1 - Close on Chris' shocked eyes.
2 - Close on the dead Shifter, blood pooling around its head.
3 - Close on the Shifter at Chris' legs, pulling them out from under her.
4 - On Chris and the Shifters around her. Chris lies on the ground, eyes closed and making herself as small as she can. The Shifters are being hit by more bullets, some in vital areas, some in less key ones. A few go down, others make to leave. The Shifter on top of Chris is hit, thus why it doesn't tear the hell out of her. One way to render / emphasize the bullets would potentially be to have little insert boxes around them to make them pop more for the reader.
LETTERING NOTE: The BLAM!s should be all over the page to get across the point that there are lots of bullets / shooters.
SFX: BLAM! BLAM! BLAM!
5 - Close on Chris' still closed eyes.
6 - On Chris as she opens her eyes to see a set of legs standing next to her pointing a gun in her direction. The top of the figure is cut off by the panel edge. Chris is terrified.
7 - Similiar panel, but it becomes clear the figure is aiming at the fallen Shifter next to Chris. The figure pulls the gun trigger, killing the Shifter.
Start from the beginning.
