Gnome Chompski

Gnome Chompski is a garden gnome and improvised weapon exclusive to the Dark Carnival campaign. He made his debut in Valve's Half-Life 2: Episode Two as the Garden Gnome and is infamous for earning you the achievement "Little Rocket Man". In Left 4 Dead 2, he can be picked up by scoring over 750 points in the shooting gallery minigame at The Fairgrounds and must be taken all the way to the Rescue vehicle in The Concert to unlock the "Guardin' Gnome" Achievement. All players within the entire Dark Carnival campaign play-through will attain the achievement, dead or alive, so long as one Survivor makes it into the rescue chopper with Gnome Chompski in hand.
