:58:00
What about the T-virus?
:58:01
The T-virus was
a major medical breakthrough...
:58:05
although it clearly also possessed
highly profitable military applications.
:58:11
How does it explain
those things out there?
:58:13
Even in death, the human body
still remains active.
:58:16
Hair and fingernails
continue to grow.
:58:18
New cells are produced...
:58:20
and the brain itself
holds a small electrical charge...
:58:23
that takes months to dissipate.
:58:26
The T-virus
provides a massive jolt...
:58:29
both to cellular growth...
:58:31
and to those trace
electrical impulses.
:58:34
Put quite simply...
:58:36
it reanimates the body.
:58:38
It brings the dead back to life?
:58:41
Not fully.
:58:42
The subjects have
the simplest of motor functions.
:58:46
Perhaps a little memory.
Virtually no intelligence.
:58:50
They are driven by
the basest of impulses...
:58:53
the most basic of needs.
:58:55
Which is?
:58:56
The need to feed.
:59:03
How do you kill them?
:59:05
Severing the top of the spinal column
or massive trauma to the brain...
:59:08
are the most effective methods.
:59:11
You mean shoot them in the head.
:59:14
Why did you kill
everybody down here?
:59:16
The T-virus escaped
into the air conditioning system...
:59:20
and an uncontrolled
pattern of infection began.
:59:23
The virus is protean...
:59:25
changing from liquid to airborne
to blood transmission...
:59:29
depending on its environment.
:59:31
It's almost impossible to kill.
:59:34
I couldn't allow it
to escape from the Hive...
:59:37
so I took steps.
:59:41
- Steps.
- You must understand.
:59:43
Those who become infected,
I can't allow you to leave.
:59:47
Whoa. We're not infected.
:59:49
Just one bite, one scratch
from these creatures is sufficient...
:59:54
and then you become one of them.
:59:59
A check of my systems indicates
my main drive circuit breaker...
