How to Get the ‘Grunge Metal’ Trophy/ Achievement in Mixtape

While Mixtape’s gameplay is pretty straightforward, there are some achievements or trophies that you can easily miss. Some of them are pretty self-explanatory. The ‘Grunge Metal’ achievement is a bit of a mix. While the premise of making Slater’s secret slushy recipe is simple enough, at no point in the game are the components of his slushy recipe clearly stated. However, after a bit of trial and error and a few playthroughs of this section, I uncovered exactly what Slater’s secret slushy recipe is in Mixtape, so you can unlock the ‘Grunge Metal Alchemist’ trophy/ achievement on your first playthrough.
