There's something different in the air today. An...electricity. It surges through you and your off-road machine. The mud and hills are calling. You've spent hours in the garage and the track preparing for this moment. All eyes are on you!
Live head to head racing isn't for the weak, but you're no wilting daisy.
Can you even compete? Can you win? Your fate is in the mud, the rocks, and the mountains now.
