<P> Fortnite uses procedural generation to build out the maps for each mission . The game also includes an "AI director" that monitors how players are progressing, and alters the challenges of the monsters it sends out to the players based on that progression, easing off if players are having greater difficulty in surviving . At one point, the game had a team - based player versus player mode, where each side attempted to build up a base around a central target while trying to attack the opponent's target after breaking through their base . This did not make it into the final game . </P> <P> Epic currently has cross-platform play between PC and PS4 and has stated plans to allow separate Fortnite cross-platform support for Xbox One and personal computer users, but cross-platform play between all three platforms has not been announced . However, for a few hours during one day in September 2017, players found they could cross-play between all three platforms . Epic later corrected this, calling it a "configuration error". </P> <P> On July 26, 2017, it was announced that Fortnite had sold over 500,000 digital pre-order copies . On August 18, 2017, Epic confirmed that Fortnite had surpassed over a million players . </P> <P> Eurogamer ranked the game 32nd on their list of the "Top 50 Games of 2017". It was also nominated for "Best Co-op Game" in PC Gamer's 2017 Game of the Year Awards, and for "Best Spectator Game" in IGN's Best of 2017 Awards . </P>
