The goal is to escape the destroyed city, finding safe paths through collapsing buildings and dealing with panicked and fleeing people.[3]
The game was to feature over 60 characters, the largest in series history. The player would have had to work with these people to escape.[3]
There are a few new features Irem highlights for Disaster Report 4:
The player can enter collapsed buildings, within which the player will find survivors and additional escape routes.
The game has a new "cleanliness" parameter for the character. If the character gets too dirty, stress will rise.
The player can use the toilet to increase the main character's cleanliness parameter.
The player is free to customize the main character. At the start of the game, the player can set the main character's gender, face style, and hair style. Over 100 clothing items, including suits and casual outfits can be earned as the player works through the game.[3]
