Thanks to Michael Read, Tim Partlett, Steven Bender and Rasmus Hoejengaard at Crytek for their support, ideas, contributions and hospitality in Frankfurt. Thanks also to Guy Perkins at EA, and Steven Hall, Richard Morgan and Peter Watts.
Particular thanks to a very patient and diplomatic editor, Marcus Gipps. And to Chris Edwards and Cat Halsworth, the former for help with research, the latter for putting up with the research (we were playing video games).
