How "accurate" will Guard Duty be?

Hello,

so I'm a bit of a Half Life fan, and despite their age, I still adore the old Half Life 1 games. I freaking loved Black Mesa: Source, and when you guys release your two remakes of the add-on packs when you can finally say "it's done", I will definetly be first in line to download and play the death your vision of the HL1 expansions.

So, I wanted to ask a curious question, how close will Guard Duty be towards Blue Shift? See, while I do love HL1, I must admit, I do feel Blue Shift was the weakest out of the 4 HL1 games (Decay not being much better either), and I think it's safe to say that alot of Half Life fans aren't massive fans of Blue Shift either.

So, do you feel differently, and that Blue Shift is a really great game, and that the remake will try to be as close as possible to emulate it. Or do you feel that Blue Shift was an expansion that could really use improvement, and that your version may differ quite significantly?

Thanks for any answer, and good luck on the rest of the project.
