Ninja Gaiden (NES) - Act IV
1After the death of Walter Smith, Ryu is introduced to some secret agents from an organizations known as the Central Intelligence Agency (CIA). The head of the trio is Foster of the Special Auxiliary unit. Foster explains that Walter has sealed off the Amazon ruins until an evil source took over in the present day. After a lengthy conversation, Ryu travels to the site of the Amazon in an effort to investigate the main source. At the start, jump over a river of toxic water and take out a few gunners. Some spots may have dogs and eagles flying, so be on alert for that as well. You may also witness some bats and burglars at some spots ahead as well. Climb a ladder to higher ground and you’ll meet the same species you encountered at the start of the stage. At the cliff, there seems to be a mysterious mountain. The next area has abandoned mine carts on the track. Some spots have jumping ninjas, so be sure to keep your guard up. Skeletal swordsmen throw swords, so dodge them while you can. Climb the next ladder at the end and you’ll enter the interior of the mysterious fortress. Boxers and club users are in the area. Climb another ladder and you’ll see some spin kickers along with reptile cannons. Defeat an axe thrower and climb another ladder. Continue ahead and you’ll battle against 2 Kelbeross statues. These statues will bounce around and shoot acid bubbles. Defeat them both and someone will demand to hand over the demon statue. The girl that was first met at the bar has been held hostage by the demon’s henchmen. With no choice, Ryu puts down the statue and falls into a trap.
