While exploring Midtown in Stray, you can find a safe in the store and open it. In the guide, you will find a description of this puzzle - learn the location of the safe, how to open it, and its reward.
Safe location - Midtown level
After reaching Midtown (stage 10), you can start exploring the city part. While walking along the first main street, you have to reach the shop on the right with the client-machine standing in front of it (picture above).
Jump to the counter and then jump inside the store to start exploring it. The safe is on the top shelf in the store (picture above).
The prize inside the safe
There is a Cat Badge in the safe - one of the collectibles. Collecting all badges will reward you with the Badges trophy.
The locations of all collectibles in this category are described on the Badges page in the Secrets and collectibles chapter.
Solving the puzzle with the safe combination
The solution to the puzzle is written on the poster you have to translate, at the back of the store (picture above). It contains a sequence of numbers - 2458.
The only problem is that the code is reversed - the correct one is 8542. Go to the safe and ask B-12 to enter the code.
