In the second installment, Half-Life 2: Episode Two, launching the gnome into space appropriately earned the player the Little Rocket Man achievement.
Gnome Chompski was introduced as a nondescript garden gnome in Valve's Half-Life 2. If a player carrying him to the final location of the game and locked him in a rocket, they could earn the Our Mutual Fiend achievement. For every viewer who tunes in to watch the stream, Newell will pledge $1 to the Pediatric Intensive Care Unit at Starship Children's Hospital in Auckland, New Zealand. Little Rocket Man Gnome Chompski is heading into space for charity, courtesy of Valve's Gabe Newell, as the easter egg of Half-Life 2 and Left 4 Dead fame will be launched in a rocket for real during Rocket Lab's upcoming Flight 16 mission.
