How to unlock the Green wave achievement in Gravel - Definitive Guide
If you struggle to get this, just slow down. Hit the green arrow signs and NOT the red X signs.
A Smash-Up race is a race event with signs on the track that randomly show green arrows or red crosses. During the playthrough of your career (Off-Road Masters) you’ll have to play through many of these events so chances are that you’ll get this without going out of your way for it. If you didn’t get this during your career however, just retry one of these events and take it as slow as you need to. Remember the trophy only requires you to complete the race while hitting only green signs, so you don’t have to actually be fast and win it.
