I never played Zaxxon before so I pretty much died instantly. How do I play?
It's isometric with not just left right front and backward, but also up and down.
It's indeed kinda confusing with newest graphic
Too many things on the background
so better be used with its prequel first with simple graphic.
I suggest trying the SG-1000 version first.
