Truck-kun is Supporting Me from Another World might be the weirdest Steam Next Fest demo I've played this year, but I wasn't ready for it to so neatly blend together the vibes of going on a vehicular Grand Theft Auto rampage with arcade-style Crazy Taxi deliveries and objective clearing. Despite the cutesy, anime-style graphics, your goal is to use your delivery truck to wreak absolute havoc across your seaside town. But, for a good cause. Sort of.
In Truck-kun's opening, you, a hapless delivery truck driver, accidentally run over corporate marketer Carissa just before her big promotion. In the style of an isekai anime or light novel, though, that means she's transported to a fantasy world of monsters and experience points – but also that she's now haunting you. She has the chance to resurrect in time for her promotion, but only if you can help her cheat her way through experience points as quickly as possible. How? By striking down more pedestrians, turning them into low-level monsters she can instantly destroy. It's the circle of isekai.
