Career add-ons for Microsoft Flight Simulator have become a proper genre at this point. We’ve covered everything from the logistics grind of NeoFly to the structured airline life of Fly The Line, and more recently the ambitious scope of Clear2Land and the schedule-driven approach of FlyHub.
Each one of those asks you to be a pilot building an honest career. FS Kingpin, heading into early access in June, has a rather different pitch: pick a criminal faction, fly contraband across real airports worldwide, and build an empire.
Yes, really.
Built solo by a developer, FS Kingpin is a standalone Windows companion app that connects to MSFS 2024 via SimConnect. It doesn’t touch your sim install, doesn’t require an account, and plays fully offline once downloaded. What it does is layer a full criminal career mode on top of whatever you were already doing in the sim, reading your flights, grading your landings, and feeding the results into a working contraband economy that spans the entire globe.
Four factions, one choice
Before you fly a single mission, you pick your faction. There are four: Los Halcones, a cartel based in Bogotá; the Marchetti Family, the mob operating out of Palermo; the Adamson Firm, a London-based criminal outfit; and Kuroda-Gumi, the yakuza, starting in Tokyo. Your choice sets your home airport, your starting country, and the order in which regions unlock as you progress. The developer says it’s a permanent decision unless you reset your career entirely.
The career itself spans 50 levels across three narrative arcs: The Mule at the low end, The Hustler in the middle, and The Kingpin in the late game. Each phase changes the nature of the missions and, according to the developer, the tone of the handler character who briefs you on runs. It’s a narrative layer that most flight sim career tools don’t even attempt.
The economy is the game
The central mechanic isn’t just flying from A to B. FS Kingpin operates a dynamic black market economy divided into five global price zones. The idea is that cocaine is cheap where it’s produced, luxury contraband peaks in wealthy cities, and weapons fetch more the further from the factory they travel. The market shifts daily, so yesterday’s optimal route won’t necessarily be today’s.
There are 47 tradeable commodities across five tiers, from marijuana and hash at the street level up to black-ops shipments at the top end. The tier you’re working with determines both the payout and the consequence of failure.
Missions generate procedurally based on wherever you’ve parked your aircraft. Contracts scale with your level, from 20-nautical-mile bush strip hops to 2,000-nautical-mile intercontinental hauls. Optional modifiers let you take on harder conditions for an XP bonus: fly at night, stay below a set AGL ceiling the whole way, or push through rough weather for an extra 20-25% on top.
Build the organisation, defend the territory
Beyond the flying itself, FS Kingpin has a crew management system. You recruit roles including soldiers, lookouts, accountants, lawyers and regional bosses, each providing stacking bonuses to your operation. The developer notes that crew loyalty drifts over time, and informants are a possibility, so it’s not a static ledger.
You can also build drug labs at airports you control, producing weed, cocaine or MDMA on a real-time tick that continues even while the app is closed. And you’ll need to actively defend your territory, because five AI rival factions, Los Cuervos, Cartel del Golfo, La Sombra, Los Diablos, and Ndrangheta, expand and contest airports whether you’re playing or not.
Works with your existing aircraft
Crucially for a sim community with deeply invested hangars, FS Kingpin is aircraft-agnostic. It reads whatever MSFS reports and slots the aircraft into one of six classes, from Light Single to Heavy Airliner. Payware, freeware, and default aircraft all work automatically, with custom mappings available if the auto-detect misreads anything.
Early access
FS Kingpin launches in early access on Windows in June 2026, priced at $25 as a one-time purchase. The developer says the full 50-level career will be playable from day one, with balance passes, expanded dialogue, additional contraband content, and deeper rival faction simulation planned for the 1.0 release, targeting roughly six to twelve months after launch. All updates through 1.0 are included at no extra cost, and there are no subscriptions or in-app purchases.
