The Waverider re-entry vehicle, based on the Blue Streak missile, was devised by Professor Terence Nonweiler of Queen's University Belfast, and was intended to be the manned spacecraft in the British space programme.
The game is a vertically scrolling shooter with a "virus infiltration" theme: the player plays the role of the Waverider computer virus, and the enemies he or she encounters are Con-Human's antibodies, programmed to terminate any virus—including the player—getting inside the supercomputer's system.
The timestream was mainly used by Waverider during Armageddon 2001, Death of Superman, and Zero Hour events.
