Saw this on TIGSource and was immediately intrigued. It's an indie game entitled Illegal Communication, a 'cyber adventure' with wireframe green on black visuals and... well, that's all I should say. The programmer deliberately gives no information about the plot, the objectives or even the controls - players have to figure everything out for themselves. In the whole ludology vs narrative debate, this is surely the ultimate realisation of the former standpoint?
There have been a few titles like this in the past - most notably Activision's 1985 classic, Hacker, but I can't imagine a commercial release ever trying it again.
