a 4-digit room code on their phone, PC or any other device with a web browser. Once connected to a game session, each player controls a character and/or becomes a dialogue writer via their connected device.
You can control multiple players/characters from a single device if you want to:



Co OPERATION: MultiTurn is not *exactly* like any other game, so it’s quite difficult to say “it’s like game X but combined with game Y”. Having said that, if you enjoy tactical games where you have to think ahead, like Into the Breach, Wargroove, Shogun Showdown or Monster Train, you’ll probably enjoy this game. Co OPERATION: MultiTurn stands out when you play it with some co-op buddies. Coming up with clever tactics together and working out optimal strategies as a team is a really nice feeling. It’s typically pretty funny when your plans go wrong too.

We’re trying to make a multiplayer experience that helps people feel emotionally connected to each other. That’s (kind of) been scientifically proven! Groups of Masters level psychology students at Basel University evaluated an early demo and all agreed that it positively affects relationships. Here’s a quote from one assessor: “We felt that our relationship as a group was strengthened and we definitely got to know each other much better because of the game.”
Running hospitals is expensive. A clever bean in central government decided that tearing up requirements for medical qualifications would help. Volunteers are now welcome… throughout the country?! 🤷 You decide to enroll and help your local hospital. Find out what the patients need and form a strategy to help them. The more coordinated your team is, the more people you can heal!

To play online, screen-share your PC screen while on a video call. Guests join a session by entering the room-code on their web browser/phone. It doesn't really matter if one player has internet lag, the gameplay is designed so that lag doesn’t affect the fun.
We’re actively developing Co OPERATION: Multiturn. It was in closed-testing on Itch for [far too long] before we brought the demo to Steam. We appreciate all our player feedback and let it guide our plans. Many features were born from votes on our Discord and mailing list. We also have an ongoing collaboration with Plymouth University, with students from Plymouth making mods for Co OPERATION: MultiTurn. You can find them from the in-game modding menu. Documentation on how to make mods is also in-game.
