This is what I got so far. The other half will probably be breaching the facility.

Simon maintained his pace with Spectre, as the Hunter lead the way towards where the rest of the fireteam was located at. Both Guardians ran through the building snow and icy winds as the inevitable blizzard was upon them, undeterred by the natural elements while they raced to their objective. But even the wisest warrior of the Light knew better than to fight in a raging snow storm and that fact alone probably kept them going aside from chance of coming across any hostiles.

"Looks like everyone got scattered across the plateau; I can't pinpoint anybody and this weather is certainly not helping." Cipher complained while continuing to try and make contact with anyone nearby.

That was worrisome. If they couldn't detect any of their fireteam members before the blizzard hits, they would practically be on their own and stranded from any friendly support. Simon began to plan ahead if in fact they needed to take shelter to outlast the storm.

"Located any beacons by any chance, Spectre?" Simon called out to the Hunter, "If we can't rendezvous with Andromedai or anyone before this storm scrambles all communications, we'll have to find some other way in get in contact with them. May have to get a hold of the Tower if need be."

Just as Spectre gave his input, two loud sudden bangs from a discharging sniper rifle could be heard echoing close by, over by a large rock formation they had been sprinting around. Cipher was quick to localize the origin of the gunfire and marked the point of detection on his HUD. In quick response, Simon jerked his head to the right, facing the direction of the source of the shots.

"Spectre, Did you hear that? Three o'clock over that small cliff face!" alerted Simon as he drew his auto rifle from his magnetized back panel.

Using his armor's jump jets, he boosted over slanted cliff, using any natural steps as leverage as he continued his ascent. Upon reaching the top, Simon could clearly identify the crashed shuttle, now looking nothing more than smoldering clump of metal. Unfortunate as it was to lose such a finely built craft, the two Guardians had more pressing concerns to worry about. Overlooking the wreckage, Simon could then identify Andromedai holstering her rifle and Kala, both tugging the downed body of Aiden-12 into cover. Scanning the area, the Titan could not make out any other signs of hostile opposition.

"Guardian down. Let's get over there to provide backup." as he began to slide down the other side of the cliff face. He was unsure if Spectre had heard him but is motion sensor confirmed that the Hunter was moving with them. 

Apparently everyone else who had already been on their way or were lured by Andromedai's gunfire had arrived, all accounted for too except for their pilot whom was not among them as Spectre queried. However no reply back had been given, possible in part due to Andromedai's concern with the rapidly approaching storm as she ordered everyone still able to fight to converge on the nearby military complex. Upon learning of facility's location, it almost seemed more unfortunate that there they were shot down so close by.

Given the amount of time Simon and Spectre had be traversing the snowy landscape, trotting as a team over the the complex didn't take much long until they reached the perimeter. Andromedai observed the military facility possibly for a minute, looking for any signs of any hostile activity before ordering the fireteam move onto the complex itself once more. Instead of taking the main entrance, it was tactically more efficient as their leader pointed out to breach the rear entrance; Simone couldn't happily agree more as he stowed his auto rife away for his Invective auto-fire shotgun.

Once the door had been kicked down off from it's rusty hinges, everyone surged through the first floor, checking all rooms and corridors, undeterred with with the messiness of years of without human touch to the place. As was displayed from the outside, there were no hostiles to be identified here. However, there were still several more floors to clear out as Andromedai pointed out and going by the fact how loud they were getting in, anyone who was inside would have been alerted right away. Veruna, Zeruel's Ghost, spoke up for him in taking the lead in the next breach into the second floor. Likewise, Simon and his other teammates formed up on him.
