The Ninja Warriors/Stage 1

Welcome to the game. Once Kunoichi and Ninja have appeared on the screen, start walking to the right as fourteen light-green-uniformed knife-wielding soldiers come running towards you from both sides of the screen; once you've stabbed (or thrown a shuriken at) each of these to kill them for 300 points apiece, two dark-green-uniformed rifle-wielding soldiers will come running towards you from both sides of the screen and fire a shot at you. Once you've crouched down and killed both of these for 400 points apiece, ten more light-green-uniformed soldiers will come running towards you from both sides of the screen - and once you have killed all of these, two more dark-green-uniformed soldiers will come running towards you from both sides of the screen and fire a shot at you. Once you've crouched down and killed both of them, ten more light-green-uniformed soldiers will come running towards you from both sides of the screen; once you've killed all of these, a hunchbacked mutant will drop down to the ground, from the top of the screen. Once you have stabbed him five times (or thrown five shurikens at him) to kill him, for 500 points and five extra shurikens (each hit is also indicated by him hissing from the Yamaha YM-2610), eleven more light-green-uniformed soldiers shall come running towards you from both sides of the screen - and once you kill all of them two more dark-green-uniformed soldiers shall come running towards you from both sides of the screen and fire a shot at you. Once you crouch down and kill both of these, twelve more light-green-uniformed soldiers will come running towards you from both sides of the screen; once you've killed all of them an ochre-uniformed mortar-gun-wielding soldier will come running towards you from the right side of the screen and fire a shot at you. Once you have crouched down and killed him for 400 points, thirteen more light-green-uniformed soldiers shall come running towards you from both sides of the screen - and once you've killed all of these, a seventh dark-green-uniformed soldier and three more light-green-uniformed ones shall come running towards you from the right side of the screen with a dark-green-uniformed non-attacking commander (who is worth 300 points). If you do not kill all five of these enemies quickly enough, the commander will order Retreat! from the Yamaha YM-2610, and any survivors (including the commander himself) will run back off the screen's right side; two more hunchbacked mutants shall then drop down to the ground from the top of the screen. Once you have stabbed both of these five times (or thrown five shurikens at both of them) to kill them (their deaths are also worth a total of ten more extra shurikens), three more light-green-uniformed soldiers shall come running towards you from both sides of the screen - and once you have killed both of these, two more dark-green-uniformed soldiers shall come running towards you from both sides of the screen and fire a shot at you. After you've crouched down and killed both of them, fifteen more light-green-uniformed soldiers will come running towards you from both sides of the screen; once you have killed all of them, two more ochre-uniformed soldiers shall come running towards you from both sides of the screen and fire a shot at you. Once you crouch down and kill both of them, four more light-green-uniformed soldiers will come running towards you from both sides of the screen as an indestructible purple-suited rifle-wielding gangster emerges from an open garage then fires a shot at you before ducking back into the garage again - and once you kill all the light-green-uniformed soldiers, two more dark-green-uniformed soldiers shall come running towards you from both sides of the screen then fire a shot at you. Once you've crouched down and killed both of them, three more light-green-uniformed soldiers will come running towards you from the right side of the screen; once you've killed all of these, a twelfth dark-green-uniformed soldier and two more light-green-uniformed ones will come running towards you from the right side of the screen, with another dark-green-uniformed commander. Again, if you don't kill all four of these enemies quickly enough, the commander will order Retreat! from the Yamaha YM-2610, and any survivors (including the commander himself) will run back off the screen's right side - and six more light-green-uniformed soldiers shall then come running towards you from both sides of the screen. Once you've killed all of them, two attack dogs and two teal-uniformed knife-wielding soldiers will drop down to the ground from the top of the screen; once you've crouched down and killed all of these (the dogs are worth 500 points apiece, while the soldiers are worth 300), three more attack dogs and two more teal-uniformed soldiers will come running towards you from both sides of the screen. Once you've crouched down and killed all of these, seven more attack dogs will come running towards you from both sides of the screen - and once you have crouched down and killed all of them, the stage's boss (who is a black-suited, red-haired, Katana-sword-wielding female ninja) shall appear in front of you. Once you have stabbed her five times (or thrown five shurikens at her) to kill her, for 800 points and five more extra shurikens (every hit is also indicated by her shrieking from the Yamaha YM-2610), Kunoichi and Ninja will walk through the open metal door on the right side of the screen; both players will then receive a bonus of 50 points for every shuriken they have remaining (along with a bonus of 30 points for every fragment of energy they have remaining), and proceed to the second stage.
