Fits the screen perfect imo....I didn't notice anything off about the hud but it's just for reload and weapon selection I think anyway as far as what it shows.
I LOVE it...i was kinda burnt out by #3 and kinda limped through that one many years back but this one I felt like I felt playing the first one. Story isn't as great as the original since but i enjoy the story. Graphics look gorgeous to me and I love the sound. The AI is a little less than in the past but it kinda fits into the story the fact the enemies aren't.
I'm sure some hard core fans could complain about some parts of it but I don't have any complaints really, just little things, etc. I'm about 2 hours in I think.
Was going to upload a video but someone already did:
