Original missions, not a film plot, structure James Bond 007: Agent Under Fire, EA's 2001 Bond game. The GameCube version adds split-screen multiplayer the PlayStation 2 release lacked, so a second pad on the cube is a mode the earlier disc did not have.
Q's gadgets and a driving section still frame the solo missions. The multiplayer maps are the cube-specific reason to care which Bond disc is in the tray.
EA's original mission set is the campaign on every platform. The split-screen is the cube's addition, and the PlayStation 2 game simply does not have it.
