Truck-kun is Steam Next Fest’s strangest mix of GTA and Crazy Taxi

Steam Next Fest always has a few demos that make you stop for the name alone. Truck-kun is Supporting Me from Another World?! is one of them. It sounds like a joke someone made in a group chat, then Strange Scaffold actually turned it into a driving game.

You are a delivery truck, you hit people, and those people get sent to a fantasy world where they help an office worker trapped in an isekai adventure. It is dumb in the right way, but the demo works because the game treats that joke like a full system instead of a quick punchline.

The Steam Next Fest demo is live now, ahead of the full release on July 29, 2026. Strange Scaffold is developing the game, and Frosty Pop is publishing it for PC and Xbox Series X|S.

The story starts with Carissa Ward, who is about to begin a new job in Wenvale. Then a delivery truck hits her and sends her to Talinfold, a fantasy world filled with monsters, magic, and the usual isekai problems.

Players control the truck in the real world while Carissa tries to survive in the other world. Every run has you driving through town, making deliveries, escaping police, hitting targets, and sending more people into Talinfold so Carissa can gain XP and stars.

The game has the speed and pressure of Crazy Taxi, but the streets get ugly much faster. You are not calmly driving passengers to a destination. You are smashing through town, cutting across roads, hitting jumps, and trying to finish objectives while police cars chase you.

There is a clear Grand Theft Auto flavor in how quickly normal driving turns into a public disaster. Traffic becomes a problem, fences become suggestions, and the best route is usually the one that causes the most damage.

The truck feels heavy, it does not move like a sports car, and the first few minutes can feel rough if you expect clean arcade handling. Once the weight starts to make sense, the clumsy movement becomes part of the comedy.

The game could have been thin if it only asked players to hit people with a truck. Carissa gives the chaos a clearer purpose. She knows she has been dragged into a ridiculous fantasy setup, and her goal is to get strong enough to return home.

That means the real-world driving and the fantasy adventure are connected. You cause problems in Wenvale, and Carissa benefits from them in Talinfold. The more useful people you send over, the better chance she has against the Skeleton King and the world keeping her there.

It is still silly, but it is not random. The game gives each crash a reason, which helps the joke last beyond the first laugh.

Truck-kun is Supporting Me from Another World?! launches on July 29, so the demo has one job right now. It needs to make people laugh, prove the driving works, and show that the joke can carry a full game.

It is not trying to look polished or serious. It wants players to drive badly, cause trouble, and somehow help someone survive a fantasy world by making the worst choices possible.

For anyone looking through Steam Next Fest for something different, this is one of the easiest demos to notice. You get in the truck, the town becomes unsafe, and every bad turn might still count as progress.
