Project Prometheus

Tom Costigan is a washed-out mercenary, stuck cleaning dishes for a hole-in-the-wall bar despite his chrome arm and the computer in his head. While having a smoke break in the alley out back, he's approached by a former comrade. His former commander is putting the old team back together for a big corporate heist.

Tom isn't big on asking questions, and the money's attractive enough to make him jump for it. But when the hand-off to the buyers goes south and the bullets start to fly, Tom finds himself with a sealed container and the payout.

But the payout is encrypted, and he doesn't know what's in the container.

Even with the help of his hacker sister, will Tom be able to stay ahead of his former comrades, the buyers, and the people they stole from and why is everyone willing to kill for what looks like a bunch of silver goop?
