Indeed, NetDragon did pull off a show.
The beginning of the video was a slightly low perspective, moving down an old and dilapidated corridor.
The camera's movement was somewhat peculiar—it was almost utterly stable, moving very smoothly.
The audience followed this perspective to the end of the corridor and then turned left.
Enemy figures emerged in the distance. As soon as they appeared, half a gun appeared on screen, accompanied by a gunshot. The "player" successfully took down their enemies.
But quickly, more enemies appeared. The "player" was attacked, and the screen tilted back, directly falling out of the "body".
By this point, the audience realised: it was not the player themselves who was fighting, but a half-human-high battle robot that moved on tracks.
The camera then quickly pulled back, distancing from the battlefield, and the player finally appeared in the frame.
