Finest Hour (Japan) — About this game
Finest Hour (Japan) gives Sygnus a heat gauge instead of a conventional life bar. Damage raises the temperature and undisturbed movement allows cooling, but exceeding the time limit breaks the cooling system. The robot’s Vernier jump-jets need recovery after landing, and it cannot reverse its facing in mid-air. A marker selects the laser’s automatic target, while a double directional press changes the ground march into a dash.
