How to Get the 'Grunge Metal' Trophy/Achievement in Mixtape

A guide shows how to unlock Mixtape’s hidden Grunge Metal/Grunge Metal Alchemist achievement in Chapter 8.

The recipe is Slater’s secret slushy: combine Blue Crush, Bubblegum, Orange, and Lime in any order.

Players can find the recipe earlier in Slater’s House, making the trophy easy to miss on a first run.

The guide helps players grab the achievement without relying on chapter select or a replay.
