The game looks better than in previous gameplay videos and I dont mean simply the "graphiczx", but also the animations, that seem more fluid, especially the hand to hand combat. The player character also seems to have more weight to his movement, maybe this is just because he's moving slowly though.
The aiming works like an improved version of Deus Ex and Vampire: Bloodlines aiming. It's important to me to get that crosshair as small as it can, it really gives you the idea that the shot is gonna have greater accuracy. One of the problems with Bloodlines was that no matter how proficient you got with weapons, the crosshair never got that small, and your shots looked like they were going to miss, even if they weren't!
The perk selection screen is functional, but I hope you can change through them quickly without having to go to that screen all the time. I like it that the perks are obtained like gameplay achievements, and not something that you select at will during character creation and levellup.
Also, the music in the background sounds really good, both during the stealth sequences and the fast paced action.
