OK but from what I’m understanding this isn’t a game, just a proof of concept?

Allow me to present…. The entire article;

“TeaserPlay has presented a concept for an open world Toy Story game created in Unreal Engine 5, which is reminiscent of Disney Interactive‘s 1995 side-scrolling platform game. The game allows players to control both Woody and Buzz Lightyear, with Buzz battling Evil Emperor Zurg. Various obstacles and enemies must be overcome in different stages mirroring the plot of the film. A highlight of the game includes a glimpse of the Pizza Planet Truck, resembling a 1978 Gyoza Mark VII Lite Hauler pickup truck.”
