Alter Ego: Keycard and First 2 Fuse Locations

Enter the office and take the stairs on the left. On the top floor, collect the "Lost Book" from the round table at the end.



Go back downstairs and open the bookshelf on the wall opposite the stairs. Take the elevator to the 2nd floor.

Upon arriving at the 2nd-floor lab, go through the decontamination procedure. You only need to do this once to gain free access to the area.

Inside, you’ll find a box for 4 fuses. One is right next to it, so install it immediately. Now, you need to find the remaining three.



With the fuse box behind you, head down the stairs to the right, pick up the Power Core (Battery), and enter the iron door.



The area inside is Test Zone A. There is a security scanner that locks the door if you carry metal through it. 

Toss the battery and fuse over or beside the security gate to the other side.



Behind the fuse station, there's a small lift. 

Go up, grab the small Electric Coil Tower from behind you, and return to the room where you left the battery and fuse.



Clear the body off the chair, place the battery and fuse on it, and plug the Coil Tower into the empty slot.

Step outside and pull the lever in front of the glass to charge the battery and fuse, then take them with you.

Take the fuse out of the box and install it. For the battery, there is a slot on the wall right next to where you originally found it.


Alter Ego: 2 Fuses, Secret, and Cassette Locations

Return to the original battery location, plug it in, and flip the switch on the left to discover a Secret.



Take the small lift behind the fuse room, open the door in front of you, and grab the "Morgue Key" from the desk.

Exit the room and head downstairs via the adjacent steps.



Open the white door to see another door. Instead of opening it, go right, move the metal shelves, and head inside.



Break the painting on the wall and enter to obtain the "Test Site" cassette.



You’ll see stairs on both sides of the small lift. Go left, head to the very end, and you’ll find a fuse on the center desk in the room to your right.


Drop the fuse down first, then locate the lever on the wall. Pull the lever, run outside immediately, and cross the middle bridge to go up.

At the top, you’ll see a passage in the wall. You can’t jump high enough, so use a ladder from your inventory to climb up.


At the end of the passage, you’ll find a Secret and the "Takosi" cassette.


Alter Ego: Final Fuse and Cassette Location

Break the painting inside the holding cell with the cardboard cutout to find the final fuse.



Enter the room labeled "Community." There is a desk in the center; check the lower wall behind it to find the "Machine Taking Care of Itself" cassette.
