There are dozens of survival games now, but DayZ still feels like lightning in a bottle. No game before or since has done such a good job of creating tension among players, where the occasional sighting of another human seemed filled with possibility and threat.
It's for this reason alone that I'm interested in Icarus, a scifi survival game from RocketWerkz and Dean Hall, DayZ's designer. An eight minute in-fiction 'documentary' did not give me a second reason.
