Half-Life 2 testers horsing around with physics props 'to make the 47th playthrough of the game more interesting' probably had no idea it would result in Gabe Newell launching a garden gnome into space 16 years later
"Little Rocket Man" is truly one of the greatest bits in videogame history—a challenging achievement in Half-Life 2: Episode 2 that requires you to carry a cherubic little garden gnome named «Gnome Chompski» through the entirety of the campaign and deposit the wee fellow on a rocket ship to another dimension in the final level. The Chompski achievement returned in several later Valve games, including Half-Life: Alyx. It reached apotheosis with Gabe Newell's 2020 IRL recreation, with a tangible Chompski launched into space as a fundraiser for a pediatric charity. And it all began with bored Valve QA testers messing around with physics props in Half-Life 2.
