Development Hell: Keycard Locations

When the game starts, go through the glass doors and take the stairs on the left to go up.



You will arrive in a room with a large roulette wheel. On the desk nearby, collect the "Access Card" which unlocks the doors on the floor below.


Use the Access Card to open the door and walk to the end of the hallway next to the stairs. Inside, you'll find a door with posters on both sides; enter it to get the "Elevator Access Card."



Take the elevator to the CEO’s office. You will find "Greg’s Key" to the left of the body.


Development Hell: Secrets and Cassette Locations (Part 1)

Once you have the Access Card, return to the starting floor and open the locked door. Move toward the far right.


Before reaching the door at the end, open the door on the opposite wall to discover a Secret and the "To Amore" cassette.


After finding the Secret, enter the opposite door. In the room with a brazier in the center, you will find the "Sword of Darkness" cassette.


Take the elevator up and open the safe in the CEO’s office to obtain the "Beep" cassette.





Head down to the basement and you will see an iron door. Open it, step on the chair and boxes in front of you, and climb over to the right.


Break the wooden planks and head inside. You will find a set of stairs leading further down, where a Secret is hidden.


Go down the stairs to the basement level and check the bed to find the "Lost Opportunity" cassette.


Development Hell: Second Secret Location

After taking the elevator up, you'll find an arcade machine next to the lion statue. Reach the top rank in the "Money Stacking" game to earn a Secret.

The other arcade machines do not provide secrets, so don't waste your time on them.
