Rugby League 2 is the sequel to the highly successful NRL Rugby League, and was released on December 9, 2005 for PlayStation 2 and Microsoft Windows, and in June 2006 for Xbox. The sport is similar to rugby union, but features set tackles rather than rucks and mauls - once a player is successfully tackled he plays the ball back to a team-mate behind him, with the team losing possession if tackled 6 times.
