How to unlock the Rocky Road achievement in SSX - Definitive Guide
Choose this event, and make sure you are NOT do not equip armor. Make sure to equip the slowest board you own! You should have a very low survival probability (4%).
Just take your time down the hill. The hardest part is going slow enough during the tight sections with rocks on both sides. It could take a lot of practice and patience, but eventually you will get it. In open areas, take big turns and slow your rider down by pushing back on the left analog. Set yourself up to go straight into the tight spaces and don't focus on losing speed if you can make it through. Make small and controlled movements, jumping earlier, rather than later. See the video for the best route, in my opinion.
Also, you are allowed 3 total rewinds, if you ever take a bad turn, and they will not prevent you from attaining the achievement. You cannot use them once you fail.
Follow the route, equip a slow board, take it easy, don't boost and slow down where space is permitted.
Note: You are free to equip a wingsuit if you think it'll help you.
Complete Deadly Descent: Rocks in the Alps, Mont Blanc - One Way Ticket without equipping armor. If you have not previously completed this event, you will be using Tane. This is a very narrow run and although you can use a wingsuit to soar over a lot of the course with minimal risk, the wingsuit is very hard to control and most of the sides of the canyon will deal damage if you do not have enough accuracy to land on the snow. I recommend equipping a slow board and taking this very slowly, as a staggering amount of this course is able to do damage to you; landing on rocks, hitting a wall, hitting rocks on the course and this will all add up very quickly. The first major jump that Yuri warns you about you cannot take slowly, as there are a lot of rocks directly below the cliff that will do a lot of damage if you land on them. I would recommend maneuvering around rocks when possible as opposed to jumping over them to reduce risk of jumping into walls. Upon completion of this event with no armor the trophy will pop.
