Mixtape에서 슬레이터의 비밀 슬러시 만드는 방법

Find Slater's hidden slushy recipe and earn the Grunge Metal Alchemist Gold Trophy in Mixtape with this step-by-step guide.

Mixtape by Beethoven & Dinosaur is a coming-of-age narrative about three teen friends spending one last day together before their lives pull them apart. Buried inside its story is a deceptively tricky trophy tied to a slushy machine, a hidden recipe, and a bedroom wall you might walk right past. The Grunge Metal Alchemist trophy sounds like it should be hard to miss, but the game deliberately separates the recipe from the moment you need it. Here's exactly how to track it down and cash in that Gold Trophy.

The recipe is not at the convenience store where you first make slushies. That's the trap. The recipe sits on a wall inside Slater's bedroom, which you access during the story chapter called "Slater's House." The visit to his room is a compulsory part of the narrative, so you will reach it naturally.

Once you're inside his room, head north toward the wall on the left side, near the bedroom window. Interact with the prompt there, then look down and to the right. You'll spot a poster listing the four flavors that make up the legendary recipe:

Write those down, because the game won't remind you of them when you need them.

The slushy minigame takes place in the "Ultimate Slushie" chapter, which comes before you ever visit Slater's room. That timing mismatch is exactly why so many players miss this trophy on their first run. Once you've seen the recipe, here's the process to get the trophy:

You can complete this with either Rockford or Stacey as your active character. The trophy triggers regardless of which protagonist you're playing.

Completing the correct recipe awards a Gold Trophy (or the equivalent achievement on PC and Xbox) for the Grunge Metal Alchemist condition. Beyond the trophy, the game also delivers a special line of dialogue when you nail the recipe. If you want to hear every possible reaction, it's worth experimenting with other flavor combinations too, since the duo's improvised names for wrong combinations have their own charm.

Mixtape launched on May 7, 2026 on PS5, Xbox Series X|S, and PC, developed by Beethoven & Dinosaur and published by Annapurna Interactive. OpenCritic currently shows a Top Critic Average of 94/100 with 100% of critics recommending it.

Technically, no. Because Mixtape includes Chapter Select, you can return to the "Ultimate Slushie" chapter at any point after visiting Slater's room. The trophy is not locked to a single playthrough window. That said, it's easy to overlook the recipe poster entirely if you're moving through Slater's room quickly, so knowing where to look saves a second trip.

For players chasing the full list of 27 trophies, this one is among the trickier pickups simply because the recipe and the minigame live in separate chapters. Check out the Mixtape trophy and achievement guide for a full breakdown of every award in the game, including which ones are story-unmissable and which require specific actions like this one.

Mixtape sits firmly in the adventure games space, and its hidden details reward players who take time to explore every corner of each environment. Slater's bedroom is a good example of how the game hides meaningful content in plain sight. For more tips across the full game, the Mixtape strategy guides collection has you covered.
