Barrett tears elevator doors off

"Go tactical" ordered Namir.

The elevator doors came off their mountings in a screech of torn steel, and
Barrett swung out behind them, snorting with effort. He dealt with
the guard closest to him with a savage backhand punch that drove bone
shards up into the man's forebrain. The guard dropped to the
unfinished concrete floor, twitching as he died. Namir and Hermann came in
a heartbeat later, their machine pistols snarling. Armor-piercing
rounds sprayed in fans, taking more kills.
