As far as I know, you are not infected.
I sincerely hope things do not reach
such a desperate pass, but if it has
turned out that you are now the last
person remaining alive, I want you to
get the material from the Visual Data
Room.

Then, activate the Self-Destruct
System in the Power Room, and escape
from here. Please do everything in your
power to make this whole accident
public.

If everything is still running normally,
you should be able to release all the
locks using the Security System.
