will not be an easy task. You must kill them by means of

with bombs, you must work your way through each stage, killing
all that is moving other than yourself. As I remember, there are
50 levels. Each stage you will find some sort of bonus. It may be
the ability to hold more bombs, bigger explosions, the ability to
walk through walls, or a few other things. It is an entertaining

Bomberman was made by Hudson Soft. Bomberman became popular enough for them to make a second one for the NES and several other systems including SNES and N64. This game is definitely worth getting if the price is right. This game will run you a little more than most common NES games. At most game stores it is around $15 with no box, but Funcoland would probably be the best deal. I am not sure about that though.
