About
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:
Play in single-player mode or
Share your device with a co-op buddy.
Turn-based and grid-based.
In single player you control two characters.
Maximum of 8 players in multiplayer mode.
Every round, patients lose health - heal them by using an optimal amount of turns.
After earning money from healed patients, decide which hospital equipment to buy.
Vote on where to place purchased and upgraded hospital equipment.
Improve your patient satisfaction scores and rank to unlock more hospital wards.
Deep modding integration: play other people's mods or make your own.
You can have up to 4 volunteer medics and 4 dialogue writers.
Volunteer medics play-out the core tactical gameplay.
Dialogue writers type the speech-text for patients and medics which is fun for players who want to join a session but are more creative than strategic.
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.

Yes! I've been waiting for the release. Great party game that everyone can play!
I am having a wonderful time yelling at my roommates
This game is an incredibly fun puzzle game. It has the same ease of connectivity as a jack box game, while actually having a lot of depth in the game play. The levels/puzzles take quite a bit of planning to pull off correctly, but if you do, it's extremely satisfying. Having to time out placing patients, grabbing medicine, and using the medicine gives you a bit of a rush, as you sometimes get when completing a difficult puzzle. You can also fall into this really great flow state and then suddenly everything begins to fall in place. If you like the ease of use of a jackbox party pack game, but want something with a bit more meat on its bones, I can't recommend this game enough. Had a blast, and absolutely plan to come back this game again.
Co OPERATION: MultiTurn is a brilliantly accessible cooperative party game that turns simple simultaneous actions into hilariously chaotic teamwork challenges. With up to 8 players joining instantly from their phones, minimal rules, and short replayable levels, the real fun comes from communicating plans, adapting when everything goes sideways, and collectively improving run after run. It captures the spirit of a great cooperative board game while removing setup friction, making it ideal for families, friend groups, classrooms, work events, and stream communities alike. 🟢 Up to 8 players 🟢 Performs great on both Steam Deck and PC 🟢 Join instantly on any connected device via browser (Jackbox-style ease) 🟢 Simultaneous turns = no waiting, no downtime, constant engagement 🟢 Extremely simple actions (move, throw, use, wait - in four directions) make teaching effortless 🟢 Truly cooperative. Communication and coordination are the key challenges and core fun 🟢 Quick levels encourage “one more try but better” teamwork loops 🟢 Item unlocks and deploy choices add strategic variety 🟢 Players can swap in/out easily between quick levels, perfect for gatherings 🟢 Quirky, charming presentation 🟢 Clear readable art and presentation style; no visual noise 🟢 Exceptionally friendly and responsive dev team and positive community (check out their awesome Discord!) 🟢 Great for streaming, classrooms, work events or any team-building activities 🟢 Feels like a polished co-op board game without the setup or rule overhead DEEP DIVE (aka the much longer version) [b]Co OPERATION: MultiTurn is one of those rare cooperative experiences that feels immediately approachable while still offering depth in the places that matter most, namely communication, coordination, and shared problem-solving.[/b] [b]A big win here is accessibility[/b]. With up to 8 players able to join from any device via connecting to a website (sorta like Jackbox games), getting people into a session is quick, easy and painless. There is no controller juggling, no installs for guests, no barrier to entry. If someone can open a browser, they can play. That alone makes it an easy recommendation for parties, family gatherings, classrooms, or team-building events. [b]Mechanically, the game keeps things intentionally clean[/b]. Players choose from a small set of actions (move, throw, use, or wait) across four directions, which makes the rules trivial to learn and teach. Gameplay is incredibly accessible even for friends and family who may have mobility or fine motor-skill challenges, etc. [b]The real fun of the game emerges from how those simple inputs collide once everyone’s simultaneous turns resolve[/b]. There is no waiting, no downtime, and none of the pacing drag that can sometimes come with turn-based systems. Everyone commits actions at once, which keeps energy high and makes the game especially friendly for groups that thrive on constant engagement. [b]Because turns resolve together, communication becomes the core skill[/b]. Each attempt at the game's many levels turns into a lively exercise in expressing intent, negotiating chaos, and adapting when plans inevitably unravel. It creates that cooperative “let’s try that again, but see if we can do it better” loop that some of the best Jackbox/party games and strong co-op board games capture so well. Different friend groups even end up solving the same levels in wildly different ways, which makes replaying content feel less like repetition and more like experimentation in team dynamics. Also... only you need to know which set of friends/coworkers communicates best right? ;) haha. [b]Purchasable items with wacky fun abilities and those inventory decisions help mix things up.[/b] Groups can discuss what tools to invest in for specific levels, try new combinations, and discover emergent strategies together. [b]Importantly, the design is genuinely cooperative[/b]. Lone-wolf play offers no advantage, and success consistently rewards the best, tight collaboration. [b]Session flexibility is another standout feature[/b]. Levels are short, players can swap in and out easily, and the game scales comfortably up to 8 participants, making it viable for full gatherings rather than only small groups. It carries the feel of a polished cooperative board game without any setup overhead, rules management, or component handling. [b]Presentation supports the experience well[/b]. The art style is distinct and expressive without obscuring clarity, humor lands through both gameplay and narrative quirks, and overall readability of levels remains strong. [b]Nails stability, reliability, and customizability right out of the gate.[/b] The game has reaped the reward of its extended testing period, engaged and responsive devs, and active community involvement, which shows in smooth performance across devices and thoughtful options like adjustable actions-per-turn to match group preference. [b]Equally notable is the surrounding community and developer presence[/b]. The team is active, welcoming, and visibly player-first in their approach. Feedback is encouraged, discussion is open, and the Discord community reflects the cooperative spirit of the game itself. It is one of the more positive and engaged environments I have seen around a multiplayer title. [b]Co_OPERATION: MultiTurn also translates extremely well to streaming and organized events[/b]. Whether for content creators wanting audience interaction or workplaces looking for collaborative exercises, the ability to control visibility of teammate actions creates fun opportunities for both transparency and suspense. [b]Overall, this feels like a game built with a clear understanding of what makes cooperative play memorable: low friction entry, simple verbs, emergent coordination challenges, and a shared drive to improve together. For groups that enjoy laughing through chaos while gradually tightening teamwork, this is an easy, TOP, MUST PLAY recommendation.[/b]
Really enjoyed Cooperation. It's something completely different, and whilst I've only played it two player so far we're already lining up a bigger session with friends. Really recommend giving it a try, it's got decent strategy in there without being overly complicated and it's wrapped up in a nice fun "theme hospital"-ish package.
Great game to play with friends and quite different from other co-op games. You really have to communicate with the other players and as we all know human communication leads to lots of misunderstanding as well which leads to some hilarious situations in this game! :D
I recommend this game if you want to have a planning-based cooperation game with friends. Only one of you needs a copy, you play it jackbox-style with a browser as your controller. So imagine 4 players on a grid, like a tactics game. Objective is to move patients to beds and medicines to patients. We plan our turns, 4 moves at a time, e.g. North, grab medicine, east, use medicine. We can also throw patients and medicine, passing it to other players. If the patients spend too many turns un-medicated, that's very bad. It's simple in theory but obstacles and tight turn-based timers make it challenging, so planning co-operation is key. It often became necessary for friend to throw me medicine across the room cuz it would take me too long to walk across the room to get it. Same for patients. Throw them to your friend to get them in a bed faster!
