How to Find the Easter Egg Song Cassette Tapes in Firebase Z
Listed below is a step-by-step guide for finding each of the three Cassette Tapes that are needed to unlock the Easter Song.
Cassette Tape One
To start things off, you will find the first Cassette Tape in the Village area.
This tape is located on the second floor, right above the Pack-a-Punch area, in the Scientist Quarters. The tape can be found sitting on a bookshelf not too far from the staircase.
Cassette Tape Two
Located across the Courtyard, you will find the second Cassette Tape inside the Equipment Storage room. You will find the Cassette Tape on the bookshelf that’s located directly next to the locker that you open to obtain the serum during the main Firebase Z Easter Egg.
Cassette Tape Three
The third and final Cassette Tape can be found after using the teleporter.This particular Cassette is rather tricky to find, as upon exploring the right corner of the Motor Pool Office you will find the tape on the floor between a cream colored desk and a green filing cabinet.
Once you have collected all three Cassette Tapes, the Easter Egg song will begin playing automatically.
