OMG! Speaking of Robo Warrior, I got one of those old NES Game tips videos, there's a walkthru of Robo Warrior from beginning to end, with a man's voice narrating the whole thing. Unfortunately it's been edited, they had to cut out portions of the video to save time.
IIRC you really have to depend on luck to get through this game, I only reached the final stage once but that was in the mid 1990's. Getting bombs is hard enough as
>using them all up on one screen and watching your player's life gradually fade,
>getting wound up in a boss battle with no bombs.
>Or trying to find your way out of the dark tunnel when you have no candles as you can't see the exit and what power ups you picked up!
But in the end that's what made it a fun game altogether.
