Four CD's in this bumper collection with the dramatic arcade versions of Raiden, Raiden II and Raiden DX making up the first disk. The PSX version of DX accompanies the sick beats of the arcade version of Raiden III on the second disk. The 360 and arcade versions of Raiden IV make for an all-action. All-guns-blazing disk three. The final disk contains the Insanity DVD musical versions of Raiden IV. Long live Kaihatsu.
