HL2E3 Fan Script, Chapter 1

Peering down at an airfield through binoculars, Gordon watches as a helicopter lands, almost silent at such a distance.
Several Combine soldiers trudge out, a more lively crew replacing them almost immediately; and as soon as refuelling is complete, the helicopter once again flies off into the distance.
Gordon looked to his side to see a shivering Dr. Kliener, barely recognisable under an abundance of snow gear, scrawling down "18:00" on a sheet of paper, many more numbers preceding it. "This Alaskan climate is just the worst" he remarked; "Thank goodness our shift is over, now let's get ourselves warm".
The two trudged towards to a snow-covered door in the hillside, which opened as two fresh replacements walked out, much like the scene just viewed through the binoculars; which, of course, Gordon was just liberated of as he and his replacement crossed paths.

Walking inside the crowded bunker that a sizeable rebel force had set themselves up in, Kliener stuck his time log on a wall, underneath a "12:00-18:00" label; and for every six hours for the last two weeks prior, there was a similar log, not a single event on the airfield having gone unnoted. A large "DROPSHIPS ON STANDBY" note dominated one page on the wall, accompanied by a sketch showing which hangar they went into.
"It's been days since even half an hour has passed without a helicopter being sent off to the Arctic." said Kliener, looking over the mostly-covered wall dedicated to time logs. Turning to Gordon, he added "By my estimates, they've searched about a third of the Arctic. They're bound to find the Borealis eventually, so I hope you're ready to leave at a moment's notice!".

Gordon idly wandered the bunker, unsure of how to spend his time off-watch.
This bunker didn't just hold the elite combatants chosen to destroy the Borealis, as everyone knew must be done lest the Combine reverse-engineer it to bring their armies in vast numbers; the bunker also housed tradesmen, scientists, and engineers who busied themselves keeping those combatants well-equipped.
Gordon recognised many scientists and engineers from Black Mesa, and some were handling the limited resources at their disposal better than others; a humorous example being one dismantling a concrete wall to retrieve the iron rods inside, while another desperately searched the exposed rock for pitchblende.

Not ten minutes had passed though before someone alerted Gordon to an event occurring outside, and he rushed out to observe the commotion.
The two people on watch were hastily talking to each other, then handed Gordon the binoculars and ran inside.
Taking a look for himself, he saw that a helicopter had landed, and simply been abandoned as many Combine soldiers mobilised, running all over the airfield.
It was the sure sign of the Borealis being found that the rebellion was waiting for, and on-cue a car burst through the wall of snow that was hiding the garage, Alyx in the driver's seat.
Many cars were in the garage behind her, and all the cars were painted white and being filled with rebel soldiers armed to the teeth.
Save for Alyx's car; it was painted white, but had no room for soldiers as one seat was reserved for Gordon and the two back seats were taken up by a "dog" with a large bomb on his back.

Gordon jumped in the car, and immediately the convoy made its way downhill, the white vehicles barely visible against the snow.
The hangar containing the Combine dropships was opening as the convoy parked amongst some trees, close to several dropship containers.
The vehicles were abandoned as the soldiers headed for the containers, opening their doors and slipping inside.
The most cluttered of the containers was left for Gordon, Alyx, and Dog; the latter of which was first to climb inside and clear a space for the group behind a pile of heavy machinery.
With everyone hiding in containers, the rebel force waited in complete silence for what seemed like far too long.
Alyx breathed a sigh of relief as a dropship clamped onto the container, and began lifting it into the air.

The Combine had at last found the Borealis; but little did they know, they were bringing a small rebel army right to it.
