The main new feature of the game other than the motion capture was the indoor football mode. There were six ways to play the game, including outdoor and indoor, as well as action and simulaton modes. 32-bit AI was used, as well as motion blending technology which led to some of the sharpest graphics in any football game of the time. Here, it was possible to play six-a-side football in an indoor arena with the ball bouncing off the walls meaning there is no throw-ins and therefore a much higher paced game. Leagues available in the game included the English, French, Italian, German, Dutch, Scottish leagues and the Malaysian M-league and other sides, as well as the American A-League clubs with fictional teams, composed of the game's creators such as Bruce McMillan and Penny Lee. Commentary is provided by John Motson and Andy Gray while the presenter is Des Lynam. Multiplayer games are also possible with up to 20-players via. LAN and 8-players using modem. The game trailer's tagline was "FIFA 97, it will blow you away." Most European domestic leagues were featured in the game, including the English Premier League, but only teams from each nation's highest division were playable. The English clubs featured in the game were those who played in the 1995-96 Premier League. It was also possible to field custom teams made up of players from various real teams. However,these teams could only be played with in friendly matches.
