Released in November 1995.

This game is an official licensed product of the NHLPA (National Hockey League Players Association). It features the voice of the legendary NHL announcer Pat Foley. Over 100 real players, each player's skill level reflects his real NHL ability. This is the only NHL game that has had the rights to have both of hockey's greatest, Wayne Gretzky & Gordie Howe (hidden player) in the same game.

During the match, you can see in the background an advert for Kellogg's Corn Pops.

The flyer of this game has a photograph of the Chicago Blackhawks goaltender Eddie 'The Eagle' Belfour on it. The text refers to a '140mph' slapshot -- The individual who wrote this seems to have forgotten to do the metric conversion from kilometers per hour. He/she should have written 140 km/h (or 90 mph) as that's more realistic.
