Coming off the failure of the previous Bond game, Tomorrow Never Dies, it was decided that The World Is Not Enough would go back to its roots as a first-person shooter, popularized by the success of the Bond game GoldenEye 007. In the Nintendo 64 version, it would also see the reintroduction of the multiplayer portion of the game that gave GoldenEye 007 such a lasting appeal. The Nintendo 64 version supports the Rumble Pak controller accessory, as well as the Expansion Pak, with which the resolution of the game's graphics is enhanced. It features 14 single-player levels, as well as multiplayer mode with 4-player support and AI bots. As with GoldenEye 007, the in-game weapons are based on actual weapons, but with the names changed. For example, Bond's sidearm, called "Wolfram P2K" in-game, is based on the Walther P99. This was the first 1st-person James Bond game wherein the player could switch the 'mode' in which a weapon operated, such as mounting or removing a silencer or switching from single-shot to full auto, although silenced pistols had appeared in GoldenEye as separate weapons.
