That looks quite fun. Like a stealth version of dark souls invasions.
Although simply clicking on people and being told 'not hacker' in 0.1 seconds is a bit disappointing....trying to analyse who looks suspicious from behaviour (walking patterns/people trying to hide/making use of blind spots) would be more interesting.
(*Is that would assassins creed multiplayer does? Not sure, haven't played it)
But in this one a hacker has no reason to daringly walk straight past his hackee like a regular npc, because the target will just be spamming one button on everything.
