Appearance in the games
Fire Field first appeared as the last and hardest track in the original F-Zero. It features dangerous turns and a fork in the road near the end.
In F-Zero X, Fire Field is the first track of the King Cup, it's easier than in the original, but has a zigzag jump and a sharp ascent. Fire Field 2 in the EXpansion Kit, has a 180 degree rollover as well as a cylinder that can throw you off at the end of it.
In F-Zero GX, Cylinder Knot is a simple cylinder course and Undulation lacks guard rails in many places and bumpy roads, making it very dangerous.
In F-Zero: Maximum Velocity, Fire Field appears as the final two tracks of the game, Land Mine Circuit, and Warrior Circuit. Land Mine Circuit, as the name of the track states, it a circuit with a barrage of mines, it also has lava, and has wide areas to dodge the mines. Warrior Circuit is also contains mines, however it is filled with many turns and more obstacles.
In F-Zero: GP Legend it appears again as the fith track for the Bronze Cup (Blast Track), and the fourth track (Wreckage Circuit) in the Gold Cup. Blast Track is a simple oval but is riddled with bombs and lava at the edges, and is used as an obstacle to avoid. Wreckage Circuit is a simple track but the turns are circular with bombs around.
In F-Zero Climax, two tracks and it's Expert and Master variations appear. Heat Circuit is a simple track with turns and lava, while it's variation Burnt-Out Rink, includes explosives and a few more turns on the track. Front Line 1 (and 2) is a track decked with Lava, and Explosives.
Also, the SNES F-Zero Fire Field appears in both GP Legend and Climax as the final track in the Platinum Cup, nearly unchanged. Fire Field is the only course to appear in every F-Zero game.
