The RedOctane X-Plorer Controller was a controller created by Activision and RedOctane released in bundles with Guitar Hero II for the Xbox 360, some bundles of Guitar Hero III: Legends of Rock, or available separately.
This same controller was also bundled with Guitar Hero III: Legends of Rock for the personal computer (PC) and Macintosh.
The Xbox 360 controller works with the PC using a driver with Windows (XP SP2 or Vista only).
The RedOctane X-Plorer Controller for these games is based on the Gibson Explorer, a type of electric guitar.
It is also the only guitar controller officially supported by Aspyr Media (developer of the PC and Macintosh releases).
