Do you know of its any better than metro 2033? I found the movement of monsters/npcs, artyom(your character), and the gun sight all very choppy. At least in the demo.
It is part of a Steam Flash sale at this moment-$30 (about 3:15 left as of this posting).
I did not get it; my brother has it but hasn't played it yet. The Metacritic score is 82 (if you put any credence in that metric). I would buy it (and I am not much for shooters these days ).
