|A True Descender|
Finish a session from highlands to peaks
One of the more challenging achievements in this game, but perfectly doable. Start from Highlands and work your way all the way through to the Peaks, in order to unlock gold-and-silver patterned equipment for your biker.
The key trick is to simply amass as many lives as you can from all the bonus objectives, in order to give yourself more leeway and a higher room for error. These lives will be especially useful on the boss jumps (although the Highlands and Forest boss jumps are skippable) and in the Peaks areas, which are the problematic spots.
