In Crime Scene Cleaner, you play as a janitor hired by the mob to clean up their dirty work. This guide covers how to unlock the Rock and Roll All Nite achievement/trophy.
In Mission #5, The Italian Job, there’s a well-hidden secret area called the Rowbau concert venue. To find it, enter the restaurant and head through the second door on the left. This leads to the office. From there, go out the back door into the alley. As soon as you step outside, look to your immediate left.
To get over the wall, you’ll need a step ladder. If you haven’t unlocked this item in your skill tree yet, don’t worry. There’s one available right in the back alley. Grab it and place it on top of the pallet by the wall to give yourself enough height to climb over.
Get yourself up and over the wall and you’ll find the Rowbau concert venue and earn yourself the Rock and Roll All Nite achievement/trophy. While you’re in this area feel free to strum the guitar up there as that is tied to another achievement/trophy for playing some guitars.
