All modifications have been made on level -2:
The sound of the door leading to the main warehouse has been improved (previously it sounded on the left, now on the right, which is the direction it turns).
A radio broadcast has been added in the main warehouse radio, where the announcer talks about the national emergency situation and the bunker where the player is located.
Interaction has been added to the note on the table in the abandoned house so that the player can pick it up and read it comfortably.
Elements have been added to the checkpoint when exiting the elevator.
