Rock Band 3 Xbox 360 Game

Rock Band 3 is a music video game, developed by Harmonix Music Systems. The game was initially published and distributed by MTV Games and Electronic Arts, respectively, with Mad Catz taking over both roles a year later. It is the third main game in the Rock Band series. As with the previous titles, Rock Band 3 allows players to simulate the playing of rock music and many other subgenres using special instrument controllers mimicking lead and bass guitar, drums, and vocals. Rock Band 3 expands upon previous games by including three-part vocal harmonies—previously used in The Beatles: Rock Band and Green Day: Rock Band—and support for a keyboard instrument, a MIDI-compatible 25-key unit.
Rock Band 3 features a new "Pro" mode, which is designed as a learning tool to accurately mimic playing of real instruments. In Pro mode, guitar and bass players have to match specific fingering on frets and strings, drummers have to strike cymbal pads in addition to snare and toms, and keyboardists have to use precise fingering across the whole keyboard. MadCatz and Fender are manufacturing controllers and add-ons to support Pro mode.
Prior to a song, each band member selects from one of four difficulty levels, Easy, Medium, Hard, and Expert, which influence the number and rate that notes appear on the note track; they also can select the Pro mode for guitar, bass, keyboards, and drums. As the band performs, they score points. Each player can build up a multiplier by hitting consecutive notes correctly, which increases how many points each note is worth, but the multiplier is set back to 1× if a note is missed. After successfully completing a song, the performance of each player and the band as a whole is rated on a 5-star scale. The best performance by a player for each song in the player's library is tracked separately based on instrument, Pro mode, and difficulty, and is used to provide and compare leaderboard statistics.

This game is also available on Wii, PS3 and DS.
