Stepping off the Pelican, Mal quickly ducked out of sight of the pelican. He was looking for the central command room. He entered a corridor. He turns left, right, right. He was sure he was deep inside the glacier, with a temperature drop to prove it. A doorway, closed came up ahead. He shot the lock and opened it. Inside was a few grunts that were focused on some monitors showing a feed of outsides battle. Four shots rang out, and four dead aliens hit the floor. Then he saw something he hadn't seen before; some kind of blue energy field. It shimmered in the doorway, casting light in the area around it. Inside was a marine. He walked over, he didn't know if she had seen him, or even if the field let sound through. He let loose a few rounds into the shield to gain her attention.
