Well, I downloaded the demo and jumped right into the game. The graphics were really impressive, but with a Geforce 2 MX400/64Mb I had to run at 640x480 to get the screen to animate faster than Photoshop filters on an old 386. And I'm assuming that the controls are discussed in detail in the readme, but for jumping right into the demo, it seemed as tho they just weren't common sense (and I did go through the options to figure out what was what before hand). And then the gameplay... not to crazy about this. Seemed very slow and for having a silenced pistol and having tripped a bunch of alarms, I didn't have much of a fight.
Maybe there's more to the game and it was probably discussed in detail in the readme, but I'm far to busy at the moment to want to figure it out.
