Gameplay
Knife Edge is for one to four players. The player, while moving between the locations of the game in the Knife Edge ship, controls a cursor that fires vulcan cannon bullets. When more than one player is playing each cursor is color coded to distinguish them. As well as the regular gun, there is the option for a secondary weapon. Hints are provided by a commanding officer over the communication system.
Movement of the vehicle is clearly predetermined, but the player is given some ability to move in the form of the four C-buttons on the Nintendo 64 controller. When a button is depressed the ship will move slightly in the corresponding direction. This is used primarily to avoid obstacles and attacks.
