A classic coin-op conversion. Trapping the doors for your friend to walk though was a highlight of my two-player gaming history, replicated only recently with proximity mines in FPSs.
I was playing this awesome game yet on 800XL. Next on ST and still after those all years I enjoy it playing on ST or XL emus. And truly, I have played with lot of opponents but never meet somebody who kick my butt :-)
Somehow I'm finding myself addicted to this game as to IK+ in the age of Tekken 4:-)
