How to Fish multiplayer runs in 1-4 player co-op where teammates can slap revive each other after a knockout. The co-op loop covers every island gate, the per-island Boss fights, and the Casino ship mini-games, and seagull interference remains active in shared sessions. Solo play is supported with the same progression loop, but co-op is the intended way to handle slap revive chains on the harder Boss phases. Cross-play plans are not announced as of 2026-09-01.
How to Fish multiplayer basics
The Steam store page describes How to Fish as a 1-4 player co-op physics fishing sim, and the co-op loop is the launch framing for the entire game. gamingpromax's launch review confirms that 1-4 player parties are the intended way to play, with solo runs supported as a valid fallback. ### Party size and host model Parties can range from solo up to a 4-player crew. There is no required party size for any island gate, so players can scale the difficulty by simply adjusting who joins. The host runs the session and gate unlocks credit the whole party regardless of who lands the final hit. ### Session types Sessions cover the standard 5-island progression run, dedicated Boss practice runs, and Casino ship mini-game sessions on the boat. Each session type uses the same slap revive rules and seagull interference described in the launch coverage.
Slap revive mechanic
Slap revive is the headline co-op mechanic. When a teammate is knocked out by a fish, Boss attack, or environmental hazard, an alive teammate can run to them and use the slap input to bring them back into the run. ### Knockout conditions Knockouts happen when a teammate's health is depleted by a fish charge, Boss attack, slap-from-behind by a teammate (accidental), or seagull collision. Knockouts are recoverable via slap revive rather than permanent, so the run continues without respawn timers. ### Slap revive rules The revive is a directional input within a short range of the downed teammate. Revives do not consume resources but do leave the reviving player briefly stationary, which creates a small risk window. Multi-knockout chains are common on the harder Boss phases, which is why co-op is the intended way to clear those fights.
Seagull interference in How to Fish multiplayer
Seagull interference is the environmental hazard that knocks players out of position, disrupts projectile physics, and triggers slap revive chains. The hazard remains active in shared co-op sessions and is one of the main reasons players should plan their shot timing around the gull wave. ### How seagulls affect shots Seagulls collide with mid-air targets and break chain shots, so co-op teams benefit from one teammate drawing the gull wave while another lines up the trick shot. The [trick shots](/trick-shots/) guide pairs with this rule because chain shots are the highest payoff pattern and the gull wave is the highest disruption risk. ### Seagull mitigation in co-op The simplest mitigation is positioning so the gull wave is on the opposite side of the target from the shooting line. Co-op crews can stagger this naturally because each player can act as a separate decoy during a trick shot attempt.
Casino ship, cross-play, and Steam Deck co-op
### Casino ship co-op context The Casino ship mini-games (roulette and slots) are part of the loop and are playable in co-op sessions. The ship acts as a social hub between island runs and is the natural place to spend currency earned from trick shots and Boss clears. ### Why the Casino ship matters for co-op Co-op crews can use the Casino ship to redistribute currency before the next island, gamble for bonus multipliers, and reset between Boss phases. The Casino ship context reinforces that co-op is the intended way to play because the social space is built around a party rather than a solo player. ### Cross-play status Cross-play plans are not announced as of 2026-09-01. The Steam store page lists the launch as Windows-only on Steam, and Dazed Games has not confirmed whether console versions, console cross-play, or Steam Remote Play pooling will be supported post-launch. ### Controller and Steam Deck co-op Controller support is part of the launch build per the Steam store page, and the [Steam Deck verification label](/release/) confirms the game runs on Steam Deck hardware at launch. Local co-op is the most natural way to bring a second player into a Steam Deck session, and Steam Remote Play is the documented fallback for players who want to bridge two devices into one shared session. ### Steam Deck session tips On Steam Deck the slap revive input maps to a controller face button by default, and the seagull interference reads clearly on the smaller screen because the gull wave is visually distinct. Players targeting the harder Boss phases on Steam Deck should plan shorter sessions because the controller layout favors sustained aim rather than rapid hot-swapping. ### Local co-op party setup Local co-op is the simplest party setup because there is no session hosting step beyond plugging in a second controller. The Casino ship mini-games and the 5-island progression both support local co-op out of the box, and the slap revive mechanic works identically across local and remote sessions. ### Session etiquette and progression sharing Co-op sessions share the island gate unlocks and the trick shot achievement progress across the whole party, so the etiquette rules are simple: revive downed teammates, share trick shot opportunities, and let the host manage gate transitions. Sessions that follow these rules consistently finish the 5-island progression faster than solo runs because the slap revive mechanic removes the most common solo failure mode.
