Hysteria

A fanatical sect has changed mankind's future by summoning a previously extinct primeval entity in our past. You, a sole survivor of the once elite 'time corps' have been chosen by the federation of law and order to combat the entity in three time zones: Ancient Greece, Dark Ages and Space.

The game, controlled by joystick, has you moving the time warrior in horizontal-scrolling parallax levels. You have to collect nine pieces that assemble to a face of the primeval entity who must be battled.
