Both riders race the same track (P1 on top, P2 on the bottom). You're light by default - every level is mountains with GAPS between them: launch off a ramp and either drop down to a lower mountain or climb UP to a higher one - flip to match the ground and land! Hold heavier on slopes for speed, but let go before a ramp or you'll roll back and stop. Land a trick for a speed boost (longer air time = bigger boost). Crash and you restart with NEW tricks. All 100 levels are unlocked. Esc = menu.
