Played it a bit, but haven't even gotten through the first mission yet

Mostly because I'm being really careful, to avoid being spotted at all costs. Got the Ghost Achievement (and Exp bonus) for the first part of the mission^^
A nitpick I have:
They've got a model for the player character, which you can see at any point, simply by going into cover.
So why isn't there a player model in the first person view?
If you look down, you see the ground only, not even a shadow and if you sprint and look down, your hands still move forward in the direction you're looking, which is kind of silly...
It can't be about performance, since you can go into cover pretty much everywhere, so they were probably just too lazy to make a separate set of animations for the PC, that are adjusted for first-person view.
It's nothing absolutely crucial, but it breaks the immersion imho...
