Ninja Gaiden NES

[Jordiway]

There is a way to build up your weapon points at the very end of the game when you go up to the very last level you can keep going back down and collecting the points just make sure you die on the top level keep doing this until its full so when you face the final boss you have all your weapon points i am pretty sure everytime you use a weapon it costs 5 points and for the first 2 bosses you need the weapon that shoots up in the air and you need the big stars for the final boss
