Half-Life: Alyx - The Gnome Chompski Run

Sit back, relax. It's time to regale you the wondrous tale of Valve's most iconic Gnome. Chompski is a recurring garden gnome in some of Valve's games. In Half-Life 2: Episode 2, he can be brought along the entire ride and stuffed in the rocket right at the end for a special achievement. In Left 4 Dead 2, he can be unlocked by scoring 750 points in the shooting gallery minigame, after which you must take him all the way to the Rescue vehicle. This humble garden gnome is no doubt one of the most coveted running gags for achievement mechanics.
