Nice to see a highly tweakable game for PC again, both in the control settings and visual department.
Mouse/keyboard input is freely configurable, where you will like to turn off interfering shit like mouse smoothing/acceleration.
Don't know how demanding this game is, but I run everything maxed out without probs.
Bit dated graphics, but adequate =>

After a thorough tutorial introduction to the controls gameplay is good.
A satisfying mix of stealth (when patient) and action (when restless).
The killshots are delicious slomo horrors of your accurate snipage.
Of course it gets a bit repetitive, but that's pretty much inherent to the shooter genre.
I'm having a good time with this, it's very well put together.
Definitely worth more than how most reviewers score it.
