Guitar Hero fans aching for some companionship with their game can now rip some chords with a friend, thanks to the game’s custom controller now being sold as a stand-alone product, rather than solely with purchase of the Guitar Hero software.The Guitar Hero SG controllers are modelled after the Gibson SG and are identical to the controllers shipped with the full version of Guitar Hero, so the "I have a different type of controller" excuse won’t cut it when you’re doing poorly while playing with a friend."Guitar Hero is a staggering single-player game made even better in multi-player mode," says Kelly Sumner, CEO, RedOctane. "We’re delighted to now be able to offer a limited number of standalone guitars in-store for those keen to settle musical scores."In the game’s multiplayer mode, players take turns playing sections of songs where players are judged on accuracy, timing and "judicious use of Star Power." Yes, that’s an actual quote from the press release.Guitar Hero was a succesful music game that aided in making players feel they have actual musical talent, thanks to the game’s guitar-like controller. Guitar Hero 2, which should feature even more songs for players, is expected to ship later this year.
