You don't need a history to have a future

A soldier gets a second change in life. He is killed, but thanks to science he comes back resurrected, improved and enchanced. He's now a robot really, a super-computer and indestructible soldier in flesh, blood and some badass nanotechnology. To avenge the death of his wife is the first agenda, but ends up a pawn between scientists power struggle. A techno thriller in every sense of the word, humbug shit really, but pretty well done.
