it may be old, but its still worth playing!!!
Graphics: well what can i say, there great, end of story.
Gameplay: this is where its lacking a tiny bit, its an arcade game, walk, kill all enimies, move on, the standard thing, but it is still good.
Sound: this is where this game shines, the sound and music is outstanding! u could buy this game just for the music its that good! definately its strongest point.
grafhics: its an nes, its great! a little retro now but back then, awsome!
dificulty: another good thing aboot this game, its a little harder than other games, but after u play it, youll realize that if it was easier, it wouldnt be as fun, so its good in this field too.
over all, if u find this game in a bargain bin somewhere, then u should definately pic it up!
