Part 3. Rejoice, you're getting a two-part special today.

I have part 4 almost done, so providing GTA4 doesn't distract me for the next few hours, I'll throw that up sometime tonight.
As always, comments are appreciated.

Part 3: Dead World
45 years, 3 months, 12 days and 16 hours after The Incident
3 minutes since Mission Start
Flynn hopped out of the dropship's hatch and onto the thick layer of snow that covered the ground as far as the eye could see. He sank up to the knee in the sea of snow, almost losing his balance. He moved out of the way to let the others disembark from the ship and paused to look around.
The marines had spread themselves out in a rough circle around the dropship, some crouching behind boulders that were half-burried in the snow. The landscape of Glacies Prima was a desolate wasteland. Nothing but snow, ice and mountains extending as far as the horizon. Flynn looked around to see if he could spot the outpost, but everything just looked the same to him: white.
"Nice place." Carter remarked as he stumbled through the snow towards Flynn, followed by Quinn who seemed far more at home in these conditions than any of the others.
"Yeah, the perfect ski-resort." Flynn replied.
He looked around at the small team and located who he was looking for, Connor, talking to Sergeant Hanson, who was looking at a display screen on a briefcase sized machine that he immediately identified as a portable scanner unit.
"....sure that there's nothing?" Connor was saying, concern evident in his voice.
"Nothing." Hanson confirmed, holding the scanner up higher so it could get a better reading. "Not a damn thing. Well, nothing we're reading as human, anyway. Plenty of those bugs, but no people."
"Right." Connor said with a sigh. Until now he had hoped whatever had happened here was just an equipment malfuction. But with the residents of the base missing..... "Look, we'd better get moving. I want to get to Outpost Alpha as soon as possible." Hanson nodded in agreement, then called the team together.
"Okay people, we've found nothing on sensors, so we're going to have to check out the base ASAP. The facility is just a mile in that direction." Hanson pointed towards a distant white hill that Flynn had simply presumed to be a rock formation. Now that he looked closer, he fancied that he could pick out a glint of metal here and there. "We still don't know what's going on, so I want all of you to stay sharp and keep your weapons ready. Understood?" There was chorus of "understood"s from the civilans and marines. Flynn noticed that Carter had raised his hand to get Hanson's attention. Hanson noticed it too. "What?" He asked bluntly.
"Well, you just said that there's no one around. Why the need for all the guns and stuff? It's just an empty complex. What's there to worry about?"
"No." The Sergeant corrected. "We
think there's no one in there. There're ways of hiding from scanners, or jamming them entirely. So until we know for a fact that there's nothing there then I'm going to treat that place as if the goddamn legions of Hell are hold up inside. Understand?"
"Yeah, sure." Carter said, shrugging. He obviously didn't, but wasn't interested in arguing the matter any further.
"Good. Any other questions?" The group remained silent. "Good. Let's head out. Harrison, Strauss, on point. Sven and Sinderman watch the rear.
You lot," He said, pointing at the knot of civilians. "stay in the centre of the group until I say otherwise.
Eagle 1," He called into his helmet's comm unit, adressing the two marines crewing the shuttle. "we'll take it from here. Head back to the
Europa."
If Hanson got any response then Flynn didn't hear it. Instead, the dropship's engines flared up, instantly vapourising the surounding snow and ice, and the craft shot off towards the orbiting starship, leaving the small group of investigators alone on the dead world of Glacies Prima.

Hanson dropped to the ground quickly behind some sort of half burried tractor vehicle and trained his binoculars on the outpost. The external defensive walls were almost invisible beneath the coating of snow it had gathered in the four and a half decades since there had last been any known life in the base. If someone was still occupying it, then they obviously weren't too interested in keeping the exits clear. Only one of the complex's buildings was visible over the top of the three metre tall steel wall. There were no lights on, and Hanson could see that the windows were broken. The perimiter towers that were erected at every entrance and corner of the base were in a similar condition. No sign of life, but signs of damage.
Things didn't look good. There was no sign of any of the base staff they had come to check up on. On the plus side, there was no indication that the base was anything but dead. Still, Hanson had quickly learned that complacency just got you killed quicker. Best to be careful.
"What do you think?" He asked Private Strauss, who had acompanied him ahead of the group to reconotoir the base's exterior.
"I think it's empty, Sir." He answered, also inspecting the base through his binoculars. "I think the only thing we need to worry about is how to get into the complex in the first place." He commented, gesturing at the large piles of snow that had built up around the entrances. Hanson frowned. The soldier had a point. Getting through all that wouldn't be easy.
Still, the first thing to do would be to get the team regrouped together. The place seemed safe, so it'd be fine to bring the civies up here as well. Maybe one of them would make themselves useful and find out a way to get through that didn't involve digging.
"Hanson to Sven." He called his second in command quietly over the comms. There was a moment of silence before he got a response.
"Sven here. Go ahead."
"Corporal, where the hell are you and the others? You should have been here twenty minutes ago."
"Sorry Sir. That Carter guy took a trip down a crevasse. Ve spent a vile trying to get him out. Ve're just about 200 metres from you're position. To the south."
"Right, well hurry it up. We're going to need to dig through to the base, I think. The facility looks empty from here, but keep an eye out."

In the end, it had taken them about half an hour to dig away enough snow to get through to the small southern entrance. With that done, it was just a matter of entering the code and going inside. That task quickly proved to be easier in theory than practice.
"Got a problem, Sarge." Called Harrison, the squad's technical expert, from the electronic door panel he'd been inspecting.
"What is it now?" Asked Hanson, aproaching.
"Well, see this thing here's an electronic lock."
"Yeah, and?"
"And it works by electricity."
"Yes, so what?"
"There is no electricity." Harrison said, gesturing up at the perimiter tower that stood next to the entrance. The floodlight on the tower remained inactive.
"Shit." Hanson swore. "Well, now what?"
"Well, I could probably hook up one of our portable power packs to the panel. That might get us through, depending on how well made these things are. Or we could just blow the door off completely. Whatever works."
Hanson thought about it for a moment. Simply blowing the steel shutter to shreds and gaining access to the facility as quickly as possible was tempting. However, if there was anyone inside then the blast would be sure to alert them. He decided to go for the quiet option. They still didn't know what was going on, so it wouldn't be a great idea to advertise themselves.
"Hook one of the packs up." He ordered. "Just get it done quickly."
Harrison got to work, and within ten minutes got the panel functioning again. Then they hit the next problem.
"Got it!" Harrison yelled triumphantly. "We just need the code now."
"Right, let me through." Connor said, getting up off the rock he had been sitting on. He had spent the last ten minutes while they waited for the door to be powered up trying to memorise all the facility's codes, which he had written down on a piece of paper and shoved into a pouch on his space suit. Holding the piece of paper in front of his helmet so he could read it, he tapped the code into the flickering panel. Nothing happened for a moment, and then the panel gave a load bleep and displayed a message.
CODE OUTDATED
"The hell?" Connor said, frowning. He typed the code in again, but got the same result.
"How old is that code?" Hanson asked him.
"It's the newest code we have for this base. Every time the facility sent a message, well, every time they sent a proper message, they also transmitted their latest access codes. They never changed them once since the base was set up."
"Apparently they did." Hanson said, looking at the panel.
"But why'd they do that?" Quinn, who had wandered over, asked. Connor just shrugged.
"No idea." He said. "Maybe they felt they were under threat?"
"From who?" Hanson asked. "The Earth government is the only group that would have had the codes, and none of them gave a damn about this place until the Director here decided to go crazy and start screaming down the comms at Earth."
"Well...." Carter, who had just joined the steadily growing group of people at the door. "What if it wasn't Earth they were worried about?" Connor snorted derisively.
"Then who were they worried about? The only ones who knew about the codes were Earth and the scientists here themselves. Changing the codes wouldn't offer them an ounce of protection from anyone else."
"Well then, what if it was one of their own guys they were worried about?" Carter asked.
"So they decided to throw one of their own coworkers out outside the base walls to let him freeze to death? Sorry, but I don't see that happening. Now, let's get back to the real issue at hand: how we're going to get inside."
"I could try and bypass the system and get the door up." Harrison suggested.
"Right. Do it." Hanson told him.
