Maintenance Tunnel Warehouse

 is a room in the Maintenance Tunnels in Dead Rising. The Maintenance Tunnel Key is found here. The end of Case 7-2: Bomb Collector takes place in this large room. Brad Garrison dies just outside of this room.

Maintenance Tunnel Key
The Maintenance Tunnel Key is found in the far corner behind some boxes. The key opens all of the maintenance tunnel doors throughout Willamette Parkview Mall. It is indispensable later in the game, especially in Overtime Mode.
