Dear Passengers, FLEXUS's Viral and Divisive PC Debut

Kyiv studio FLEXUS announced Dear Passengers on July 14, 2026, and the numbers moved fast. It's a physics-based online co-op game where one player flies a failing budget airline while everyone else works the cabin, and the studio says its Steam wishlist page cleared 500,000 additions within hours of the reveal. Co-founder Semyon Kozyura gave that figure to Ukrainian outlet dev.ua, and the page kept climbing to 700,000 wishlists in less than two days. The Game Awards' Instagram account shared the trailer, which passed 100,000 likes. For a team that has never shipped a PC title, that's a loud entrance.

The pitch is simple to explain, which is half its appeal. Before each flight, the crew picks which passengers and cargo to haul, and the most profitable loads bring the most chaos once you're airborne. One player sits in the cockpit while the others serve meals, calm furious passengers, fight turbulence that flings ragdoll bodies and luggage around the cabin, and sometimes shove an uncooperative flyer out the hatch. Cargo holds can hide live crocodiles. Bird strikes wreck engines mid-flight. Proximity chat runs through all of it, so a pilot yelling instructions nobody can hear over the noise is a scene the game generates on its own.

FLEXUS frames its whole design philosophy around one idea.

"We create a game that is fun. Every element of it — the design, the graphics, the sound, the trailer — is aimed at one goal: that moment when you laugh with your friends."

Then the mood shifted. Viewers spotted name tags in the trailer reading "Epst. J" and "PDaddy," which many read as nods to Jeffrey Epstein and Sean "Diddy" Combs. One of those matches an acronym for a European pilot training program, but developer messages on Discord encouraging more Epstein jokes turned a coincidence into a controversy. A FLEXUS developer later said on Discord that the team does not condone Epstein's actions.

An earlier FLEXUS job posting had asked for candidates experienced with generative AI for concept work, then was edited to cut the reference. The studio maintains the game contains no AI-generated assets, and the Steam page carries no AI disclosure, which Kotaku read as a point in the game's favor in a genre crowded with low-effort releases.

That genre is "friendslop," a label coined in March 2025 as an insult for cheap, social co-op games and since partly reclaimed by the developers who make them. PEAK is the anchor case: its devs said the climbing hit was never built to last forever, the studio rejects "friendslop" criticism, a later update where cannibalism shocks even half of the devs' team had to be walked back, the team told players to pirate their game over a Roblox clone, and Aggro Crab has since moved on to the forklift co-op game Crashout Crew.

Ukrainian studios are in this space too, including House of Morok's Carpathian survival game Peak or Die. Kotaku has already called Dear Passengers "Peak on an airplane," and the game lands alongside the year's other distinctive indie debuts, like the fake-OS mystery Desktop Explorer we reported on earlier.

What separates Dear Passengers from the fill-ins is the same thing that carried Meccha Chameleon to 15 million sales in under a month earlier this year: one premise you can explain in a sentence. A crew holding a doomed flight together over voice chat isn't a haunted-house reskin. FLEXUS earned some of this through its mobile catalog, with more than 300 million downloads across Tower Craft, Mow My Lawn, and Train Miner since 2020. Kozyura summed up the studio's approach to dev.ua in a line that fits the genre.

"Sometimes feelings matter more than metrics."

As someone who covers Ukrainian games, I want this one to land, because a Kyiv studio turning a mobile résumé into a viral PC debut through a full-scale invasion is a story worth telling. I keep circling the chaos, though, since escalating-disaster co-op is the exact chaos-timer energy that bounced my partner and me off Overcooked, and it's thin on the slow narrative I usually boot a game up for. What I want to see at the planned Gamescom demo is whether the physics hold across four players on different networks, because that's the part a trailer can't sell.

Dear Passengers is the first time FLEXUS has needed deterministic real-time physics to replicate identically on every client, and its entire prior catalog of idle and hyper-casual mobile games required none of that. Studios with far more PC experience have shipped physics co-op with broken sync. The feel-first instinct is right for this genre. Whether it survives contact with live netcode is the question FLEXUS answers at launch, not before.
