Oh come on, is this even Build?
Played the first level. The game is certainly good. The levels are large, intricate, complex, interconnected, all the areas have a sense of purpose unlike so many 'old school shooters' with their abstract level design. Some guy on steam was complaining it was too complex which makes me lol. I think the level of complexity used here is spot on. Obviously the levels look fantastic; full of colour, detail, and what I think is a simpsons reference in the skybox. At least the level I played had a bit of a SiN feel in the way you were going through a high tech facility. The levels certainly have the level of polish, consistency and custom for-purpose textures that you'd expect of a commercial product.
Combat is also of high quality; as others have said, the enemies aren't bullet sponges. You're also forced to use all weapons and hunt for ammo, and all weapons are useful, even the pistol. The enemies have a bit of punch to them, so you can't just go in guns blazing, you need to be smart about using cover. Fortunately, there's plenty of cover around; convenient crates, desks, walls. Plenty of windows around (including transparent cover) which allows you to see enemies in advance and plan your tactics. This gives the game more depth as opposed to Duke 3D. Another guy on steam also commented about being disappointed that there were 'so few enemies at any one time'. But this isn't Doom or Serious Sam, nor is it meant to be.
Interactivity is also in many ways more than I was expecting. You can push some things like chairs around. I love shooting the paintings. Shooting windows leaves cracks on the glass. Many, many little details. The moving sectors have momentum to them (slow start/stop) as opposed to Duke's constant speed. Omg that elevator with the guys in it...
On other hand, in some areas I was let down by the interactivity. It's great that you can use the toilets, but you can't
use the toilets

Further more, you can't use things like vending machines. There was also this bathroom with a hand towel dispenser, taps, and (what I think is) a condom dispenser; none of which you can interact with. I understand that the game can't have infinite interactivity, and they've come a long way in what they've done, but these particular components stood out to me as should be interactive but aren't.
I was also surprised by the performance issues (on my albeit 7 year old computer), but then I haven't tried the performance tips yet.
