Hack the gun and flee

Sombra did some calculations in her head. It takes most trained gun users about .25 seconds to shoot a gun once it's aimed. Hacking a weapon takes about half a second, which means she usually has to hack a gun before its owner sees her. But most gun users aren't nerdy scientists with glasses...

Eh, she's taken bigger gambles.

She hacked. Mei fired. The freeze gun glitched just as it was forming an icicle, causing a cryo-explosion that froze Mei's arm up to the shoulder. She cursed again in Chinese, smashing her arm on a nearby desk to break it free. By the time she got her blaster up again, the hacker was gone, along with her submachine gun. She looked up at Snowball, who gestured to one of the doors leading out of the lab, and got ready to go on the offensive.

Meanwhile, Sombra found herself back in the vents again, catching her breath. The camera drone softly bumped into her a few times. Sombra took the hint and unmuted Mr. Black.

"That was...amazing! Completely unflappable under pressure. Well...well done!" Sombra couldn't help but smile. This was the most excited she had ever seen the shadowy figure. "So, what's the plan now?"
