Now did he really have to kill that guy at the end? He was just minding his own business and it didn't seem like he was in the way of where he was going either as he just turned around and left and he snapped his neck, he was just showing off! "Oooh look at me I can kill people through walls~!" :p
This one will likely be good, Deus Ex 2 was a dissapointment so a decent sequel is long overdue!
