As the blizzard came upon the squad, HC-42 noticed that Gwal, Leep, and Sasha began to panic. Hordes of undead reptilians began charging toward the area. HC-42 had no idea these kinds of forces were at play, but was determined to complete his objective nonetheless. Sasha didn't sound as enthusiastic, however.
"First those damn droids, and now this! We can't possibly hold out!" She said as she fired on the lizards, her sharpshooting abilities allowing her to incapacitate several.
"Squad, this is a mere setback. These reptilians may be undead, but they're primitive. I calculate they will melt away soon as long as we keep the pressure on them."
"I don't think 'melt' is the right word in this weather. Also, what about the droids? They're shutting the entrance, we need to act soon if we're to compete our objective." Leep said.
HC-42 pondered this, but soon calculated a way to get the squad to their objective. It wasn't textbook at all, and was risky, but had a chance of eliminating a lot of resistance if successful. The droid took all of his available thermal detonators, and tied them together.
"Sasha, you and I will concentrate fire on all droids and reptilians guarding the entrance to cover Gwal and Leep! Gwal, I need you to charge to the closest droids and reptilians and engage in hand to hand combat! The intent is to distract them. Leep, charge toward the door firing all the blasters, use your cybernetic legs to gain speed and to jump over obstacles, then when close enough, arm the thermal detonators and toss them through the entrance! Then run back here, taking out as many enemies as you can on the way! If we succeed, the thermal detonators should neutralize all the enemies inside!"
The squad didn't have time to argue the strategy, so they instead took a moment to do a group hug that made HC-42 uncomfortable. He played along, however- it may be the last time he sees his squadmates, should his strategy fail.
When the tenderness was over, the squad started doing their respective duties. HC-42 began firing his heavy repeating blaster at all enemies guarding the entrance, with Sasha sharpshooting any that were missed. Gwal then charged to the nearest enemy and pummeled it to the ground with his thick cybernetic arms, before shooting it while it was down. He then engaged another, picking it up and tossing it in the path of enemy fire, killing it. He then grabbed two, using them as shields against enemy fire. Leep was already making good progress. He used his signature "blaster kata," as he called it, to mow down any enemies that were quick enough to notice him charging amongst the chaos. When he was close enough to the entrance, which was almost closed, he armed the detonators, and rolled them underneath the door. He bolted back the other direction, ambushing confused enemies with blaster kata along the way.
Gwal was starting to get overwhelmed when Leep came back and took out a few enemies for him. The rest got mowed down by the heavy repeating blaster that HC-42 was firing.
And then the detonators... well, detonated.
