Played it, and i really liked it, as well. And it does look quite pretty, too.
I´ve even started a second playthrough. But those difficulty levels kinda confuse me. Reading the Wiki didn`t really help, either. Anyone know what exactly changes in the Ranger difficulties? I mean, Ranger Easy sounds a bit...easy? And the other one is hardcore, and that sound a bit difficult. And then there`s just Hard difficulty. So, yeah. A bit confusing.
But the game itself was fun. Gave me a few jumps (I´m easy to scare, so i consider Metro to be of the action-horror genre).
