Garden gnome (Fallout 3)

There are two types of garden gnomes in Fallout 3 and three in Fallout: New Vegas: They are useful only as Rock-It Launcher ammunition or as a decoration.
 * "Damaged" ones, which are fairly common
 * "Intact" ones, which are somewhat rare.
 * And the Evil gnome which is in Fallout: New Vegas only.

Intact Garden Gnome Locations

 * Traders outside of Rivet City may occasionally sell them.
 * Vault 101 - Outside of Butch's room after your father escapes
 * Broken Steel - Several can be found when playing through the main quest in Broken Steel.
 * Jury Street Metro Station - In front of a house near the Jury Street Metro Station. While standing at the gate of the fence around the radio tower nearby, it's the house to the east northeast, a stone's throw away.
 * Lincoln Memorial - On a shelf in the Lincoln Memorial. It is owned by the slavers, and stealing it will take away karma.
 * Megaton - One comes with the pre-War theme for your house in Megaton.
 * Olney Powerworks (Broken Steel) - In the bottom center of the map, through a corridor with 2 barrels inside that appears at first glance to be a dead end blocked by debris, in a small bathroom.
 * Robot Assembly (Mothership Zeta)- At the very end of the assembly line, at the top right corner of the map, on the other side of the Electronics Access Panel near a mini television.
 * SatCom Array NN-03d - Sixteen (16) tiny intact garden gnomes can be found (being used as chess pieces) inside the SatCom Array NN-03d tower.
 * Tenpenny Tower - At least two can be found in Tenpenny Tower.
 * Tranquility Lane - You can find a several in Tranquility Lane, but they are impossible to take out without console commands. A garden gnome is one of the items you have to activate to access the Failsafe.
 * Citadel - North of the Citadel is a collapsed bridge. On the western edge under the bridge is a raider camp. The gnome is under the bridge.
 * Mothership Zeta - One can be found among two damaged garden gnomes in the engineering core in the room with the bed and where Toshiro Kago can be found meditating.
 * Olney Powerworks (Broken Steel)- One can be found behind a bin that is next to an filing cabinet, in the room that is next to the Tesla coil. It is hard to see because it's in the corner of the room. The gnome is with a toy car and has a cigarette in its mouth.
 * The Mill (The Pitt)- One can be found on top of Everett's desk.
 * GNR Building Plaza In Three Dog's office, near a trash can.

Garden Gnome "Easter Egg" Locations

 * Broken Steel - Multiple Easter Eggs can be found involving intact garden gnomes, some of which are humorously interacting with a stuffed teddy bear.
 * In one they appear to be playing strip poker using metro tickets as cards with the teddy bear apparently being the girl.
 * There is a gnome with a camera in front of it which appears to be taking a picture of two teddy bears which are tied to the train line in the Presidential Metro with a sign between them reading "help us!".
 * Mobile Base Crawler
 * In a stall in the lower Launch Platform Base, a damaged garden gnome was apparently cutting up meat with a deathclaw hand.
 * Also in the lower Launch Platform Base there is a counter with a small gap down the center of it lengthwise and a red motor hanging above it. A garden gnome can be found in this gap, apparently bowling using a pool ball and 10 miniature milk bottles.
 * Olney Powerworks
 * In Old Olney Underground, after emerging from the sewer, there is a gnome drinking, smoking, and watching TV in a bathtub while a bear waits for him with a briefcase across the room by the door.
 * In the bottom center of the map, through a corridor with 2 barrels inside that appears at first glance to be a dead end blocked by debris, there is a small bathroom in which a teddy bear and an intact garden gnome are apparently playing a game of chess using milk and beer bottles as chess pieces. The gnome is smoking a cigarette.
 * In the room after you retrieve the Tesla coil, there is a gnome nestled in a corner behind a stack of books and clipboards with a cigarette and sunglasses holding a toy car.
 * Point Lookout
 * In the People's Bank of Point Lookout, there is a gnome located in the bottom left deposit box. It is a miniature intact garden gnome holding a mini plunger in its left hand and standing next to a mini toilet.
 * There are several found outside of Haley's Hardware (all damaged). There is one exceptionally large garden gnome to the right of the entrance to his store.
 * Robot Assembly Mothership Zeta - At the very end of the assembly line, at the top right corner of the map, on the other side of the Electronics Access Panel, is a teddy bear and miniature intact garden gnome sitting in front of a mini TV surrounded by a pack of cigarettes, a shotglass, and a bottle of vodka.
 * Seward Square - A giant damaged garden gnome standing roughly two times the size of an average garden gnome is standing in front of a house. It still has the usual weight of four pounds.
