RELEASE: //42 GoFish for MSFS 2024

Nov 21, 2025

By Ed Correia

Sometimes you need to remind yourself why you do this.

As you all (hopefully) know, we have been grinding away on ChasePlane and Flow for MSFS 2024, rethinking systems, and pushing hard on features that we are excited to bring and improve on. Whilst rewarding, it's intense work.

Somewhere along the way, we needed a breather and something to help us reenergise. Day after day of looking at the same code, loading in and out of the sim to test iterative builds was starting to wear us down. Don’t get me wrong, ChasePlane and Flow are exciting projects and will be delivered, but as they say, “a change is as good as a holiday.”

Along came GoFish.

What started as a small experiment quickly turned into a surprisingly refreshing experience. And honestly? It was exactly the kind of project we needed. We here at //42 are encouraged to build and work on things that make us happy. As I said at the start, we need to remember why we are doing this, and to make sure that we continue to enjoy this crazy passion of ours, we need to strike that balance between work and play.

GoFish is a relaxing add-on to MSFS 2024 built specifically for Avatar mode that lets you slow down between flights and cast a line into lakes, rivers, or coastal waters across North America, Europe, Oceania, and beyond. Landed near a remote Alaskan lake? Grab your rod. Parked your floatplane at a quiet dock? Grab your rod. You get the idea…and wait till you try it in VR!

Don’t worry, ChasePlane and Flow remain front and center in our path to MSFS 2024. But sometimes, great ideas happen when you step away for a moment, and we think you’ll enjoy this one.

GoFish will release first to our Club 42 members, followed later with a general public release, so you must be logged in to see an add to cart button.

Most importantly, GoFish will require you to be on the SU4 Beta. Our general public release for GoFish will happen once SU4 has gone public, and we are comfortable with overall stability.

GoFish

//42 GoFish brings a fully‑fledged, data‑driven fishing experience into Microsoft Flight Simulator 2024, built specifically for Avatar mode. Step out of the cockpit, walk down to the shore, and cast a line into lakes, rivers, or coastal waters across North America, Europe, Oceania, and beyond. GoFish turns the world’s waterways into your fishing playground, all without ever leaving the simulator.

Under the hood, GoFish uses a real species database powered by scientific occurrence data (OBIS + GBIF) and a custom WASM engine. Every catch is driven by where you are, the current month, time of day, and whether you’re in freshwater, saltwater, or brackish environments.

With over 200 distinct species, each with realistic habitats, sizes, seasons, and rarity, you’ll always have something new to discover as you explore the globe.

An integrated in‑sim EFB app (tablet-style interface) handles everything: starting/stopping fishing, choosing bait and line, managing reel and drag, and reviewing your catch history. Whether you’re a simmer who wants a relaxing activity between flights or a completionist hunting rare trophies, GoFish layers a friendly fishing game directly into MSFS 2024.

Built for Microsoft Flight Simulator 2024

Native package built for MSFS 2024 using the in-sim EFB panel. No external apps required.

Avatar Mode Fishing
Designed specifically to work in the sim’s Avatar mode: walk your avatar to the water, see a drop‑zone marker where your cast will land, and fish from shore, docks, or beaches.

Global Coverage with Regional Species
Location-aware system that updates “Available Fish at This Location” based on your latitude/longitude, supporting North American, European, Oceania waters, and more.

Over 200 Data‑Driven Species
200+ species, each with habitat (fresh/salt/brackish), seasonal activity by month, time‑of‑day preferences, realistic weight/length, and rarity.

Freshwater, Saltwater, and Brackish Ecosystems
Water type detection, influencing which species can appear and which baits are effective.

Real‑World Distribution Data
Species availability uses preprocessed OBIS + GBIF occurrence datasets, filtered specifically for gameplay, so regional fish actually show up where they belong.

Smart “Available Fish at This Location” Panel
Lists of species you can encounter at your current spot along with indications of what could be there in different conditions!

Full Tackle Box: Baits & Lines
Bait system with data‑driven effectiveness multipliers and target species; line system with monofilament, fluorocarbon, and braided lines, each tuned for habitat and fishing style.

Physics‑Based Line & Fight Model
WASM‑driven line physics including tension, elasticity, slack, cast distance, break strength, and visibility; visualized via in‑app Line Tension and Line Out meters.

Dynamic Fishing Controls
In‑sim sliders for cast distance, reel drag, and retrieval speed, along with fight states such as idle, casting, line out, bite, reeling, caught, and broken line.

Difficulty Modes
Easy, Medium, Hard difficulties that change bite timing and catch pacing, each maintaining its own separate catch history.

Optional Auto‑Reel Assistance
Auto‑Reel mode can automatically manage drag and line length during fights, making the experience accessible while still offering full manual control for advanced players.

Rich Catch History & Stats
Per‑difficulty catch history with total catches, unique species, total/average weight, biggest fish, most‑caught species, and sortable lists (by date, weight, length).

Unit and Control Customization
Metric/imperial toggle, fully configurable key/joystick bindings with multi‑input combos, and a built‑in “How to Fish” guide explaining Avatar workflow and controls.
