Sci-Fi Squad Ambushed by Beasts in Frozen Wasteland

the prompt

Cinematic long shot with forward tracking: In a frozen wasteland under a black sky filled with auroras, a small squad treks across an ice ridge, their footsteps crunching over ancient wreckage. Wind howls. One pauses, raising a scope. In the valley below: dozens of beasts, dormant, coiled around a shattered mech carrier. The camera slowly tracks forward as the squad descends each step heavy, uncertain. Then one of the creatures stirs. Its eyes glow. Others follow. The ice begins to crack beneath their feet. The camera pulls upward as all hell breaks loose, beasts charging up the slope, soldiers scrambling, rifles lighting up the darkness in staccato bursts.
