Nope. The demo group was a hungarian team called Impulse, and you can get info about this product in the demo Voyage in Storm or Muscles, just check the endpart scroll.I can´t remember exactlyin which of this two. It had a Mike Oldfield theme "modulized" beneath it.
I wonder why nobody mentions Capital Punishment in the line of all time best beat´em-ups´list? It has buggy code somehow, but not worse than Fightin´Spirit, which randomly freezed on my A1200 way back the time when it was released.
