Gnome Knocker is a platformer game (idea) for the Xbox 360 (as of 2009), which launched a massive craze into the mass media.
Gnome Knocker tells the story of Jimmy and Serenity, two fraternal twins who come in possession of the mysterious book, the Gnomonicon, which they find in the depths of their attic. They read it and release many evil gnomes into the world, which are lead by a Gnoman Biglie who instantly proclaims himself King of the Gnomes. With a snap of his fingers after a brief confrontation with the twins, Gnoman disappears with all of his gnome minions. Outside the window; however, they see what looks like lawn gnomes destroying their backyard. Thier mother blames them for this and sends them off to clean it, but the only way to do that is to stop the gnomes.
Jimmy and Serenity travel through various adventures, trying to stop all of the Gnomes. They start at the school library where they find a spell that allows them to return super-powerful gnomes back into the Gnomonicon. At the end of each episode, one of them fights another Boss Gnome, which usually involves some strategy to beat.
Soon the twins traverse the Gnome City, escape through the Gnome Mines, and enter the Gnome Castle where the battle with Gnoman Biglie is fought. He casts many spells, and as the battle is going strong, Gnoman makes the entire tower fall, hoping that whichever twin he is battling will fall with it. When the twin gets to the bottom, the battle finishes with one amazing finale. It is here that Gnoman is defeated and brought back into the Gnomonicon.
But as the twin leaves the castle to meet the other one coming from the Gnome City, they toss the Gnomonicon into the surrounding woods. Sometime later, an old and disfigured hand grabs the Gnomonicon, possibly spawning a sequel, and ending the game.
Gnome Knocker is a basic platformer, in which the player defeats enemies, finds weapons, and uses power-ups. The left thumbstick allows the player to move, while the right thumbstick lets the player look around. The right trigger allows the player to use a weapon, or their fist if they possess no weapon, while the left trigger allows the player to use a shield (if the player possesses one). The A button allows the player to jump. The X, Y, and B buttons let the player use one power-up, since only three can be held at one time. The D-pad is used to select a weapon, since only four can be set to quick access.
Gnome Knocker has several power-ups, which each take the form of a yard tool or an outdoors toy. The most common weapons are rakes and Frizbees.
Yes, but it is lemon flavoured!
The game was universally panned by critics. IGN gave it a 1.5 out of 10 stating that "I would have more fun rubbing my balls against barb wire than playing this game". GameSpot gave it a 2.3.
