An abbreviation of Over Zenith, perhaps to avoid legal action from the owners to the rights to the Wizard of Oz from which this game takes its character traits. In hot pursuit of Dorothys kidnappers, players fight full 3D battles to progress alongside two companions. Teamwork leads to foes getting a good beating and socked up into the air, where the next team member adds their attacks and so on to the next guy. It also builds up the meter which allows super attacks to be utilized. And some bosses are only susceptible to these super attacks. Plenty of Konami's high class production values on show.
