When the elevator reaches the lower levels, M-21 cuts the door open and the three of them enter the base. Upon seeing the door of the base closed, M-21 is surprised and claims that the door isn't for locking an enemy inside but rather for preventing the researchers from escaping. He further tells Raizel and Frankenstein that the door can only be opened from the outside and is useful for creating a complete lockout. They open the door and are surprised to find an area that should be heavily guarded without any security. Even in the Control Room, all connections from the cameras were lost, leading M-21 to comment that some suspicious is happening in the base. Frankenstein suggests that they should go to the lab now that they have come this far.
While going down even further, M-21 states that a lock-down must've been ordered and it must've happened recently. They exit the elevator only to find out blood splattered all over the ground in the entire corridor. Suddenly there are shots fired at them, which M-21 dodges and Frankenstein easily stops ones going towards Rai. The one shooting was Lt. Simon, who asks why M-21 came back after all that happened and then tells him that it was Dr. Crombel who betrayed them all.
Simon tells M-21 that Crombel used both the researchers and later his troops to obtain all the data on a new specimen and then left in his helicopter. Frankenstein leaves to find Crombel after taking permission from Rai. M-21 tells Rai that there are no possible survivors and Crombel, whom they wanted to meet is gone, thus there is no reason for them to stay. Rai reminds him that he came there to do something else and tells him to lead the way. Crombel comments from his helicopter that there was not enough data as Lt. Simon's men were easily killed. As soon as he sees M-21 in the camera footage, he gets excited and tells the pilot to return to the base.
