The B4F turntable room is an area of the Raccoon City Underground Laboratory that is featured in Resident Evil 2, Resident Evil Outbreak and Resident Evil: The Darkside Chronicles.
When the Ecliptic Express crashed, the room underneath was affected too. The tunnel that the Turntable train would use suffered a cave-in.
After exiting the security room, the player can follow the "MAIN SHAFT" sign on the wall to find the entry to the main shaft. There is also long corridor which leads to the A-2 elevator, but it cannot be access in this scenario.
In scenario A, the player will face five zombies upon returning here at some point.
In scenario B, the player can use the A-2 elevator to enter this area. Upon exiting the elevator, five zombies will be face here. Unlike scenario A, the security room will require the Master Key to unlocked. After the self-destruct system is activated in scenario B for Leon, the player must return here with the Master Key to unlocked the security room to fetch Sherry before heading to the B8F Platform.
