Big Mountain 2000

Big Mountain 2000, known in Japan as Snow Speeder (スノースピーダー, Sunō Supīdā), is a skiing/snowboarding video game for the Nintendo 64.

Big Mountain 2000 puts the player in control of one of six racers of varying abilities using either snowboard or skis.

On top of trying to beat their own personal record, the player also has a countdown timer which will disqualify them from the race if it reaches zero.

After completing all race types using skis and snowboards in each of the four stages, a mirror mode Championship is unlocked.

Upon completion of all 24 races again in the mirror mode, three bonus characters are unlocked (which are alluded to in the game's instruction manual).
