Red Series 1-5 addon - Duke Nukem 3D

"Duke to headquarters! Does anyone hear me? We have a code RED! I repeat: we have a code
RED!!! Hello???"
The only answer from the little machine is some creaking noise.
Useless. No one hears you. No one knows about the situation you're in at the moment....
Desperately you throw your speaker to the ground. Behind you something tries to slam the door
with devastating force. Again. Luckily you barricaded it well enough to keep any of those...
things out. You're save, for now. You look out of the window. The sky turns red as evening
begins to fall. You see the shadows of those monstrous creatures moving all around the building.
You're trapped.
How did it come this far?

Things started when the EDF-satelites picked up some unusual movements around Mars.
After the previous invasion of a bloodthirsty alien race, the one you stopped almost
single-handedly, EDF decided that such an event should never occur again. They set up
a huge headquarters in the heart of Los Angeles. From here, all EDF-actions are controlled.
Satelites were aimed at space, scanning the universe in search of the home-planet of this
agressive alien civilisation. Meanwhile, they also monitored the more nearby parts of
outer-space, such as the moonbase. Earth itself was also closely monitored. Reports of
UFO-sightings or strange events all were well documented and analysed. If anything unusual
would happen, or some alien fleet would be heading this way, EDF would know about it.
And they would be prepared. The HQ also was home of an gigantic, professional army, an army that
was practically invincible. In case of a "code RED", this force would make short work
of any dangerous enemy force.
Thanks to this, the unusual activities around Mars didn't go by unnoticed by the EDF. There
seemed to be some strange fleet gathering, orbiting Mars. Strangely enough, nothing else
happened. The monitoring of this strange fleet became the most important operation of the
EDF. What was the plan behind this? Was it a hostile fleet? Should we send in our troops?
Any attempt to communicate failed, but the fleet seemed to be getting bigger and bigger.

Maybe it's because of this that the increasing reports about strange phenomenons on Earth
were ignored..

Meanwhile on Earth, other, seemingly less important events occured. Some hacker,
calling himself "Invader" declared in some audio file that was spreading around the
internet that he would hack into the EDF-systems as an ultimate showcase of his skills.
No one knew who this guy was so everyone assumed this was just some kind of hoax.
Until some of the satelites that were pointed at earth suddenly began to malfunction.
Something else was controlling them.
In a threatening situation like this, the EDF couldn't affort any of this things.
It was highly urgent to stop this hacker. So you were called to headquarters.

"Listen up, Duke", the chief in command said "this Invader-guy should be stopped immidiately,
if we loose our satelites God knows what that mysterious martian fleet will do, without
us monitoring them"
"Maybe that's his.. or its intention?" you replied, "maybe the motives of Invader are not
what they seem to be. I think these 2 cases are connected"
"Yes, we also tought of that, and it seems to be very likely. You see how urgent it is
to track this guy. The problem is, with him controlling our satelites this won't be easy.
We have the biggest force in the universe, but even that force is useless if we don't know
what the danger is and where it's hiding"
"Very touching sir."
"Tell me about it. Anyway, we have a good idea about his hiding spot. You see, there's
another strange thing happening. A huge area between L.A and Las Vegas seems to be cut
off from the rest of the world."
"How is that even possible?", you asked sceptically.
"We have NO idea. All communications with this area are down, it's like the place has
been erased, like some forcefield is shutting it out from the rest of the world.
We think it's Invader who did this. He probably hides somewhere within that area and
tries to erase any tracks leading to him. And I must say, it will be very hard to find
him, IF he's there in the first place." Your superior paused for a moment.
"We can't afford to send in any troops, we can't be sure about his position. Besides
the troops must be ready for any sudden code red. We don't know what that fleet is up to.
But IF he's in that area, he'll probably use the abandoned Lonely-mountain facility as
a hiding spot. It would be the ideal place."
"So that's why you called me?"
"Exactly. We want you to head to that facility and see if our hunch is right. Remember, all
of this has to happen in stealth, no-one but us should know about it!"

You thought this would be an easy job: get there, search the area and report back.
But you know better now. Once you finally reached the long, deserted wastelands, the steep
cliffs and the wild mountain areas, the radio in your car just stopped working.
After checking your cellphone and your laptop, you found out that any try to communicate
with Los Angeles was futile.
The chief was right.
Something was cutting this area off from the rest of civilisation.
As you drove deeper into the heart of the area, you got more and more nervous.
Something felt terribly wrong. The whole area seemed to be deserted. No other cars were on
the road, houses appeared to be empty. Sometimes you could vagualy hear some weird
shrieks in the distance, and weird little earthquakes shook the ground every once in a while.
Something was watching you. You could feel it.

It must have been somewhere late in the afternoon when your car suddenly just broke
down. When you checked the engine you couldn't find anything wrong with it. But something
was very wrong. You felt it. Nervously, you looked around you. Your surroundings where
mainly filled with sharp, steep rocks. Not too far ahead, you saw a small bookshop
standing on top of a hill. The wind was moaning, no other sound was heard.
With the idea some people in there could help you, you walked towards the shop.
Slowly you opened the door. Nothing. No one. The place was completely deserted.
This was weird, this couldn't be just becouse some mere hacker. Something else was
going on...
Before you could think futher about this, you suddenly heard a tremendous
explosion. Turning around, you saw the burning wreckage of your car.
Before you could even react to this, an ear splitting cry pierced the sky.
And suddenly, you could see them. The hidious faces of Pig cops coming from every
direction, pointing their shotguns at you, ready to fire...

And now you sit here. Unable to reach HQ, trapped inside the building, surrounded by pigcops.
Luckily you could barricade the door in time, but it wouldn't take long before they would
find another way in. You grab your pistol. It won't be enough to stop all of them....
What the hell is going on? How could this place be crawling with
aliens? What is the connection with Invader or the mysterious fleet?
You see only one option: continue your way to you original goal and hope you can send a
warning message to Los Angeles from that point and find out what the hell is going on.
If you can escape from this hellhole in the first place...
