As if it wasn't enough of a complication that he was dealing with creatures known for being difficult to kill, they had machine guns as well. Wesker caught sight of them before they opened fire, and dodged quickly out of the way.

Wesker was too quick for human eyes to follow, but he wasn't sure if the vampires were capable of following his movement.

He returned fire from his new, slightly closer position, one shot at each vampire more in an attempt to get them to stop firing for a few seconds than out of any hope of killing them with one bullet each.
