Fre Quency

A rhythm series that doesn't depend on special peripherals. All that's needed is a Play Station 2 controller. Seriously. Each song has 6 main tracks (drums, guitar, etc.). On each track, there are a bunch of gems representing that track's instrument. Hitting all the gems on a track for two measures activates that track temporarily. Your job is to move around the tracks and hit all the gems to keep them all activated.

The first game was Frequency, followed by a sequel, Amplitude, both on the Play Station 2.

Made by Harmonix, who went on to make Guitar Hero and Rock Band.

The game provides examples of:

 * And Your Reward Is Clothes: the various "arenas" in which the songs can be played.
 * Competitive Multiplayer: And one of the first games to use the Play Station 2's online network adapter.
 * Crowning Music of Awesome, Ear Worm: Bonus song Luge Crash qualifies.
 * Cult Classic: Mostly due to low sales and a unique song library.
 * Difficult but Awesome: There isn't much better moments of euphoria than beating any of Frequency's harder songs on Expert mode.
 * Interface Screw: some of the powerups in multiplayer
 * Rhythm Game
 * Techno: The majority of the music library, though some songs dip into the trance and Thrash Metal territory.
 * That One Level: This is the End of Your World. It most certainly is. Actually, several of the levels can qualify.
 * In Amplitude: M-80 and I Am Hated, for their incredibly fast strings of repeated notes, and Rockit (2.002 Remix) and Out The Box for their incredibly complex patterns, depending on which portion of the game you're better at.
