she's back

A character in a gas mask and white coat stands on a wooden deck, then runs forward as two allies in similar gear join, moving across the deck toward a distant figure; the scene shifts to a close-up of the character's legs, then to a wider view where the character aims a weapon at a group of enemies, one of whom is thrown into the air as the others are hit with red impact effects. The setting is a dark, industrial ship deck under a stormy sky.
