Trials Trophy in Journey
Sneak through the underground passage without tearing your scarf.
How to unlock Trials
While playing the Underground chapter, early on you will encounter a guardian that has a spotlight beam. If it spots you, it will dive at you and viciously rip off a section of your cape. You should run inside the small hiding places, and run from one to the next directly after it passes. It has a very predictable route though, so it is quite easy to sneak past it, just by sticking to the left hand side!
At the end of the level, it is very hard to avoid being noticed (it is possible though). By holding down , you will surf down fast to escape and earn this trophy!
