This is nothting more than a fan-fic that I am doing just for fun. Any names connecting to reality are a coincidence. Also any similarities to other Half-Life fan-fictions are also purely coincidental, so please don't gripe about stealing ideas.

Half-Life: Mercy is Not an Option

Prologue: Reinforcements

Location: Black Mesa, somewhere in Southwest U.S. Time: 0900 hours. Any passer-by would note that a black dot was moving in the horizon. One who would be any closer would see the dot was a green military helicopter. Anyone closer would be shot, due to seeing too much. The mission was to be completely secret: no information would leak into the public. Utter chaos would flow across the globe if anyone knew of the Black Mesa incident.

These words had been repeated to private Dylan Henderson and all the other marines on the helicopter. Henderson sighed at the words: such secrecy would only mean that this would be history's most dangerous military mission. No further information would be given been given until 20 miles from the target: the Black Mesa compound.

"Hey, Dylan!" a fellow marine called. Henderson turned to look at private Greshwald, his companion from boot-camp. "I heard that this is such a dangerous mission that the assassins were called!" Greshwald said, and Dylan couldn't help but smile back. "You don't seem that scared," he answered.

"Scared? You kidding me? Ever since becoming a marine I ain't got any piece of the action!" Greshwald piped like an excited puppy. "Don't you wanna take on some terrorists and such?" he asked Dylan. He wasn't so sure. Ever since his brother had been stabbed through the heart with a switchblade, Dylan couldn't stand fighting. Dylan's brother had been dealing cocaine when an angry client decided to pay him back. For this reason Dylan joined the army, so he could always be ready if a situation like that came up.

"I dunno," Dylan finally said, "this can be our only battle that we see, we could get killed." "Bah!" Greshwald exclaimed. "Every mission has that danger! Right guys?" he asked the other marines. They all nodded and then returned to playing cards with each other.

Then lieutenant Manners stepped in from the cockpit. The marines rose up to salute their fearless leader. "At ease, men," Manners said and the marines sat back down. "All right, men, it's time for mission briefing." When Manners added this, the marines all got excited. Everyone in the group was a newbie, and they were all at least a bit hoping for a fight.

Manners pulled a small projector from the cockpit and set it up. The picture was unfortunately small in the cramped helicopter. The two ospreys had been sent an hour ago to Black Mesa, so all reinforcements had to travel in the Apaches. The picture on the wall was of the main building and it's nearby compounds.

"As you know, an hour ago main troops were dispatched to deal with a terrorist problem. But what I am about to tell you is not to be told anywhere outside Black Mesa. The grim secret must remain that: a secret." The marines fell silent. This didn't sound good. The projector switched to show a yellowish crystal.

"Does anyone know what gem this is?" the lieutenant asked. Unlike most leaders, Manners tried to be nice to his men when not in battle. A hand rose. "Yes, private Erwin?" Manners asked. "It's a topaz, SIR! And might I mention a rather large one, SIR!" private Erwin exclaimed. "WRONG!" Manners said. Dylan had a surprised look on his face: he didn't know of any other gem like that which wasn't a topaz. "There is no substance like this on the face of the Earth!" Manners' words caused everyone to gasp.

"That's right! The 'terrorists' are actually something not from this planet, maybe not from this solar system!" Another gasp shook the room. The projector now showed a huge reactor sending down beams onto the alien rock.

"This machine was meant to be used for creating a portal inside Black Mesa to code name X-599, a planet somewhere far away. The experiment resulted in the mass teleportation of extra-terrestrial beings into the compound." Manners sighed. The projector switched to show the team of scientists and guards of Black Mesa.

"Our team was sent with two objectives: 1. Destroy alien personnel. 2. Destroy the Black Mesa team. I know it's sad, but they must not reach civilisation, the world is not ready to know of other inhabitants in the universe. The mission is too great a task for our marines, so that is why YOU have been called!" Manners pointed at the marines. Dylan's face turned pale as he started to understand. "You have those both objectives, and the only objectable failure is death!" Now even Greshwald started wishing he had stayed home. They could always take on Arabs, but not something from another planet. "You also have a third objective," Manners continued and the projector switched to show a man in an orange suit. The man looked like one of the bookish type, except for his strange suit and the SPAS-12 in his hands. "This is Gordon Freeman, one of the Anomalous Materials group. He has been able to elude our marines for a long time now, and was last sighted in the rocket testing facility. This man was capable of clearing the room out of three gigantic tentacles, and is armed to the teeth. Try to take him alive, but obviously dead is fine too." Dylan did not seem so impressed by Freeman. He looked like one of the nerds at high-school.

Dylan suddenly seemed appalled and intrigued when the projector showed a small lump of pink skin with stubby legs. "Our soldiers have catalogued 3 aliens and their behaviour, though it is important to know sights of up to a dozen different aberrations has been sighted. Now, enemy #1: subject HC-9, dubbed headcrab. This little bugger moves slowly, but is able to spring from the ground at extreme speed. It is a small thing, but dangerous. The headcrab always aims for the head. Once there, it will slice open the scalp and dig into the brain, taking control of the host. Kill them with all means necessary."

Now the projector switched to show a red clump with a mouth and an incredibly long tongue. "Enemy #2: subject BN-29, dubbed barnacle. This is the least dangerous enemy when sighted, but should still be avoided. The thing is immobile and is latched onto the ceiling. It will constrict anyone under it with it's tongue and pull him up into it's mouth, where it will continue to bite the person in half. It's immobility is a virtue, for it is easy to walk around. Do not kill them if you're ammo is running low."

Greshwald screamed and Dylan felt sick when the third alien was shown. It was a humanoid-like beast, covered with wrinkly brown skin with patches of green here and there. The thing's face was covered with red orb-like eyes, covering the face like a bad case of herpes. "This is enemy #3: subject AS-33, dubbed the alien slave, due it's blind obedience to the greater aliens. Don't think it's status makes it any easier to kill, the alien slave moves at alarming speed and is capable of amassing a high charge of electricity into it's body, which it projects as a beam at the enemy. Kill them on sight, do not let them live."

"That is all. Be sure to check your weaponry and eat your rations, this will be a long day," the lieutenant concluded. The marines groaned and Dylan felt like his mother had been taken hostage by terrorists.

"Man, we are in SUCH deep shit!" Greshwald cried out, and most agreed with him. Most started to wish they had become civilians, and they continued till Dylan was about to scream.

"Dammit you fools, what the Hell is wrong with you?!" he stood up. "We were trained to fight on, no matter what the enemy was. I know this is a bit more literal than what they meant, but Hell, they're living things just like us! We're meant to kill without objection, and the enemy's amount of eyeballs doesn't change the fact. I'm gonna go kick alien ass, and I'll be damned if you don't do the same!"

Dylan's speech brought more courage to the men who cheered, and by the time the first Black Mesa buildings appeared, the guns were checked and the men's stomachs full.

I know, it's long, but I want to right a real thing, not some short piece of text. Expect more action in Chapter 1, and ciao!
