How to find Easter Egg music cassettes on Firebase Z
Below is a step-by-step guide to finding each of the three cassette tapes needed to unlock Easter music.
Cassette Tape One
To start, you’ll find the first cassette in the Village area.
This tape is located on the second floor, just above the Pack-a-Punch area, in the Scientists’ Quarter. The tape can be found on a shelf not far from the stairs.
Cassette tape two
Located across the yard, you will find the second cassette tape inside the equipment storage room. You will find the cassette tape on the shelf that is located next to the cabinet you open to get the serum during the main Firebase Z Easter egg.
Cassette tape three
The third and last cassette can be found after using the teleporter.This particular cassette is quite complicated to find, as when exploring the right corner of the Motor Pool Office you will find the ribbon on the floor between a cream colored table and a green file.
After collecting all three cassette tapes, the Easter Egg song will start playing automatically.
