This part is where you go to the other police office and go downstairs. Before that, head to the small office and if you see a safe against the wall. Press E to open it.

You'll see a red credit/ID card. Get it (by pressing E). What's that for? You need at least two red cards
 and activate to the computer, which I'll show you later.

 

The door is closed immediately once you get there. Before that, you need to get the plug and connect it to the electricity room. The part where you defend, see the picture down below.

The door will open if you get close and it'll open automatically.

It seems to me the red card is below the small box. Take it.

This one where you defend underground, if you see a computer in the table, turn it on.

If you've pressed E, the monitor will show up some images.

Now, if you hear a 'beep', get back to the corridor where there is a red light in the button.

Press it. Then the green light pops up and the door will open....and...

...somehow you'll see a rocket launcher. Well, sort of. Drop your pistol and get it.

For instance, if you shoot it at the distance. Shoot anywhere by pressing E.

 Boom!!! Let's see if the rocket launcher shot anywhere.

See? It shot so close to me. What a bummer. I thought it can shoot at distances.
I realized the rocket launcher uses once, not many times. I haven't tried out to the zombies how much damage can reduce them.
