Guitar Hero World Tour transforms music gaming by expanding Guitar Hero's signature guitar gameplay into a cooperative band experience that combines advanced wireless instruments with online and offline gameplay modes including online Band Career and 8-player "Battle of the Bands," which allows two full bands to compete head-to-head online. The game features a Music Studio music creator that lets players compose, record, edit and share their own rock n roll anthems.
Note: The instruments are sold separately.
Now back at £20.20 still a great deal though. Price seems to change daily!
