Barricade

Hey guys this is my third map post and very first map(with minor tweaks) that I made. It is an infection mapcalled Barricade(obviously). It can be played with basically any infection variant with 4-12 players and there isn't any particular variant for it to be played with.

Backstory

Pvt: Sir, our Hornet is almost out of fuel.
Lt: Very well then. Pilot, land this Hornet on that radio tower there.
pilot: Yes, sir. We are incoming on the radio tower. It seems to be abandoned, sir.
Lt: It's all right, we won't be there for long.
10 minutes after landing
Pvt: Sir, I think I saw something moving. I think something lives here.
Sgt. Don't worry cadet, we're safe here. Nothing can live here because there is nothing to eat and the closest irrigation system would take hours to reach, even by Hornet. There is nothing to worry about.
Lt: Yes, listen to him. He knows what he is talking about. He has been here before.
Pvt: If you say so, sir.
10 minutes later
Lt: Sergeant, where is our squadron?
Sgt: I think they are looking around the station, sir.
Lt: Very well.
A very faint roar
Lt: Sergeant, did you hear that sound?
Sgt: Hear what, sir?
the same roar only a bit closer
Lt: That sound, sergeant.
Sgt: I did this time, sir.
Lt: Scouts! Scope out the premises. I think there is something here.
Pvt: See! I told you, sir.
Lt: Private! What did you see exactly?
Pvt: It looked big, strong, and fast.
Lt: It seems to be a monster.
A loud roar that is near where they are
Lt: Everyone! Get to the top floor and barricade all entrances with what you can find!
Boom!
Lt: What was that?
pilot: I think it was the Hornet, sir.
Lt: Men, hold what you can! Private, call for reinforcements! Everyone else your with me! You three take up the turrets! Everyone else give them covering fire!
Pvt: Sir, the radio lines are down! We have no signal!
Lt: Then God save us.
