Found this pretty disappointing, unfortunately. I think fps games that feel this way are just not my preference. I actually liked being able to stealth around the levels more than engaging with the enemies. I don't have much experience with fps like this, but many of the levels didn't feel very well designed or fun to shoot through. One of my biggest problems was how tanky enemies eventually got. The normal soldiers are always around, but when the armored guys and robots show up they're such a massive pain to deal with. The story is fine but it's paced really weird, and it ended up feeling kind of anticlimactic.
