Anyone that has played this somewhat unknown space shooter on NES? I bought my copy around 1987 and always enjoyed it. The game plays kind of like a Xevious clone, only much better. For replay value, Zanac has randomness of the enemy ships built in. No two games play the same. Only gripe I have about Zanac is that playing it on the standard NES controller is fatiguing to the thumb. Playing it with NES Advantage stick is the way to go with this awesome space shooter.
